A single-component, foamable polyurethane resin with an adjustable reaction time when mixed with a catalyst.
Applications:
• for rapid temporary sealing against pressurized water,
• sealing of special foundations: sheet pile walls (Larsen walls), palisade walls (drilled pile walls), slotted walls, and concrete placed underwater,
• reinforcement of loose (unconsolidated) subgrades,
• filling voids,
• stopping flowing water,
• stabilization of gravel layers.
Properties:
• single-component system with a catalyst,
• rapidly and vigorously expanding foaming resin upon contact with water,
• not too rigid foamed structure,
• adjustable reaction time (WEBAC PURstop ACC 1K catalyst),
• good reactivity and resistance even in the presence of alkaline water (pH up to 11).
