Supershield INJECT 2000

SUPERSHIELD INJECT 2000 is a hydro-expansive polyurethane resin that is solvent-free and is ideal for sealing both small and large water leaks in concrete or solid masonry through injection. It is also perfect for filling and sealing small cavities, joints, and discontinuities that are subject to movement. In contact with water, SUPERSHIELD INJECT 2000 forms a flexible polyurethane foam. Technically, it is a one-component product which reacts spontaneously with the water present in the masonry to be sealed. The speed of reaction with just water, however, would be very slow relative to the construction site requirements. It is therefore essential to use an expansion accelerator, sold in combination with the same resin (component B). The polyurethane foam resulting from injection operations, will keep its volume stable once expanded. A good resistance to hydraulic pressure in the water flow after about 1-2 minutes from the time the reaction took place. The formation of CO₂, typical of the polyurethane reaction, will further pressurize the system, thus favoring the penetration of the resin in the cracks and cavities. In a free environment, SUPERSHIELD INJECT 2000 expands to about 20 times its initial volume.
