WILLKAT® Foam

Two-component, high-foaming and fast-reacting silicate-based resin

 

description

WILLKAT® Foam is a two-component, fast-reacting, high foaming, silicate-based system with good substrate adhesion that provides a tough, mineral foam with simultaneous low shear strength that allows cavities to be stabilized and rock layers to be loosened while allowing excavation of the consolidated soil by mechanized methods (TBMs, drilling or milling equipment). The main field of application is tunnelling, which is mainly used for rapid backfilling of cavities in both civil engineering and mining. Thanks to its low Reaction temperature, WILLKAT® Foam is also suitable for use in coal mines. The discarded foam is easy to cut and therefore does not stick to the tunnelling machines, which means that it can also be used in TBM cutting wheels to stabilize and seal loose rock or friable soils.
