Andesite · Sawn (raw) / Sandblasted
Andesite Kerbstone
Light-grey kerbs to match andesite paving.
Andesite kerbstones are sawn to the same road profiles as our basalt kerbs and combine naturally with andesite paving or provide a contrast to dark basalt. They resist frost and road salt; radius pieces are made on request.
- Matches andesite paving
- Frost and road salt resistant
- Radius and chamfered pieces to order
- Available finishes
- Sawn (raw), Sandblasted
- Applications
- Kerbs & urban infrastructureLandscape & garden
Custom sizes, thicknesses, profiles and mixed finishes are produced to order from your drawings.
