BEVEDOL S21 is a mixture of various polyols and additives which reacts with BEVEDAN 1F to form a tough/hard polyurethane resin foam.
BEVEDAN 1F is an isocyanate component on MDI basis. For solidification of largely loosened, dry or slightly moist strata zones.
This product is used in rock stabilisation, injection bolting and sealing against gas for cracks of more than 0.14 mm width.
The system consists of a resin (Bevedol®) and a catalyst (Bevedan®) which is delivered into the strata via a pump unit and injection gun.
The two components mix in the gun, which initiates the reaction of the product.
The low viscosity mixture penetrates the smallest fissures, hardens and ensures the consolidation and sealing of the area submitted to treatment.
