Rock Mass Stabilization

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 PURseal is a fast-curing, permanently sealing PU injection resin. It cures into a compact, high-strength material without contact with water, while it reacts with a slight foaming action upon contact with water. The resin is used for subsoil stabilization and rock reinforcement, as well as for sealing against flowing and pressurized water in Foundation Pits, tunnels, and transportation infrastructure projects.

WEBAC PURseal M is a permanently sealing PU injection resin with German mining approval that is characterized by extremely rapid strength development. Without contact with water, it cures into a compact, high-strength material, while it reacts with slight foaming upon contact with water. The resin is used for anchor bonding as well as for Subsoil stabilization and rock reinforcement.

WEBAC PURseal M S is a fast-curing PU injection resin with DIBt approval for environmental compatibility when in contact with soil and groundwater. It cures into a compact, high-strength material without contact with water, while it reacts with a slight foaming effect when in contact with water. The resin is used for subsoil stabilization and rock reinforcement, as well as for securing foundation pits and tunnel structures.

WEBAC PURseal M SL10 is a PU injection resin with extended working and penetration times that has received DIBt approval for environmental compatibility when in contact with soil and groundwater. The resin cures into a compact, high-strength material without contact with water and reacts with a slight foaming effect when it comes into contact with water. It is used for subsoil stabilization and rock reinforcement, as well as for permanent waterproofing.

WEBAC PURseal M SL5 is a relatively fast-curing PU injection resin. It cures into a compact, high-strength material without contact with water, but reacts with slight foaming when it comes into contact with water. The resin is used for subsoil stabilization and rock reinforcement, as well as for securing foundation pits and tunnel structures.

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 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 SILcompact M thix is a non-foaming silicate injection resin with German Mining Approval. It offers excellent flow properties combined with rapid viscosity development and cures very quickly into a solid 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.
