Pool surrounds are one of the highest-risk surfaces for slips and falls in residential settings. Water, sunscreen, bare feet, and running children create conditions that demand surfaces with verified slip resistance, not just surfaces that feel rough enough. NSW has specific requirements that apply to pool surrounds, and understanding them is important both for new pool construction and for resurfacing existing pool areas.
This guide covers the specific Australian Standard that applies, what classification pool surrounds must achieve, how compliance is tested and documented, and how Port Stephens property owners can bring non-compliant pool surrounds into compliance efficiently.
The Applicable Standard: AS 4586-2013
Australian Standard AS 4586-2013 (Slip resistance classification of new pedestrian surface materials) is the primary document governing slip resistance in Australia. It uses a pendulum test (measuring Dynamic Coefficient of Friction, or DCoF) to classify surfaces into P ratings:
| Classification | Pendulum Test Value (PTV) | Application |
|---|---|---|
| P0 | < 12 | Not recommended for pedestrian areas |
| P1 | 12-24 | Low risk, dry conditions only |
| P2 | 25-35 | Low risk wet, or high risk dry |
| P3 | 36-54 | Moderate wet risk |
| P4 | 36-54 (wet pendulum) | High risk wet areas, pool surrounds minimum |
| P5 | 54+ (wet pendulum) | Very high risk wet areas |
For pool surrounds specifically, P4 is the minimum required classification under the National Construction Code (NCC) and as referenced in relevant Australian standards for swimming pool barriers and surrounds.
What NSW Requirements Apply to Pool Surrounds
For new pool construction in NSW: The National Construction Code (NCC 2022) requires pool surrounds to have a minimum wet slip resistance classification of P4. This applies to all new pool construction requiring development approval.
For existing pools: There is no mandatory retrofit requirement for existing pools to meet current standards, but property owners have a common-law duty of care to visitors and guests. In a holiday rental property or aged care context, the duty of care argument is particularly strong.
For commercial pools: Hotels, motels, and holiday parks with pools must comply with current NCC requirements and maintain compliance through the pool’s operational life. Regular re-testing and certification is best practice for commercial operators.
NSW Building Code: The Building Code of Australia (BCA), which forms part of the NCC, requires accessible paths to pool areas to comply with AS 1428 accessibility requirements as well as AS 4586 slip resistance.
How Slip Resistance Is Tested
Pendulum Test (AS 4586 Method)
The definitive test uses a pendulum device with a standardised rubber slider that swings across the wet surface and measures the friction force. The Pendulum Test Value (PTV) is recorded, and the surface is classified P0, P5 accordingly.
- Tests must be conducted by a qualified tester
- Results are recorded and a certificate is issued
- Testing must be conducted in wet conditions (water or pool water applied to the surface)
- Testing should reflect the installed surface condition, not the product specification
Ramp Test (AS 4586 Method B)
For some surface types, a ramp test (measuring the angle at which a person in standardised footwear begins to slip) is used instead of the pendulum test. This is more common for testing flooring materials before installation.
Portable Tribometer (Useful but Not the Primary Test)
For site inspections, portable tribometers (BOT-3000, Tortus) can give useful field readings but are not the primary certification method under AS 4586. They are useful for condition monitoring and indicating whether a surface is likely to pass or fail the pendulum test.
Common Pool Surround Materials and Their Typical Classification
| Material | Typical Classification (Wet) | Notes |
|---|---|---|
| Smooth glazed ceramic tile | P1, P2 | Dangerously slippery when wet, must be replaced or overlaid |
| Old pebblecrete | P3, P4 (new); P2, P3 (worn) | Degrades with age; re-testing needed for older pebblecrete |
| New pebblecrete (sand seeded) | P4, P5 | Good inherent slip resistance |
| Brushed/broom concrete | P3, P4 | Depends on aggregate and brush texture |
| Exposed aggregate overlay | P4, P5 | Good inherent slip resistance |
| Spray-on overlay (no aggregate) | P2, P3 | May not achieve P4 without anti-slip additive |
| Spray-on overlay + anti-slip aggregate | P4, P5 | Appropriate for pool surrounds |
| Epoxy + aluminium oxide broadcast | P5 | Commercial pool surrounds |
Achieving P4 Compliance When Resurfacing
When resurfacing a Port Stephens pool surround, specify a system that will achieve P4 classification. The most reliable approaches:
Option 1: Exposed aggregate spray-on overlay The aggregate exposed in the surface provides inherent friction. River pebble or quartz aggregate systems consistently achieve P4. No additional anti-slip additive required.
