Sealboss 1510 Hydrophobic Water Stop Foam 5 Gal Pail
A hydrophobic water cut-off hydro / water activated injection foam grout and soil stabilization grout based on a MDI (methylene-diphenyl-isocyanate) polyurethane. The gel-time of the product is adjustable by the mandatory adding of a certain percentage of 15x accelerator. Upon contact with water it reacts to a seal foam while expanding its volume 30 to 40 times. The cured material is semi flexible and of a constant volume. The reacted material does not shrink or swell. Depending on the amount of accelerator added and the pressure of injection, it reacts to a very dense, closed cell, semi rigid material or a more open cell, semi flexible product. For best waterproofing results the closed cell structure is desired. It is is designed for cutting off gushing water of high pressure and speed. Due to the low viscosity of the material, it offers superior penetration in hairline crack injection. The product can be applied as a non-shrink, high strength soil stabilization grout when used with very little accelerator. The moisture content of the soil must be sufficient to ensure reaction. Recommended mix ratios are between 5% and 10% of accelerator added. In situations of high water flow rates and /or low temperatures, ratios may be increased to 20%. For soil stabilization applications ratios may be lowered to less than 5%. Water stop foam for infiltrating and gushing water:
- Defective concrete (cracked or honeycombed)
- Concrete joints and cracks
- Limestone and brick construction
- Waste water tanks and drinking water reservoirs
- Sewers, manholes, utility boxes, tunnels, dams, etc.
- Soil stabilization
