What is resin bonded surfacing?

Resin bonded surfacing applies a scatter coat of loose aggregate stone directly onto a thin layer of resin adhesive. The resin glues the aggregate in place while leaving the stone exposed at the surface, creating a textured finish with visible chip colours and sizes.

This system differs from resin bound, where aggregate is mixed throughout a thicker resin layer before application. Resin bonded uses less resin overall and allows water to drain through the gaps between the loose stones, making it a permeable surface. This drainage property matters for Cheltenham properties subject to flood risk assessments or where sustainable drainage is required.

The scattered aggregate approach gives resin bonded a coarser, more pronounced texture than resin bound. Surface feel underfoot is rougher, and the finish can appear flecked or speckled depending on stone choice. Because aggregate sits loosely rather than fully bound, resin bonded surfaces can shed small stones under heavy traffic or foot wear, particularly on steep slopes or in high-traffic areas.

Resin bonded works on existing concrete or asphalt bases and is often chosen for driveways and paths where permeability, cost, and visual texture matter equally. It requires proper base preparation and appropriate resin choice for Cheltenham's climate.
