MULTIGEL is a solvent-free, non-toxic, single-component water-reactive polyurethane injection resin. It reacts with water to form a flexible hydrophilic barrier. Depending on the amount of water in the mixture, when cured, MULTI-GEL will vary in consistency from strong elastic rubber-like foams, to stable gels containing as much as 800% water. After curing, MULTI-GEL absorbs limited amounts of water and will shrink slowly if allowed to dry.
- In the range of 2:1 to 8:1 water:resin ratios, hydrophilic gels are obtained in less than one minute
- Non-flammable and contains no volatile solvents
- High penetration rates through soils and grouted soils can be excavated
