Pool Decking SA 2026 - Complete Pricing Guide

Pool Decking Costs in South Australia for 2026

Pool decking around an Adelaide swimming pool creates one of the most enjoyable outdoor spaces an SA property can offer, but it also involves construction challenges and compliance requirements that do not apply to standard garden decking. The combination of constant water exposure from pool splashing, chemical exposure from pool sanitisation systems, high UV in SA's summer, and the foot traffic pattern that concentrates around pool edges creates a demanding environment for decking materials. Add the legal requirement for compliant pool barrier fencing in SA and the need for a surface that is safe when wet, and pool decking becomes a project where material selection, structural design, and compliance knowledge all matter significantly.

SA homeowners building or renovating a pool deck in 2026 have more material options than at any previous time. Traditional hardwood and treated pine timber remain popular for their natural warmth and visual integration with garden settings. Composite decking has matured considerably and is now available in profiles and textures that genuinely approximate the appearance of timber while delivering significantly lower maintenance requirements in the pool surround environment. Aluminium deck systems are a niche but genuine option for homeowners who want a zero-maintenance, non-organic pool surround that eliminates all rot, decay, and coating concerns entirely. Understanding the performance differences between these options under SA's specific pool environment conditions is the foundation for making the right material selection for a project. For full treatment class guidance and the fixing requirements for treated pine near pool environments, our treated pine decking SA guide covers specification for pool surrounds. For the full range of hardwood species suitable for SA pool surrounds, our hardwood decking SA guide covers natural durability, Janka hardness, and maintenance requirements for each species.

Material Selection for SA Pool Surrounds

The material selection for an SA pool surround involves balancing appearance, durability, slip resistance, maintenance commitment, and cost over the intended life of the structure. No single material is perfect for all SA situations, and the best choice depends on the specific pool environment, the aesthetic priorities of the homeowner, and the realistic maintenance commitment that will be maintained through the life of the structure.

Treated pine is the most affordable pool decking option and delivers a warm, natural appearance that integrates well with garden settings. For pool surround applications, H4-treated pine is the minimum appropriate treatment class because pool surrounds are classified as in-ground or close-to-ground applications with persistent moisture exposure. H4 treatment provides resistance against the fungal decay and insect attack that H3 timber cannot adequately resist in the constant moisture environment of a pool surround. Treated pine pool decking requires annual oiling to maintain its surface protection and to minimise checking and splitting from SA's UV and heat cycling, and the oiling frequency around pools may need to be closer to six-monthly on heavily used pool decks where foot traffic and splashing deplete the coating faster than on an open garden deck. Treated pine pool decks typically last fifteen to twenty years with appropriate maintenance before replacement is needed.

Merbau hardwood is the most popular premium timber choice for SA pool surrounds. Its natural oils make it more resistant to moisture absorption than softwood species, and its density and durability mean it performs well in the demanding pool environment when properly maintained. Merbau's deep reddish-brown colour complements pool settings and ages gracefully to a warm grey if left without oiling, though regular oiling maintains the colour and significantly extends the structural life of the boards. A specific consideration for merbau pool surrounds is tannin bleed: when merbau gets wet, it releases a dark red-brown tannin that can stain pool coping, light-coloured pool surrounds, and occasionally discolour pool water if freshly installed merbau is extensively wet without having been initially sealed. A good quality penetrating oil applied promptly after installation, before the deck is exposed to pool water, significantly reduces tannin bleed. For more on merbau decking characteristics and maintenance, our merbau decking SA guide covers the full picture.

Composite decking has become the dominant material for SA pool surrounds in new installations over the past five to eight years, and for good reason. High-quality composite products from Trex, Millboard, and Ekodeck provide a consistent, stable surface that does not absorb pool water, does not require oiling, does not check or split, and does not react to chlorine exposure the way timber coatings sometimes do. The slip resistance of composite decking is generally better than that of smooth-faced hardwood decking, and most quality composite products are specifically certified for pool surround applications with appropriate slip resistance ratings. The initial cost of composite decking is higher than equivalent timber at $420 to $680 per square metre installed, but the elimination of the annual oiling maintenance cost and the longer product life typically make the total lifecycle cost of quality composite decking competitive with or better than timber over a fifteen to twenty year comparison period. Our composite decking SA guide covers the product options and their specific maintenance requirements in detail.

Composite vs Timber Performance Around SA Pools

The performance comparison between composite and timber pool decking in SA comes down primarily to three factors: maintenance commitment, surface temperature in summer, and the visual authenticity of the timber appearance. Understanding how each material performs on these three dimensions helps SA homeowners make the decision that suits their priorities.

