Basalt Water Channel
Solid basalt drainage channels and gutters for streets and squares.
Water channels are milled from solid basalt with a concave gutter profile to carry surface water along streets, squares and building perimeters. They match our kerbstones and paving, so the whole hardscape can be delivered from one source in one colour.
- Milled from solid blocks
- Matches kerbs and paving
- Custom profiles for drainage grates
- Available finishes
- Sawn (raw)
Custom sizes, thicknesses, profiles and mixed finishes are produced to order from your drawings.
