Inject Masonry Cracks & Leaks

Use crack injection when a structural or leaking crack must be filled through ports or gravity feed rather than only patched at the surface. ARDEX RA 142 supports structural crack repair in concrete and masonry. Mountain Grout Products support moisture-reactive sealing of leaking cracks and joints in concrete structures.

The Product evidence separates low-viscosity epoxy for structural crack bonding from polyurethane grout for leaking cracks or joints under moisture. ARDEX RA 142 is described for structural concrete and masonry cracks, while Mountain Grout evidence describes moisture-reactive barriers. Confirm whether the job requires structural bond, leak control, movement tolerance, or a combined system.

No. The local evidence snapshot for Mountain Grout Ultra is missing. Its live inclusion is supported by the manufacturer technical catalogue, which describes a low-viscosity hydrophobic polyurethane injection system for leaking cracks and joints in concrete structures. Refresh the local snapshot during catalogue maintenance and continue to verify the current manufacturer technical data.

The answer depends on the selected chemistry and Product instructions. ARDEX RA 142 evidence describes structural crack injection, while the Mountain Grout evidence describes moisture-reactive systems for leaking or wet cracks and joints. Inspect the crack, determine its moisture and movement condition, and follow the specified injection method rather than assuming one resin suits every crack.

Injection tools are included in the parent range as approved accessories, not as stage Products. The stage is defined by the injection resins with evidence-backed masonry or concrete use. The parent includes supported packers, hoses, guns, and measuring equipment. Confirm that each accessory fits the selected resin, port, pressure, pack size, and work method.