On maintenance, composite decking is the clear winner for pool surround applications. Timber pool decking requires annual oiling, which in the pool environment means working around pool access, managing tannin bleed during oiling, and ensuring the coating is fully cured before the pool is used again. Missing a maintenance cycle on a pool deck timber surface means the coating depletes faster than on an open deck because of the additional water exposure, and recovering from a missed annual oil requires more aggressive preparation before the next coat can go on. Composite decking requires only periodic cleaning with a composite deck cleaner and a hose-down, which is genuinely low effort. For SA families with busy lifestyles, the maintenance simplicity of composite decking around a pool is a significant practical advantage.

On surface temperature in SA summer, composite and timber have different characteristics. Dark-coloured composite decking can reach surface temperatures that are uncomfortably hot for bare feet on SA summer afternoons, and this is a genuine usability consideration for pool surrounds where barefoot use is the norm. Light-coloured composite decking runs cooler than dark composite, and both timber and composite run cooler than concrete or ceramic pool surrounds in equivalent conditions. Most composite decking manufacturers have developed lighter-coloured or heat-dissipating product lines specifically in response to the surface temperature issue, and these products perform noticeably better on SA pool decks during summer afternoons. Specifying a light to mid-tone colour rather than a dark charcoal or black composite for an SA pool surround is genuinely important for summer usability.

On visual authenticity, timber remains the reference standard. Premium composite products have improved dramatically in their replication of timber grain and texture, and products like Millboard Lasta-Grip and Trex's enhanced grain products are convincing from normal viewing distance. However, a close inspection reveals the difference, and SA homeowners with strong aesthetic preferences for genuine timber will typically choose hardwood for their pool surround despite the higher maintenance commitment. For homeowners who prioritise the combination of low maintenance and acceptable timber-like appearance, quality composite products provide a compelling package.

Slip Resistance Requirements

Slip resistance is the most critical safety requirement for pool surround decking and the one most likely to be under-specified on budget pool decking projects. A wet pool surround surface that does not have adequate slip resistance is a genuine injury hazard, and the consequences of a slip and fall adjacent to a pool can be severe. The relevant Australian standard for slip resistance in pool surround areas is AS 4586, which classifies slip resistance under wet conditions using a P scale, and Australian building standards specify a minimum classification of P4 for pool surround and outdoor wet areas.

For timber pool decking, slip resistance is achieved through the board profile choice and the surface texture. Decking boards with a ribbed, grooved, or wire-brushed face profile provide better wet slip resistance than smooth-face boards, and specifying a board profile with adequate surface texture for pool surrounds is the correct approach. Running timber decking boards parallel to the pool edge rather than perpendicular can also improve drainage and slip resistance by directing water away from the walking surface. Anti-slip inserts or strips can be added to smooth-face timber boards but are less effective than an intrinsically textured board profile. For an overview of all SA timber deck species and their suitability for pool environments, our timber decking SA guide covers the full material comparison.

For composite decking around pools, manufacturers typically rate their pool-suitable products for slip resistance and publish the AS 4586 classification for their specific products. The Millboard Lasta-Grip range, Ekodeck, and Trex's commercial-grade products are specifically developed for pool surround applications and carry appropriate slip resistance certifications. When selecting composite decking for an SA pool surround, confirming the specific product's AS 4586 classification is important, because not all composite decking products are rated for wet pool surround conditions. A builder quoting composite decking for a pool surround should be able to confirm the slip resistance classification of the specific product they are proposing.

SA Pool Barrier Requirements

In South Australia, all residential swimming pools must be surrounded by a compliant pool barrier under the Building Code requirements for swimming pool safety. Pool barriers are designed to restrict access by children under five years of age and must comply with specific height, climbability, and gate requirements. Understanding how the pool barrier requirement interacts with the pool deck design is essential for any SA pool decking project.

The key pool barrier requirements applicable to SA pools include a minimum barrier height of 1,200mm, gates that are self-closing and self-latching, no climbable elements within 900mm of the inside face of the barrier, and no gaps in the barrier that would allow access by a small child. The pool barrier must surround the entire pool and must not incorporate the walls of the house as part of the barrier unless the house walls meet specific requirements for doors and windows opening into the pool zone. For pool decks where the deck extends beyond the pool barrier, the area between the barrier and the pool edge is the pool zone, and no climbable elements including deck furniture, raised garden beds, or stepped features should be present within this zone.

