Basalt kerbs are made from blocks of stone. The main processing is hammering sawn sides with bevel, but other finishes are also possible. Basalt kerbs can also be made by mechanical splitting, finishing with severing or rifling. Kerbs can be produced with different curvature radii or with cuts (vents) used for the drainage of water. When laid vertically kerbs are used for the formation of pavements, flower beds and for the delimitation of paved areas. When used as risers to connect various walking surfaces along stairways the aesthetic result that is obtained is enhanced by the contemporary functional significance that facilitates vision when changing levels, with huge strong points for pedestrians. They can be combined with other products of the same material or associated with other stones allowing considerable freedom of aesthetic choice.
