In this invention, after the grade at a construction site has been excavated and/or graded to its preliminary rough grade, re-enforcing material, typically synthetic in nature, such as nylon or polypropylene mesh or rods, fibre-glass rods or mesh, or other specified re~enforcing material is laid across soil at the construction site and a reinforced base is formed by covering the reinforcing material with a polymeric resin, whereby upon curing, the polymeric resin and reinforcing material forms a contiguous thermo-structural base. Re-enforcement material comprising synthetic and/or non-synthetic components in the form of rods, rope, strapping, mesh, netting, geotextile fabrics or other dimensional forms laid longitudinally, or in a grid pattern, in single or multiple layers, tied or not tied all in situ sprayed with a high density closed cell, water resistant expanding two component polyurethane foam system. The reinforcing material may be nylon, polypropylene, fiberglass, other synthetic or non-synthetic materials or combinations of these materials.

L'invention concerne un matériau d'armature utilisable lorsque le nivellement définitif et/ou préliminaire est établi une fois l'excavation réalisée sur un site de construction. Il s'agit généralement d'un matériau synthétique, du type treillis ou tiges en nylon ou polypropylène, fibre de verre, ou autre matériau de renforcement spécifié, posé sur le sol. On établit une base renforcée en couvrant le matériau de résine polymère. En durcissant, la résine et le matériau forment une base thermo-structurelle contiguë. Le matériau comporte des éléments synthétiques et/ou non synthétiques sous forme de tiges, câbles, lattage, treillis, maillage, tissus géotextiles ou autres configurations dimensionnelles, pour une pose longitudinale ou en grille, à couches uniques ou multiples, avec ou sans attaches mutuelles, sous pulvérisation in situ de système de mousse de polyuréthanne expansible haute densité à deux composants, à cellules fermées, résistant à l'eau. Le matériau peut être en nylon, polypropylène, fibre de verre, ou autre produit synthétique ou non synthétique, y compris leurs combinaisons.
