Structural Repair
Pressure Injection Grouting
Fill cracks, voids and honeycombs under pressure to restore strength.
Overview
Injection grouting fills cracks, voids or honeycombs in concrete or masonry under pressure. It repairs cracks and strengthens damaged structural members, using quality chemicals and current technology to international standards.
Cracks in slabs, beams and walls let water travel deep into a structure. Surface coatings only hide them. Injection grouting pushes resin or cementitious grout into the crack itself, sealing it from the inside.
We fix packers along the crack line and inject low to high-viscosity grouts until the crack is fully filled, restoring both water-tightness and structural continuity.
- Seals the crack, not just the surface
- Deep
- Restores structural continuity
- Strong
- Minimal demolition
- Clean

Questions, answered.
Will you need to break my ceiling?+
No. We drill small holes, about 12 mm, along the crack. They are patched and painted afterwards.
