Resin-bound paving

Resin-bound paving is a permeable surfacing system in which clean stone aggregate is mixed with a clear polyurethane or epoxy resin and trowel-applied over a porous base. The finished surface allows rainwater to drain through the binder matrix into a sub-base, supporting SuDS objectives under Building Regulations Part H3 and London Plan policies. The system is widely used for driveways, paths and entrance courts across Greater London because it can be laid in front gardens without planning permission, provided drainage design is appropriate. Resin-bound surfaces are identifiable by their smooth, decorative finish with visible aggregate particles bound in a glossy matrix. Common defects include localised loss of permeability where surface contamination has clogged the matrix, and resin yellowing under prolonged UV exposure. Patch repair is generally feasible for small damaged areas.
