This CFC- and halogen free product is designed specifically for use in drilled boreholes in underground mine and tunnel applications.
As an alternative to CARBOTHIX™, CARBOTHIX™ 2 is a pumpable grout helping water stopping.
It comprises of two components, component A, a special sodium silicate with additives and component B, a modified polyisocyanate.
After mixing the two components, the resin instantly achieves a grease-like viscosity level so that the mix stops flowing, even in large fissures, and requires pump pressure for displacement. The mix then hardens to form a hard resin.
The relatively low modulus of the resin, combined with high strength, provides a uniform transfer of local rock stresses over the whole length of the bolt rod.
