Resin-bound surfacing — technical data

Addaflex R

Resin bound rubber stone surfacing

Manufacturer Addagrip Terraco Ltd
Country of origin United Kingdom
System family Resin-bound surfacing

The product

A pale brown polyurethane resin binding natural aggregate with recycled rubber tyre chippings — a softer, more forgiving surface where a degree of give matters. The resin darkens under UV.

Where it is used

  • Play and recreation surfaces
  • Pedestrian areas needing a softer surface
  • Landscape paths

Substrates

  • Asphalt or concrete at 25 mm laid depth
  • Compacted stone at 30 mm laid depth

Application data

Coverage, thickness, mix and cure, as declared by the manufacturer. Site conditions in the Gulf sit at the top of most of these ranges — allow for it in the programme.
