Injection Systems

The right injection method for how and where a structure is failing.

The right injection method for how and where a structure is failing.

Injection systems treat problems beneath the surface — active leaks, cracked concrete, and unstable ground beneath a structure. We select the injection system based on the leak, the crack, or the ground condition being treated.

1. PU Injection Grouting
  • Used for active water leakage and sealing of cracks and joints.
  • Available as single-component and two-component PU resins, depending on the severity of the leak.
  • High-strength PU resins are used for heavier structural repairs, and slab lifting corrects settled concrete slabs.
  • Used for structural crack repair and concrete bonding.
  • A low-viscosity system that penetrates and seals fine cracks.
  • Structural, high-strength epoxy is used for heavier bonding and load-bearing repair work.
  • Used for fine cracks, water seepage, and difficult leakage paths.
  • Includes curtain injection, which creates a waterproof barrier behind the structure.
  • Block joints, expansion joints and multipurpose acrylic grouting handle additional sealing and joint treatment needs.
  • Used for filling cracks, voids, and cavities.
  • Cement-based and lime-based grouting, chosen based on the structural condition.