The pool barrier fence and gate system is typically a separate cost item from the pool decking itself, and the integration of the barrier into the deck design is one of the most important design decisions in any SA pool decking project. Common approaches include glass panel pool fencing (the most popular premium option in SA due to its visual openness), powder-coated aluminium pool fencing, and in some rural and Hills settings, timber post and rail fencing designed to meet the pool barrier requirements. Glass pool fencing uses frameless or semi-frameless toughened safety glass panels that are point-fixed to the deck structure or to posts set in the ground around the pool perimeter. Frameless glass fencing costs $350 to $600 per lineal metre installed in SA and is the most visually unobtrusive option for preserving the view of the pool from the house and outdoor living areas. For guidance on pool safety regulations applicable to SA residential pools, the SA Government planning and safety pages provide current information on pool barrier compliance requirements.

Sub-Structure and Drainage Design

The sub-structure design for pool decking in SA requires careful attention to drainage because pool water splashing, rainfall, and the routine water movement around a swimming pool create consistent moisture loading on the deck sub-structure. Poor drainage design in a pool deck sub-structure leads to standing water beneath the deck boards, which creates ideal conditions for fungal decay in timber sub-structures and makes the deck surface slower to dry, increasing the period during which the surface may be slippery after pool use.

The key drainage design principles for SA pool surrounds include an adequate fall across the deck surface to direct water toward drainage points away from the pool, gaps between deck boards that allow water to drain quickly rather than pool on the surface, clearance beneath the deck boards to allow air circulation that facilitates drying, and drainage paths beneath the deck that prevent water from pooling against footings or in low spots of the sub-structure. On above-ground and semi-inground pool installations, the relationship between the pool wall height, the pool coping level, and the deck surface level needs to be designed so that water draining from the deck does not flow back toward the pool shell or collect against the pool wall.

The footing design for pool surround decking is a specific consideration because pool construction alters the soil conditions around the pool, and some pool construction methods, particularly for fibreglass pools, use crushed rock or sand backfill around the pool shell rather than compacted soil. Deck footings placed in this backfill zone need to be designed for the different load-bearing characteristics of backfill compared to undisturbed soil. In SA's clay-heavy soils, the soil movement that drives AS 2870-compliant footing design for house slabs also affects deck footing design, particularly for pool decks at the expanding and contracting soil interface. Experienced SA pool deck builders understand this soil behaviour and design footings accordingly.

Pool Coping and Deck Integration

The junction between the pool coping and the deck surface is one of the most important aesthetic and functional design details in any pool decking project. The coping is the finished edge around the top of the pool shell, and its relationship to the adjacent deck surface determines how the pool and deck read visually as an integrated space.

A deck that sits flush with or slightly above the pool coping level creates a seamless transition between the pool water surface and the deck, producing the most visually striking and contemporary pool deck aesthetic. Achieving this requires precision in the deck height design and construction, because the deck surface must be exactly positioned relative to the pool coping and this positioning must be maintained around the full perimeter of the pool. For fibreglass pools, which are the most common pool type installed across Adelaide's metropolitan suburbs, the coping is a factory-moulded lip that forms part of the pool shell. Its height above the installed pool waterline is fixed at installation, and the deck builder must design the sub-structure to bring the finished deck surface to the correct height relative to that fixed coping level.

The detail at the gap between the outer edge of the pool coping lip and the first deck board is a functional decision that affects both drainage and safety. Too tight a gap and pool water cannot drain freely between the coping and the deck surface, creating a wet zone that is persistently slippery and that accelerates deterioration of the first board. Too large a gap and it becomes a foot trap, particularly hazardous for children running around the pool edge. A gap of 6 to 10mm between the pool coping edge and the first deck board is the practical working range that balances drainage and safety for most fibreglass pool installations. The board immediately adjacent to the pool coping experiences the highest water exposure of any board on the deck and should be specified with stainless steel fixings and checked annually as part of the routine pool deck inspection.

For concrete pools, the coping is typically a separate tiled or stone element applied to the top of the pool shell wall, and the coping thickness and overhang profile are design choices that directly affect how the deck meets the pool edge. The weight of a cantilevered concrete coping that overhangs the pool shell significantly can create a stress point at the shell rim, and pool deck builders working with concrete pools should confirm with the pool builder or a structural engineer whether any proposed cantilever over the pool edge is within acceptable limits for the pool shell construction method. Our deck building SA guide covers general sub-structure design considerations that also apply to pool deck cantilever situations.

