Not all resin driveways are the same. The terms resin bound and resin bonded are often confused, but only one of them provides true permeability.
Resin bound driveways mix resin and aggregate together before installation. This creates a smooth, porous surface where water can pass through small gaps between stones.
Resin bonded systems, on the other hand, involve applying resin to a base layer and scattering stones on top. This creates a sealed surface that behaves more like concrete or tarmac, meaning water runs off rather than draining through.
