The Delgorsa® kerbing corners derive from the sawing, shaping and subsequent flaming of the visible edges of the blocks (for at least 15 cm). Almost always used in pairs, at the extremities of a driveway, they remind us of the kerbs leading to the access path.
The Delgorsa® overflow drains derive from extra-thick slabs obtained through the sawing, shaping and subsequent bush hammering of the surface, creating a concavity of at least 2 cm on the slab length to collect rainwater.
