General Information WEBAC PU Injection Foam Resins PU injection foam resins (SPU) are designed for quickly and temporarily stopping water. They are characterized especially by their strong increase in volume and can also be used in case of highly pressing water, e.g. in dam building, tunnel construction, bridge building and special civil engi neering. The products are compatible with concrete, steel, foil, cable sheathing and WEBAC injection materials. WEBAC PU injection foam resins are resistant to salts, lyes and acids in concentrations usually found in buildings and structures. A...

General Information WEBAC PU Injection Foam Resins To ensure durable limited-flexibility filling and sealing of cracks, a secondary injection with WEBAC PU injection resins is necessary depending on the object. Immediately after the injection of WEBAC PU injection foam resins, the secondary injection can usually be carried out via the same drill-hole packers. However, if the secondary injection is carried out several hours later it may be necessary to install new drill-hole packers in different positions. • Observe the technical data sheets of the injection pumps and cleaners used • Refer...
