Pool Surround Decking: The Complete Australian Guide

Your pool surround is one of the hardest-working surfaces in your home. It needs to look beautiful, stay safe when wet, handle constant moisture and chemical exposure, stay cool enough to walk on barefoot in summer, and require as little maintenance as possible. That's a demanding brief — and not every decking material is up to the job.

This guide covers everything you need to know to choose the right pool surround decking for your Australian home.

The Unique Demands of Pool Surround Decking

Pool surrounds face conditions that no other outdoor surface has to deal with simultaneously:

• Constant moisture: Splashing, wet feet, and rain mean the surface is frequently wet
• Chemical exposure: Pool chlorine and salt water are corrosive to many materials
• Intense UV: Pool areas are typically open and exposed to full sun for most of the day
• Heat retention: Dark or dense surfaces can become dangerously hot underfoot in Australian summer
• Slip risk: A wet pool surround is a high-risk slip zone — particularly for children
• Barefoot comfort: The surface needs to be splinter-free and comfortable to walk on without footwear

Any material you choose for your pool surround needs to perform across all of these dimensions — not just one or two.

Pool Surround Material Options: Compared

Composite Decking

Composite decking has become the most popular pool surround choice for Australian homeowners — and for good reason. It ticks virtually every box for pool surround performance.

Pros:

• Splinter-free — essential for bare feet around pools
• Moisture and rot resistant — won't swell, warp, or deteriorate with constant water exposure
• Slip-resistant surface texture — most composite boards have a brushed or embossed finish that provides grip when wet
• Chemical resistant — handles chlorine and salt water without degrading
• UV stabilised — won't fade or bleach in full sun
• Low heat retention — lighter-coloured composite boards stay significantly cooler than stone or concrete in summer
• Low maintenance — no oiling, sealing, or repainting required
• Beautiful timber-look aesthetic that complements pool landscaping

Cons:

• Higher upfront cost than basic concrete or pavers
• Quality varies between brands — choose co-extrusion composite for pool environments

THQ recommendation: Co-extrusion composite decking is the premium choice for pool surrounds. The 4-sided polymer capping provides maximum moisture resistance and ensures the boards won't absorb water or harbour mould over time.

Hardwood Timber Decking

Timber has long been used around pools, and hardwoods like Merbau and Spotted Gum can look stunning in the right setting. However, timber around pools comes with significant drawbacks.

Pros: Natural aesthetic, can be refinished

Cons:

• Splinters — a serious hazard around pools, particularly for children
• Requires oiling every 6–12 months to maintain moisture resistance
• Chlorine and salt water accelerate surface degradation
• Can become slippery when wet if not properly maintained
• High ongoing maintenance cost

Verdict: Timber can work around pools but requires significant ongoing commitment. For most Australian homeowners, composite is the smarter long-term choice.

Travertine and Natural Stone

Travertine pavers are a popular premium pool surround option, offering a luxurious, resort-style aesthetic.

Pros: Premium look, naturally cool underfoot, durable

Cons:

• Porous — requires sealing and can harbour algae and mould if not maintained
• Heavy — requires a solid base and professional installation
• Can be slippery when wet depending on finish
• High cost for quality stone
• Cold in winter, though this is less of an issue in most Australian climates

Concrete and Exposed Aggregate

Concrete is the most affordable pool surround option and is widely used in budget pool builds.

Pros: Low upfront cost, durable, wide range of finishes

Cons:

• Can become extremely hot in Australian summer — a real safety concern for bare feet
• Rough exposed aggregate can be uncomfortable and abrasive on bare feet
• Cracks over time and can be difficult to repair seamlessly
• Limited aesthetic appeal compared to timber-look composite or stone

Slip Resistance: What You Need to Know

Slip resistance is non-negotiable for pool surrounds. In Australia, pool surrounds are classified as a wet area and should meet a minimum slip resistance rating of P4 or R11 under Australian Standard AS 4586.

When selecting composite decking for your pool surround, always confirm the slip resistance rating with your supplier. THQ's composite decking range features a brushed, embossed surface texture specifically designed to provide grip in wet conditions.

Heat Retention: Keeping Your Pool Surround Comfortable

In Australian summer, dark or dense surfaces can reach temperatures of 60–70°C in direct sun — hot enough to cause burns on bare feet. This is a critical consideration for pool surrounds where children and adults will be walking barefoot.

Coolest options: Light-coloured composite decking, travertine (naturally cool due to low thermal mass)

Hottest options: Dark concrete, dark stone, dark composite boards

Tip: If you love the look of darker decking colours, choose a board with a lighter base tone or consider a mid-tone colour that balances aesthetics with heat performance.
