Waterproofing with hydro-expansive and water-reactive resins to block water infiltration in tunnels and underground rooms
Is injected through specific hand pumps or electric high-pressure injectors affixed by screw and permeates cracks up to widths of 0.2 mm.
In contact with water or moisture, increases after a few seconds, from 8 to 20 times its initial volume, through a process of reaction with the formation of a dense foam and elastic, which immediately stops the infiltration and hermetically seals the slot or cavity injected.
