Ronacrete Ronabond PU55 Polyurethane Foaming Injection Resin (Injection Grout)
Ronabond PU 55 is an MDI-based single-component polyurethane resin. On contact with water it reacts rapidly to form an elastic, closed-cell polyurethane foam seal, specially designed for rapid water stopping, plugging leaks and sealing cracks. Its pre-catalysed, low-viscosity nature allows effective filling of cracks and voids with a highly elastic seal.
