AkvaVIS S404 — polyurethane resin for consolidating soils and rocks

Other concrete repair materials

AkvaVIS S404 is a two-component polyurethane resin used to consolidate soils and rocks, seal off groundwater, strengthen foundations and carry out work using the “wall in soil” (diaphragm wall) technique. The material is produced in versions B, S and M with different reaction times: without water the reaction starts after 15 s, 90–150 s and 40 min respectively. The resin is injected with a pump through metal packers with mixing in a static mixer; it does not shrink, foams up to 1:10 and is suitable for cracks with an opening of more than 0.25 mm.
