Patent

CA 2504658

An improved block paving sand comprising kiln dried sand mixed with a water- soluble polymer. The block paving sand is filled into gaps between blocks and then water is applied thereto. Upon contact with the water, the polymer coats the sand and then sets hard, thereby stabilising the block paving.

L'invention concerne un sable amélioré pour pavage comprenant un sable séché au four mélangé avec un polymère soluble dans l'eau. Ledit sable pour pavage amélioré remplit des espacements entre des blocs et l'eau est ensuite versée sur ce dernier. Après la mise en contact avec l'eau, le polymère couvre le sable et se solidifie tout en stabilisant le pavage.
