1-component actively foaming hydrophilic and hydrophobic polyurethane resins are designed to instantly suppress and stop any leaks and water inflows, including under pressure.
Due to the high reaction rate and active volumetric expansion of 1K, polyurethane resins quickly fill the injection zone, creating a reliable barrier to incoming water.
Spetec resins are used as an independent product and do not need additional injection.
When using Tp-Injection PU resins, after stopping the water inflow, additional injection with 2-component polyurethane resin Tp-Injection PU 2100 or acrylic gels Tp-Injection AC 3100/3200 (depending on the project) is recommended.
