If you’ve already laid decking, or want to add our grip technology into your timber, then we offer a variety of retrofit GripDeck® products which can be bought from a number of UK suppliers or direct from GripDeck. RetroGrip anti-slip decking inserts are an award winning system that fits with most standard grooved decking; StadiaStrip is a heavier duty non-slip insert for timber or concrete; and GRP are our glass reinforced plastics which are ideal for making any slippery surface safe to walk on.
