HydroKerb is particularly suited to areas where depth is limited due to existing services or where space/ location demands that the existing kerb line is maintained.

The system comprises a channel base unit and a British Standard profile kerb incorporating drainage holes. The units are laid to a fall.

HydroKerb bases are manufactured from high quality quartzite and granite, bound in a resin compound. The tops are manufactured from South West granites, using a wet pressed method, the kerb is then shot blasted to expose the aggregate.
