Tunnel umbrella injecton and screen injection in tunnel or gallery are made to waterproof and seal.
The rock or substrate to be secured is differentiated according to its pore volume, which determines the choice of the injection material. ARCAN OM resins stabilise and consolidate rock, gravel and coarse sand. For substrates with fine pores, BoRox AC and HydroBloc AC are the first choice because of their excellent penetration and stabilization properties. Cavities or caverns are filled with foam, mortar or resin, depending on their size, condition and location.