Above-Ground and Semi-Inground Pool Decking

Above-ground and semi-inground pools represent a significant proportion of the residential pool stock across Adelaide's northern, western, and growth corridor suburbs, and their decking requirements are fundamentally different from in-ground pool surrounds. An above-ground pool deck is not a surround around a pool at ground level; it is an elevated platform structure built up to the pool wall height, typically 900mm to 1,200mm above ground, providing a level access surface from which to enter the pool and a usable deck area around the pool perimeter.

Semi-inground fibreglass pools are particularly common in SA because they allow a pool to be installed on a sloped block or in ground conditions where a fully in-ground installation would be cost-prohibitive or structurally complex. The pool shell is set partially in and partially out of the ground, and the exposed above-ground section of the pool wall is typically clad or built into the deck structure so that the finished deck surface meets the pool coping at a comfortable entry height. The structural design of the deck wrapping around the above-ground portion of the pool shell must account for the loads the deck structure places on the pool shell, because an above-ground pool shell is not designed to have significant lateral loads applied against it by an adjacent deck frame. A gap between the deck sub-structure framing and the pool wall, bridged only by the deck boards themselves, is the correct structural approach rather than bearing the deck frame directly against the pool shell.

Above-ground pool decks in SA require pool barrier fencing just as in-ground pools do, but the barrier design often looks different because the pool wall itself, if high enough, can form part of the barrier. The pool must still be fenced so that a child cannot access the water from the deck without passing through a compliant self-closing gate, and the deck access stairs must incorporate a compliant gate at their base or top to prevent unsupervised child access to the elevated deck platform. Experienced SA pool deck builders who regularly work with above-ground and semi-inground pools understand these barrier integration requirements and design the deck structure and access configuration accordingly from the outset.

Surface Temperature and Barefoot Safety in SA Summer

Surface temperature safety on SA pool decks is a genuinely serious consideration that most decking content glosses over, and one that makes a real practical difference for families with young children. Adelaide's summer sun on a north or west-facing pool deck surface will heat dark-coloured deck materials to temperatures that are dangerous for small children's bare feet, not merely uncomfortable.

Research on surface temperatures in high-UV environments consistently shows that dark composite decking in full summer sun in a high-UV environment can reach 65 to 75 degrees Celsius on the exposed surface. Light-coloured composite decking in the same environment reaches 45 to 55 degrees. Timber deck boards typically run 5 to 10 degrees cooler than equivalent-colour composite due to the lower thermal conductivity of wood compared to the polymer and fibre composite. Concrete and ceramic pool paving reaches the highest surface temperatures of any pool surround material and is genuinely painful to walk across barefoot in SA summer conditions. For a pool deck in Adelaide that is used by young children during December through February, the practical guidance is clear: specify light-coloured materials, and if dark colours are selected for aesthetic reasons, ensure the pool deck layout includes shaded sections or light-coloured pathways that children can use to approach the pool without crossing hot dark surfaces.

Some composite decking manufacturers have developed heat-reduction technology specifically in response to this concern. Trex's CoolDeck technology and similar heat-reduction coatings in products from Ekodeck and Millboard use infra-red reflective pigments that reduce the surface temperature of darker colours by 10 to 15 degrees compared to standard composite products at the same colour value. This technology is worth specifically asking about when selecting composite decking for an SA pool surround, and builders who are familiar with the SA pool deck market will be aware of these product options. The cost premium for heat-reduction composite over standard composite is modest, typically 8 to 15 percent, and for families with young children in Adelaide the safety benefit more than justifies it.

SA UV and Chlorine Effects on Pool Decking

The specific combination of SA's UV exposure and pool chemical exposure creates a more demanding environment for pool deck materials than either factor alone would produce. UV degrades timber coating systems and degrades the UV stabilisers in composite decking products. Chlorine in pool water that splashes onto timber deck surfaces strips surface oils and can bleach the timber, and chlorinated water that pools in board gaps or against fixings accelerates corrosion of steel fasteners.

For timber pool decks in SA, the most effective protection strategy combines a quality penetrating oil specifically rated for pool surround exposure, stainless steel or hot-dipped galvanised fixings throughout, and prompt attention to any areas where the coating shows depletion before they are exposed to pool water without protection. Standard zinc-plated fasteners corrode noticeably faster in the pool surround environment than in standard outdoor deck applications, and the corrosion products stain the timber surface. Stainless steel fixings, while more expensive at purchase, are the correct specification for any SA pool deck that will have long-term service life expectations.

