Sanitary and storm lines under city streets and residential areas should be inspected to determine if voids exist.
The filling of these voids by internal pressure grouting will not only increase the load-bearing capacity of the structure but also will prevent infiltration and ex-filtration.
Pressure Grouting is the process of injecting a specified grout material under pressure to:
- Seal cracks in concrete and masonry structures
- Stabilize soil conditions under existing concrete slabs
- Fill voids behind retaining walls, below slabs and behind and under sewer structures.
- Eliminates infiltration and exfiltration of sewers, manholes, basins, holding tanks, ponds, etc.
