Basalt Kerbstone

Heavy-duty kerbs for roads, car parks and landscaping.

Basalt kerbstones are sawn from solid blocks to standard road profiles. Their density and low water absorption make them far more durable than concrete kerbs in freezing climates and under de-icing salt. Chamfered, bullnosed and radius kerbs are produced to order.

  • Frost and de-icing salt resistant
  • Standard road profiles, custom radius pieces
  • Sawn or sandblasted top surface
Available finishes
Sawn (raw), Sandblasted

Custom sizes, thicknesses, profiles and mixed finishes are produced to order from your drawings.