For composite pool decks in SA, the UV concern is managed by specifying products with integral UV stabilisers, which quality products from Trex, Millboard, and Ekodeck all include. Chlorine exposure does not cause the same coating degradation issues for composite products that it does for timber, because composite decking does not rely on a surface coating for its structural integrity. The primary maintenance task for composite pool decks is removing algae and biological growth from the board surface, particularly in shaded areas of the pool surround where moisture and limited UV create conditions for algal growth. Purpose-formulated composite deck cleaner removes these deposits effectively without damaging the composite surface. For the full range of composite deck options and their specific pool environment characteristics, our composite decking SA guide provides detailed guidance.

CBS SA Licensing Requirements

Pool decking construction in South Australia is building work and is subject to the CBS SA licensing requirements applicable to all building work. For pool decking projects above $12,000 in total value, which covers most medium and large pool surround projects, a CBS SA licensed building work contractor is required. Below $12,000, the licensing requirement does not technically apply, but given the safety implications of pool surrounds and the pool barrier compliance requirements, using a licensed contractor is strongly advisable for pool decking work at any project value.

The pool barrier compliance aspect of pool decking creates an additional compliance dimension. In South Australia, pool barriers must comply with the relevant building standards and should be inspected by a licensed building surveyor or private certifier to confirm compliance. When the pool deck forms part of or is adjacent to the pool barrier system, the deck construction directly affects the barrier compliance, and any changes to the deck that affect the barrier (such as raising the deck height to a level that creates a climbable element within 900mm of the barrier) can render the barrier non-compliant. Using a builder who understands pool barrier requirements and integrates them into the deck design from the outset avoids the risk of building a non-compliant pool surround. The CBS SA website provides licence verification tools and information on the applicable licensing categories for pool decking work across South Australia.

For pool decks that involve electrical work such as outdoor lighting, pool pump circuit connections, or pool equipment, all electrical work must be carried out by a licensed electrician under SA's electrical licensing requirements. Pool electrical work has specific requirements relating to the distance between electrical outlets and the pool water, the type of electrical protective devices required near pools, and the earthing requirements for pool equipment. These requirements are in the relevant Australian Standards and the SA Building Code, and a licensed electrician familiar with pool electrical requirements will design and install the pool electrical system to comply with them. For working at heights on elevated pool deck components or on Hills properties with significant elevation, SafeWork SA requirements for working safely at height apply.

Pool Decking Costs Across Adelaide

Adelaide metro pool decking pricing varies across the metropolitan area, with the eastern and Hills suburbs tending toward the higher end of the range due to the prevalence of premium pool installations and the more complex site conditions. Pool decking in coastal suburbs from Glenelg to Aldinga may involve specific soil conditions from proximity to the coast and the need for marine-grade fixings given the salt air environment. Northern suburbs installations generally offer the most competitive pricing due to good site access and a competitive local construction market.

Premium pool decking projects in the eastern suburbs and the Adelaide Hills frequently involve additional complexity that drives costs to the higher end of these ranges. This includes irregular pool shapes that require complex board cutting patterns, elevated deck structures on sloped Hills blocks, glass pool fencing rather than standard aluminium fence systems, and the integration of the pool deck with a broader outdoor entertaining area including kitchen benches, shade structures, and outdoor dining zones. For the full pricing context of deck and outdoor living area combinations, our deck and verandah SA guide covers the combined project costs in detail.

Pool Decking Costs in Regional SA

Regional SA pool decking follows the same cost structure as metropolitan Adelaide with the addition of tradesperson mobilisation costs in more remote areas and specific climate exposure considerations. The Fleurieu Peninsula, Barossa Valley, and Clare Valley all have established residential markets with active pool construction, and pool decking contractors serving these areas are experienced with the local conditions.

The Riverland is worth specific mention for pool decking because the extreme summer temperatures in this region mean that dark-coloured pool deck surfaces reach surface temperatures that genuinely challenge barefoot use. For Riverland pool surrounds, specifying a light-coloured composite product, a lighter-toned hardwood, or a timber treated and oiled with a light tone finish is particularly important for summer usability. Composite decking manufacturers' heat-reduction product lines are worth investigating for Riverland pool surrounds, as these products use specialist pigments and surface technology to reduce surface temperature compared to standard composite products at equivalent or near-equivalent colour appearances.

