Resin bound surfacing is porous. When it is laid on a permeable base, rainwater passes straight through the surface and into the ground, which is why it is often specified as part of a sustainable drainage (SuDS) design.
The base matters most
A permeable resin bound surface needs a permeable base beneath it, usually open graded asphalt or a suitable concrete, over a free draining sub base. Laying resin bound onto a sealed base will still give a smooth finish, but the water has nowhere to go.
Where it works best
Footpaths, cycleways, courtyards, tree pits, school playgrounds and residential driveways all suit resin bound surfacing. It is less suited to areas with heavy turning traffic, where block paving or tarmac is usually the better option.
Why approved installers matter
Resin bound is mixed and trowelled on site, so the quality depends on the mix ratio, depth, weather and curing. As Daltex approved installers we follow the system guidance so the surface stays bonded and keeps its colour.
