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.

Injection Products

MasterRoc MP 303CE

MasterRoc MP 303CE is a highly reactive two-component acrylic sealing resin with a low viscosity for good penetration. The product cures quickly, forming a highly flexible hydrogel with extraordinary swelling/re-swelling properties.

MasterRoc MP 307 CE

MasterRoc MP 307CE is a highly reactive two-component acrylic resin with a low viscosity for good penetration. The product cures quickly, forming a rubber-like resin with the ability to withstand certain ground and crack movement.

MasterRoc MP 309

MasterRoc MP 309 is a highly reactive two-component acrylic grouting resin with a low viscosity for good penetration. The product cures quickly, forming a hard, compact resin with high compressive strength for ground consolidation.

MasterRoc MP 320

MasterRoc MP 320 is a one-component injection system for the following applications, pre-injection grouting for underground application, post injection, ground improvement, water ingress reduction, slope stabilization.

MasterRoc MP 325

MasterRoc MP 325 is a solvent-free, low viscosity, hydrophilic grout for rock injection and consolidation of sand and silt strata

MasterRoc MP 350

MasterRoc MP 350 is a single component hydrophilic polyurethane based water sealing injection resin. It is specifically designed for the permanent crack sealing of concrete and rock in underground structures and the sealing of minor water ingress.

MasterRoc MP 355

MasterRoc MP 355 is a two-component, solvent-free polyurethane injection resin specifically designed for stopping rapid water flow and ground stabilization.

MasterRoc MP 355 1K

MasterRoc MP 355 1K is a one component polyurethane injection foam which only reacts when in contact with humidity or water. It prevents small to md-volume water ingress in underground structures and is also suitable for the filling of water bearing voids

MasterRoc MP 355 1K DW

MasterRoc MP 355 1K DW is a single component polyurethane injection foam which only reacts when in contact with humidity or water. It prevents small to mid-volume water ingress in underground structures

MasterRoc MP 355 MR0

MasterRoc MP 355 MR0 is a two component, solvent-free polyurethane injection resin formulated for ground consolidation with long injection lines. It is specifically designed for the stabilization of fractured rock, sands and gravels.

MasterRoc MP 355 Thix

MasterRoc MP 355 Thix is a two component, solvent-free polyurethane injection resin specifically designed to stop high volume water ingress and rapid water under difficult conditions (flowing water) in underground structures. It is suitable for cold water

MasterRoc MP 358 GS

MasterRoc MP 358 GS is a two-component solvent-free polyurethane injection resin formulated for the rapid stabilization of strata where high compressive and bonding strength is needed.

MasterRoc MP 358 SC

MasterRoc MP 358 SC is a two-component solvent-free polyurethane injection resin specifically formulated for rapid stabilization of strata where high compressive and bonding strength is needed.

MasterRoc MP 364 Flex

MasterRoc MP 364 Flex is a two-component, solvent-free polyurea-silicate injection resin specifically designed for rapid stabilization of strata and sealing against water.

MasterRoc MP 367 Foam

MasterRoc MP 367 Foam two-component, solvent-free urea-silicate foam is specifically designed for rapid cavity fillings, and for coal and rock strata consolidation.

MasterRoc MP 650

MasterRoc MP 650 microfine portland cement is designed for use in rock and soil injection. MasterRoc MP 650 has a small particle size making it particularly well suited for penetration into tight joints, fissures and pore spaces.

MasterRoc MP 800

MasterRoc MP 800 is well-graded cement milled from pure Portland cement clinker. It is specifically designed for pre-injection in all underground structures, post injection, water ingress reduction, ground stabilization and contact injection.
