Injection Grouting :

Injection grouting is a process to fill up cracks and hollow areas in the concrete.



Grouting Techniques
- Epoxy Injection Grouting: Cracks as narrow as 1 mm can be bonded by the injection of epoxy. The technique generally consists of establishing entry and venting ports at close intervals along the cracks, sealing the cracks on exposed surfaces and injecting the epoxy under pressure. This technique is successfully used in repair of cracks in buildings, bridges, dams and other types of concrete structures.
- Cement Grouting: Filling with Portland cement grout can repair Wide cracks, particularly in gravity dams and thick concrete walls. This is effective in stopping water leaks, but will not structurally bond-cracked sections.

Advantages
- Injection Grouting effectively fills capillaries and voids and does not shrink like cement slurries.
- Injection Grouting flows through the concrete easily and expands in voids and capillaries.
- Injection Grouting is very economical when compared with epoxy and polyurethane grouts.
- Seal Voids/Cracks in Concrete effectively
