Basalt curb stones are construction elements manufactured from basalt with different size and cuts for separating pavements and traffic islands and to direct rainwater to the sewage system. Basalt curb is divided as crushed stone and cut curb stone. Crushed curb stones are used in natural form without any processing. Cut curb stones are cut and shaped by water-jet cut during stone.
Crushed curb stones are generally lined to each side of garden walking paths while cut curb stones are mainly preferred in road divisions and road-sides.
