SealBoss 1500 Leak-Seal Foam is a hydrophobic, water-activated (hydro-active), water cut-off grout and leak-seal foam grout based on a phthalate free, MDI polyurethane. The product is 100% solvent free, 100% solids two component formulation to be mixed at a 1:1 ration by volume. Upon contact with water SealBoss 1500 Leak-Seal Foam reacts to a semi flexible foam while expanding its volume 30 to 40 times. The cured material 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 essentially does not shrink or swell. The advanced 1:1 formulation of the product results in a very dense, closed cell structure when injected under pressure. Very low counter pressure will result in a less rigid more expanded product. For best waterproofing results a closed cell structure is desired. Due to the low viscosity of the material, SealBoss 1500 Leak-Seal Foam offers good penetration in hairline crack injection. The product can be used for the filling of voids, cracks and honeycombing in stone or concrete structures. The moisture content of the soil must be sufficient to ensure reaction. To achieve most satisfying and permanent results in certain applications, a combination of SealBoss 1500 Leak-Seal Foam with other systems of our product line may be advised. Ask your SealBoss technician for details. The product is for professional use.
