Description

The traficked upper face of COMCON VL slabs is provided with grooves of trapezoidal cross section in accordance with the requirements of the United Association of Blind Citizens. The grooves are so arranged in a single direction that the trapezoidal projections are spaced 25 mm at centres. They are 15 mm wide and their lower base is 10 mm wide. One slab 400 mm wide has 16 grooves. The slab surface (both projections and depressions) is smooth, but not slippery. The customary colour is dark grey, but the manufacture of slabs of other colour (white, black, brown etc.) is no problem. The colour is achieved by inorganic pigments mixed with the mass, as a result of which it is permanent and dispenses with any maintenance or periodic repainting throughout its whole service life.

The COMCON VL slabs are placed in a lean cement mortar bed spread on top of a well compacted base course. The slabs are intended for pedestrian traffic. If well placed on a stiff base course along their whole area, they will not be damaged by light-weight delivery vans or passenger cars.
