Port Stephens has a significant and growing aged population, with many retirees and semi-retirees living in the region’s coastal communities. As mobility needs change over time, the concrete around the home becomes a genuine safety and access issue. A cracked path, a slippery step, or a missing ramp connection between levels can mean the difference between a person remaining safely in their home or requiring a higher level of care.
This guide covers what concrete resurfacing and modification work can do to improve accessibility for older residents and people with disability, the standards that apply, and the practical options available in Port Stephens.
Who This Guide Is For
- Homeowners or their families adapting a property for an older resident
- Aged care facility managers overseeing external path and courtyard maintenance
- NDIS plan managers overseeing home modification funding for clients
- Property developers or builders ensuring new or modified homes meet accessible design standards
- Holiday rental owners who want to make their property suitable for mobility-impaired guests
The Accessibility Concrete Basics
Under the National Construction Code (NCC) and the Design for Access and Mobility standard AS 1428, certain properties must meet specific accessibility requirements. For private homes, these are triggered when:
- A new building is constructed (Class 1b, accommodation for the public, or Class 3, residential aged care)
- A building approval is sought for renovations that include accessible features
- NDIS Home Modification funding is being used (the funded modifications must meet AS 1428)
For existing private homes where the owner is self-funding modifications, AS 1428 is a best-practice guide rather than a mandatory requirement, but it provides an excellent framework for what works and what does not.
Key Accessibility Concerns That Concrete Work Can Address
1. Path Surface Condition
A cracked, uneven path is a trip hazard for anyone, but particularly for people using walking frames, wheelchairs, or who have reduced balance. The relevant issues:
- Crack lips: Where one side of a crack has risen above the other (even 5-10 mm differential), this is a trip hazard and a barrier to wheelchair wheels
- Surface deterioration: Spalling or eroded surfaces create an irregular surface that catches on mobility aids
- Slope variations: Paths that have settled unevenly have localised grade changes that can be dangerous for people with balance issues
Concrete solution: Diamond grinding to remove crack lips and surface irregularities; polymer overlay to create a flat, even surface; penetrating sealer to prevent future salt damage and maintain surface consistency.
2. Path Width
AS 1428 requires accessible paths to be a minimum of 1000 mm clear width (1200 mm preferred) to accommodate a wheelchair. Existing paths in Port Stephens homes built pre-1990 are often 600-900 mm, too narrow for wheelchair access.
Concrete solution: Path widening requires forming and pouring additional concrete beside the existing path, then resurfacing both old and new sections together for a consistent finish. This is a combined concreting and resurfacing project.
3. Non-Slip Surface Performance
For mobility-impaired individuals, particularly those using walking aids or with reduced gait control, a slippery surface is extremely hazardous. AS 1428 requires a slip resistance classification of P3 minimum (dry conditions) and P4 in wet areas.
Port Stephens homes with coastal-facing paths, pool-adjacent paths, and external steps need particular attention to non-slip treatment because these surfaces are regularly wet.
Concrete solution: Any new or resurfaced path should include an anti-slip surface treatment. Options include:
- Fine aggregate broadcast into a wet sealer coat (economical, practical)
- Textured spray-on overlay (provides inherent texture)
- Anti-slip additive mixed into the topcoat
- Fine diamond grinding to restore surface texture to worn smooth concrete
| Area | Recommended Minimum Slip Rating | Treatment |
|---|---|---|
| External paths (covered) | P3 | Anti-slip additive in sealer |
| External paths (exposed) | P4 | Aggregate broadcast or textured overlay |
| Ramp surfaces | P4 | Aggregate broadcast |
| Step treads | P4 | Aggregate broadcast |
| Wet areas (pool surround, amenities) | P4, P5 | Aggregate broadcast |
4. Access Ramps
Steps are the most significant access barrier for wheelchair users, people using walking frames, and those with reduced leg strength. Installing a concrete ramp (or resurfacing an existing ramp) alongside or replacing steps requires:
Gradient: Maximum 1:14 (for unaided use); 1:20 preferred; maximum 1:8 for assisted access only. For NDIS-funded modifications, 1:14 is the standard.
