TYPE OF MATERIAL
 
SealBoss ® 1570 Water-Stop-Foam is a very flexible
hydrophobic water / hydro activated water cut-off grout and foam seal grout based on a MDI (methylene-diphenyl-isocyanate) polyurethane. The resin is 100% solvent free and 100% solids. The gel-time of the product is adjustable by the mandatory adding of a certain percentage of 15x Accelerator.
 
Upon contact with water 1570 Water-Stop-Foam reacts to a very flexible foam while expanding its volume 6 to 25 times. The cured material is flexible in its elongation and compression properties, and is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell.
 
Depending on the amount of accelerator added and the pressure of injection, 1570 Water-Stop-Foam reacts to a very dense, closed cell, flexible material or a more open cell, flexible product. For best waterproofing results the closed cell structure is desired.
1570 Water-Stop-Foam is extremely well suited to seal against water in moist and wet joints and cracks in concrete. The material offers high flexibility and elongation properties combined with good adhesion on wet and dry concrete surfaces in the injected environment. Higher injection pressures typically result in higher foam density and waterproofing quality.
 
To achieve most satisfying and permanent results in certain applications, a combination of 1570 Water-Stop-Foam with other systems of our product line may be advised. Ask your SealBoss technician for details.
