Water & Wastewater

Proven and Cost Effective

The intent of chemical grouting in sewer systems is to seal leaks and stop infiltration and exfiltration. Most leaks in structurally sound sewer systems are through pipe joints, manholes, service connections, and the first few feet of service laterals. The most economical way to stop those leaks is with chemical grout.

The consequence of not taking action is far more costly than the cost of repair. Many municipal waste water plants treat twice the flow with groundwater infiltration at a much higher cost. Eventually, the collection system will become structurally incapable and a simple repair becomes a costly rehabilitation.


In addition to stopping infiltration and exfiltration within the sewer system, Avanti grouts also stabilize the soil outside and around the sewer pipes and manholes, which strengthens the soil and provides longer-lasting support. Avanti chemical grouts are effective in preventing erosion.
