GeoTek HS is based on a polyol component (part A) and a polymeric MDI (part B). When mixed, a hydrophobic polyurethane foam is formed which is tough, rigid and resistant to a wide range of chemicals. Controlled expansion and high early strength allows this material to be used effectively for raising sunken slabs and pavements. GeoTek HS is also used widely for underpinning applications where increased soil bearing characteristics are required.