Width: Minimum 1000 mm clear; 1200 mm preferred.
Surface: Non-slip finish, P4 classification minimum.
Landings: At the top and bottom of each ramp, minimum 1200 mm x 1200 mm, free of trip hazards.
Edge protection: Kerb or raised edge on open sides to prevent mobility aids running off the ramp edge.
An experienced concrete contractor can form and pour a compliant ramp alongside an existing stair and resurface the combined stair/ramp arrangement to a consistent, non-slip finish.
5. Level Thresholds
Where concrete paths meet doorways, any threshold height difference above 5 mm is a barrier for wheeled mobility aids. Port Stephens homes with external-to-internal level transitions sometimes have 20-40 mm steps at doorways.
Concrete solution: Adding a small concrete transition ramp (a “lipstick ramp”) to bridge the threshold is typically a small concreting job, achievable as part of a broader path resurfacing project.
6. Edges and Bollards
Paths with unprotected edges adjacent to drops or planted areas benefit from edge treatment, low kerbs or surface marking strips, to guide mobility aids. Tactile ground surface indicators (TGSIs) can be set into concrete surfaces at hazard points for vision-impaired users.
Aged Care Facility External Areas
For residential aged care facilities in Port Stephens, several of which serve the Raymond Terrace and Nelson Bay communities, external courtyard and path maintenance is a regulatory obligation under the Aged Care Quality and Safety Commission framework. Relevant requirements:
- External paths must be safe for unaided and aided mobility as appropriate to resident capability
- Non-slip surfaces must be maintained, annual inspection and record-keeping is good practice
- Drainage must prevent pooling that creates trip hazards and wet surfaces
- Any trip hazards (cracked concrete, roots, level changes) must be promptly addressed
A scheduled resurfacing and maintenance programme for aged care facility concrete is more cost-effective and regulatorily compliant than reactive individual repairs.
NDIS Home Modifications and Concrete Work
The NDIS funds Assistive Technology and Home Modifications for eligible participants. Concrete resurfacing and access ramp construction falls under the Home Modification category. Eligibility requires:
- NDIS participant with a support need for mobility or access
- Recommendation from an Occupational Therapist (OT) assessing the home
- Quotes from registered builders or contractors for the proposed works
As of 2026, home modifications up to $20,000 can be approved through the OT recommendation pathway; above this threshold, additional assessment is required.
Written quotes suitable for NDIS home modification funding applications are the contractor’s to provide, and they’re a reasonable thing to ask for. Contact us with the OT recommendation; if and when an independent contractor is confirmed for your area, your enquiry is referred with that context so they can quote to it.

Frequently Asked Questions
Can I resurface an existing path to make it wheelchair-accessible without replacing it? In many cases yes, if the path is wide enough (1000 mm minimum) and the surface condition can be restored to flat and even, a polymer overlay with non-slip aggregate surface provides an accessible result. If the path has significant level differentials (crack lips, settled sections more than 10 mm differential), grinding to level and then overlaying is required.
Does NDIS cover concrete resurfacing for accessibility improvements? Yes, if the work is recommended by an Occupational Therapist as a home modification necessary to support the participant’s independence and mobility. The funded works must be carried out by a licensed contractor and meet applicable Australian standards.
What slip resistance rating do I need for an outdoor ramp? P4 minimum for a self-use outdoor access ramp, as per AS 1428.1. This requires a pendulum test value (PTV) of 36-54 in wet conditions. A properly textured spray-on overlay or aggregate broadcast system achieves P4 consistently.
How long does it take to install a concrete access ramp? A standard residential access ramp can be formed and poured in one day and is ready for use after 48-72 hours curing. Larger or more complex projects take longer. If the ramp is part of a broader path resurfacing project, the work can usually be completed in a single visit.
Can you add tactile surface indicators (TGSI) to new or existing concrete? Yes. TGSIs, the raised dome or bar tactile tiles used at hazard points, are available as surface-applied adhesive-fixed units suitable for concrete paths. These can be added to new overlays or existing concrete surfaces. They’re installed as part of an accessibility upgrade project.
