The polymeric sand is an unique mixture of polymers added and calibrated sand of grey colour. It is easy to use, even for the most inexperienced, the polymeric sand offers the possibility to level the paving in a rapid way and with a sure result. The polymeric sand, in contact with the water, becomes very solid and it blocks up the grooves between the bricks, maintaining the paving fixed on the spot. The use of the polymeric sand is recommended for the swimming pools outlines, paths, pavements, patios and ramps of garages. It helps to prevent the growth of weeds, the damages caused from the insects and the erosions caused from the rain. Never to use the polymeric sand when the paving is laid on concrete surfaces.
