CarboPur WFA is a fast reacting two-component-injection resin, CFC-free and halogen-free.
This resin is designed for sealing and consolidation in water-bearing strata.
CarboPur WFA, Component A is a mixture of various polyols and additives which reacts with the B-component to form a tough/hard polyurethane resin. CarboPur, Component B is a polyisocyanate.
The two components are pumped by a dual component pump at the volumetric ratio of 1 : 1, they are mixed thoroughly in a static mixer unit prior to injection into the strata via a packer installed in a previously drilled borehole.
