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-diphenylisocyanate)
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.
