Bevedol® / Bevedan® is a two component, foaming polyurethane (PUR) injection system used to consolidate highly convergent strata. 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.
Licensed Product Application
We have over 40 years experience in the development, manufacture and supply of these type of products, as well as over 20 years of providing specialist contract application services. All our strata injection and cavity filling chemicals used in coal mines hold the German Authority permit (LOBA compliant), an internationally accepted standard for the safe and correct manufacture and application of these systems.

Geoflex® is a non-expanding, elasticised, two component injection resin system. Geoflex® Part A is a specialised sodium silicate with additives. Geoflex® Part B is a modified polyisocyanate.
The final product is a tough, flexible material with extremely high bond strength that is resistant against acids, alkalis, brines and many solvents. Ideal for grouting/injection coal and adjacent strata, sealing of injection anchors and stabilisation of debris.
