Anti-Slip Decking Inserts & Retrofit Safety Products
GripDeck® retrofit products are designed to improve grip on existing timber decking, steps, stairs, ramps, walkways and access routes without always needing to replace the whole surface. The range includes RetroGrip® anti-slip decking inserts, decking strips, stair nosings, anti-slip treads, Stadia Strips and GRP products.
Whether you need to stop decking being slippery, improve grip on timber steps, add a visible anti-slip stair nosing or provide heavy-duty GRP stair treads, GripDeck® can help you choose a suitable retrofit anti-slip solution.
Which Product Stops Slippery Decking?
If your existing grooved timber decking is sound and stable, RetroGrip® decking inserts may be suitable. If the surface is damaged, rotten, loose or unsuitable for retrofit, replacement with GripDeck® anti-slip timber decking may be the safer long-term option.
For steps, ramps, industrial access routes and high-footfall areas, anti-slip stair nosings, treads, Stadia Strips or GRP covers may be more appropriate than standard decking inserts.

View WarrantyCheck Your Existing Surface First
Before choosing anti-slip decking inserts, decking grip strips or any other retrofit product, check that the existing decking, step or access surface is suitable. Retrofit products should only be installed onto sound, stable and compatible surfaces.
Is the Timber Sound?
Rotten, split, loose or heavily damaged decking should usually be repaired or replaced before any retrofit product is installed.
Is the Groove Suitable?
RetroGrip® inserts are designed for suitable grooved timber decking. Groove size and condition should be checked before ordering.
Is the Area High Risk?
Steps, ramps, shaded areas and wet access routes may require a more robust product such as treads, nosings, Stadia Strips or GRP.
RetroGrip® Inserts vs Replacement Decking
| Option | Best For | Considerations |
|---|---|---|
| RetroGrip® decking inserts | Existing grooved timber decking that is structurally sound but slippery. | Often quicker and lower cost than full replacement. |
| Replacement GripDeck® decking | Decking that is rotten, unstable, badly damaged or unsuitable for retrofit inserts. | Best long-term option if the existing boards are no longer serviceable. |
| GRP stair treads and covers | Steps, ramps, industrial access routes and higher-risk surfaces. | Can offer a robust retrofit surface for demanding environments. |
