Injection Systems for Ground Consolidation

Avoid the unexpected with Master Roc injection technologies

MasterRoc offers a complete range of injection products and technical support in ground consolidation.

Microcements (MasterRoc MP 650) and mineral grouts (MasterRoc MP 320 and MasterRoc MP 325) known as colloidal silica, represent a significant technological advantage in injection. These systems allow a cost effective approach and improve working safety with minimal environmental consequences. Due to their fineness, they provide extremely effective penetration into fine cracks in rock and finely-grained soils to give efficient water tightness, stability and durability.

Foaming, water sensitive polyurethanes (MasterRoc MP 350 series) are ideally suited to combat water ingress quickly and effectively. For particularly difficult cases the solution is a combination of drainage and the injection of a rapid reacting foaming resin.

Quick reacting and non-water sensitive polyurea silicate systems (​​MasterRoc 360 series) quickly stabilize poor ground. The expanding foaming system is excellent for void filling.

Our range of acrylic resins (MasterRoc MP 303 and MP 307) is particularly suitable for rehabilitation injections for precast concrete segment linings and brick and masonry-lined tunnels.