Option 2: Spray-on overlay + aggregate broadcast Apply a polymer overlay in the normal manner, then broadcast fine quartz or aluminium oxide aggregate into the wet topcoat before it cures. Aluminium oxide broadcast reliably achieves P5; fine quartz typically achieves P4.
Option 3: New pebblecrete surface Traditional pebblecrete (seeded pebble aggregate in a cement matrix) achieves P4, P5 inherently. For Port Stephens pools, this is a familiar and well-proven choice. See our guide: Pebblecrete Pool Surrounds.
Option 4: Epoxy system with aggregate For commercial pool surrounds (hotels, holiday parks), a two-pack epoxy with aluminium oxide aggregate broadcast achieves P5 and provides excellent chemical resistance to pool chemicals.
Getting a Compliance Certificate
For property owners who need documented proof of slip resistance compliance:
- Specify the product: When engaging a resurfacing contractor, ensure the specification includes the target P classification and the system to achieve it.
- Have the finished surface tested: Engage an accredited slip resistance tester to perform the wet pendulum test after resurfacing is complete.
- Receive a certificate: The tester provides a written certificate showing the PTV achieved and the resulting P classification.
- Retain on file: Keep the certificate with your property records. For commercial properties, this forms part of your WH&S file.
Accredited slip resistance testers work across Port Stephens, and testing can be coordinated as part of a pool resurfacing project. Contact us to discuss.
Holiday Rental Pools in Port Stephens: Compliance Matters More Than You Think
Port Stephens has a very high density of holiday rental properties with pools, Nelson Bay, Anna Bay, Shoal Bay, and Fingal Bay all have numerous holiday homes with pools. In this context:
- Guests are unfamiliar with the property, they may not know which areas are slippery or where the pool access points are
- Alcohol is frequently consumed at holiday rental pools, a significant factor in pool surround slip events
- Children are common guests, and have less risk awareness around wet pool areas
A P4-compliant pool surround in a Port Stephens holiday rental is both a genuine safety measure and a liability protection strategy. If a guest is injured on a non-compliant pool surround, the lack of compliance could be a significant factor in any insurance or legal proceedings.
Checking and Maintaining Existing Pool Surrounds
Slip resistance is not permanent. It degrades as the surface wears. Checking factors:
- Do a practical assessment: Walk the wet pool surround in bare feet. If it feels slippery in any zone, have it tested.
- Check for worn areas: Areas with heavy traffic (step entry points, outside shower areas) wear faster than the main pool deck.
- Check for algae or biological growth: Even a thin film of algae dramatically reduces slip resistance. Pool surrounds with regular algae growth should be cleaned monthly and inspected for slip resistance seasonally.
Schedule formal retesting every 5-7 years, or whenever the surface condition changes significantly.

Frequently Asked Questions
Is my existing pool surround required by law to comply with AS 4586? For pools built before 2004 (when slip resistance standards were incorporated into the BCA), there is no retrospective mandatory requirement for private residential pools. However, duty of care under common law applies, and for commercial properties and holiday rentals, the standard should be treated as effectively mandatory from a liability perspective.
How do I know what classification my existing pool surround achieves? The only way to know with certainty is to have a wet pendulum test performed by an accredited tester. A visual or touch assessment is indicative only. Old pebblecrete that has worn smooth may feel adequate but test below P4.
My pool surround is old pebblecrete, does it need replacing or can it be resurfaced? If structurally sound (no cracking, no hollow areas, aggregate still well embedded), old pebblecrete can usually be resurfaced with a new pebblecrete or exposed aggregate overlay system, bringing it back to P4 classification without full replacement. This is significantly cheaper than replacement.
Can I do a slip resistance test myself? You cannot conduct a formal AS 4586 pendulum test without the equipment. However, a portable field test using water and a simple assessment (wet the surface, walk on it, observe) gives a good practical sense of whether the surface is dangerously slippery. For formal documentation, engage an accredited tester.
What is the cost of a formal slip resistance test in Port Stephens? A single-site pendulum test from an accredited tester typically costs $300 to $600 including a written certificate. This is a minor cost relative to the value of the compliance documentation and the cost of the resurfacing work it certifies.