Maintenance for Pool Deck Environments

Pool surround decking maintenance requirements differ from standard garden deck maintenance because of the additional exposure to pool water and chemicals. For timber pool decks, the maintenance programme should include more frequent oiling than an open garden deck of equivalent timber species, because the moisture cycling from pool use depletes the surface oil faster. A realistic maintenance interval for a treated pine or hardwood pool surround in SA is six to twelve months, compared to one to three years for a garden deck of the same species.

Biological growth management is a specific and often underestimated maintenance challenge for SA pool surrounds, particularly in shaded sections. Algae and biofilm accumulate on pool deck surfaces in areas that stay damp and receive limited direct sunlight, and these biological films are the primary slip hazard on pool decks more often than inadequate initial surface texture. A deck that passes the AS 4586 P4 slip resistance classification when new can effectively fall below that threshold in practice when it carries a thin film of algae or biofilm that reduces the coefficient of friction between the surface and a wet foot. For the Adelaide Hills, south-facing pool decks, and any deck areas shaded by structures, trees, or fencing, algae management is not an optional extra: it is a regular maintenance requirement.

For timber pool decks, a dilute solution of sodium hypochlorite (1 part household bleach to 10 parts water) applied to the affected area and allowed to dwell for 10 to 15 minutes before scrubbing and rinsing effectively kills algae and biofilm without damaging the timber when used at appropriate dilution. More aggressive concentrations bleach the timber and should be avoided. Purpose-formulated biological growth removers from brands including Wet and Forget and Rapid Clean are less aggressive and can be applied and left to act on the surface over several days without rinsing, making them practical for regular preventive treatment on areas prone to growth. For composite pool decks, always check the manufacturer's approved cleaning products before using bleach solutions, as some composite formulations are sensitive to chlorine-based cleaners at concentrations above those approved by the manufacturer.

For holiday and seasonal properties with pools that are not in year-round use, the off-season care of timber pool decking is worth planning specifically. A timber pool deck that sits dormant through a wet Adelaide winter without maintenance is subject to more moisture cycling and biological growth than an actively used deck, because pool use itself involves regular drying cycles that inhibit growth. Before covering the pool for winter, apply a maintenance oil coat to the deck surface so the timber goes into the off-season protected rather than already depleted. Clear the board gaps of debris that would hold moisture, and if the deck is covered by a shade sail or other structure in winter, ensure adequate ventilation beneath the cover to prevent moisture accumulation. Returning to the deck at the start of the swim season, inspect and address any biological growth before the first pool use of the season when the deck will see peak barefoot traffic. Post your pool decking project on The Quote Yard to connect with licensed SA pool deck builders across Adelaide and regional South Australia. For pool barrier compliance requirements and inspections, contact the relevant local council or a licensed building certifier. The South Australian Civil and Administrative Tribunal (SACAT) provides dispute resolution for building and construction work in SA. The Standards Australia framework through AS 4586 governs slip resistance requirements for pool surround surfaces.

What to Look For in Pool Decking Quotes

A quality pool decking quote in SA should specify the deck board material, species or product name, treatment class for timber, slip resistance classification for the specific product, fixing specification, sub-structure species and treatment class, footing design approach, pool barrier integration design, and the planning and building consent strategy. It should also address whether the barrier fencing is included in the quoted scope or whether it is a separate contract, and what the approach is for certifying the pool barrier compliance after construction.

Ask specifically about the slip resistance classification of the decking product being proposed and confirm it meets the AS 4586 P4 requirement for pool surrounds. Ask about the fixing specification and confirm that stainless steel or hot-dipped galvanised fixings are being used rather than standard zinc-plated fasteners. Ask how the junction between the deck and the pool coping will be detailed and whether there is a specific waterproofing or sealing approach at this junction to prevent water from tracking into the sub-structure. Ask how drainage under the deck has been designed and how water pooling beneath the structure will be prevented.

Also ask whether the builder has experience with the pool barrier requirements applicable to SA residential pools and whether they have built pool decks that have passed barrier inspections in similar configurations. A builder who is vague about pool barrier requirements or who says the barrier compliance is the client's responsibility to organise separately is not taking full responsibility for the integrated design of the pool deck and barrier system. The pool deck and the pool barrier need to be designed as an integrated system, and accountability for that integration should sit with the building contractor managing the project. Verify CBS SA registration through the CBS SA website before signing a pool decking contract. The ACCC consumer guarantee framework applies to building and construction services in SA and provides homeowners with recourse if a pool deck project fails to meet reasonable quality expectations.
