Chemical Grouting

A Hard and Fast Rule Chemical grouting is used in sewer systems to seal leaks and to arrest infiltration. Most leaks present in structurally sound sewer systems are found in pipe joints, manholes, service connections, and within the first few feet of service laterals. The most economical means of repairing these types of leaks is with chemical grout. A two part gel is forced into cracks and openings. Prior to its application CWW can adjust the cure time from eight seconds to over an hour. The hardened product is continuous, irreversible, waterproof, and non-porous. Should roots be determined to be the compromising factor, an additive can be introduced to the gel to prevent any further root growth.

Multiple Properties In addition to preventing infiltration and exfiltration within a sewer system, CWW uses chemical grouting because it also serves to strengthen and stabilize the soil outside and around the sewer pipes and manholes. Chemical grouting is also effective to combat erosion and the encroachment of hazardous waste.
