Grasscrete is a cast-on-site cellular reinforced concrete paving system made from concrete with voids formed by styrene moulds, designed for permeable surfacing in trafficked and water management areas. Distinct from precast blocks, it supports up to 40 tonnes gross vehicle weight and provides optimal drainage.

  • Cast on site system for permeable surfacing with high loadbearing capacity

  • Withstands loads up to 40 tonnes gross vehicle weight

  • Reduces required sub-base depth and resists differential settlement

  • Self-venting structure tested to flow rates exceeding 8m per second

  • Eliminates need for kerb edges

  • Lightweight void formers improve shipping efficiency and lower carbon footprint

Applications

  • Vehicle parking for daily or overspill use

  • Emergency access

  • Maintenance access

  • Highway verges and pull-ins

  • Reservoirs and spillways

  • Storm/drainage channels, river and sea defences, swales
