Description |
| Urethane GEL HF is a hydrophilic chemical grouting compound designed for use in sanitary sewer joint sealing, manhole water control, storm sewer sealing and soil consolidation. Urethane GEL HF is non-flammable VOC compliant liquid which mixed with water, forms an impermeable gel mass. It is environmentally safe and inert after curing. Urethane GEL HF is a multi ratio polyurethane, which will penetrate any water permeable soil. The cured material is a very effective water barrier. Two accelerators are available: one for the grout side Urethane GEL HFacc and one for the water side Urethane GEL HFaccW. Urethane GEL HF can be used in combination with reinforcing agent to enhance the strength of the gel mass.

| Influence of pH
|
The curing time increases with decreasing pH values. When highly alkaline (pH>10) or strongly acidic(pH<3) media, no gelification is formed.
