Filling of Voids and Cavities

WEBAC HIS is a hybrid injection resin used as a reactive component for large-volume cement grouting and holds National Technical Approval. It is characterized by rapid strength development and cures even underwater to form a stabilizing and sealing material. The resin is used to secure Foundation Pits and tunnel structures, as well as for subsoil stabilization and void filling.

WEBAC PURstop 1C is a single-component, polyurethane-based injection resin with a catalyst. Upon contact with water, it reacts rapidly and expands vigorously, forming an elastic, adaptable foam that reliably stops water ingress. The reaction time can be adjusted using the WEBAC PURstop ACC 1C catalyst. It is suitable for sealing Foundation Pits, for solidification of loose soils, and for filling voids.

WEBAC ram injection lances are modular lances designed for injecting resins and acrylic gels. They are easy to use and are employed for soil and foundation stabilization as well as for filling voids.

WEBAC SILcompact M is a non-foaming silicate injection resin with German Mining Approval. It offers excellent flow properties and cures very quickly into a compact material that can be cut and planed. The resin is used for stabilizing and sealing tunnel structures and in mining applications.

WEBAC SILfill is a low-viscosity silicate injection foam resin. Even without contact with water, it forms a fine-celled foam with a high expansion ratio and cures quickly into a material that can be cut and planed. The resin is used for shield injection in the immediate vicinity of TBMs, as well as for subsoil stabilization and rock reinforcement.

WEBAC SILform is a silicate injection foam resin that foams and sets rapidly. It reacts with or without contact with water and cures into a pressure-resistant material that can be cut and planed. The resin is used for stabilizing and permanently sealing tunnel structures and in mining applications.
