Introduction
Grouting involves injecting a fluid material to fill voids, cracks, or cavities in concrete, masonry, or soil — restoring strength, stiffness, or watertightness.
Type | Description | Application |
Cementitious Non-Shrink Grout | High flow, shrinkage-compensated cementitious grout | Baseplates, column bases |
Epoxy Grout | Precision grouting for heavy machinery | Machine foundations |
PU Injection Grout (Hydrophilic / Hydrophobic) | Expanding polyurethane resin for sealing leaks | Basements, tunnels, retaining walls |
Acrylic / Vinyl Injection Grout | Ultra-low viscosity resin for hairline cracks | Damp areas, roofs, retaining walls |
Relevant Codes
- EN 445 / EN 447 — Grout flow & strength
- ASTM C1107 — Non-shrink grout
- EN 1504-5 — Concrete injection
- IS 14311 — Grouting for repair & rehabilitation
Consultant Guidance
- Use epoxy grout for precision baseplates or high load areas.
- Use cementitious grout for large volume base or gap filling.
- PU grout for active water leaks (hydrophilic for wet, hydrophobic for dry).
- Control injection pressure and curing as per EN 1504-10.
