Stormwater systems experience surcharges throughout the year causing a vicious cycle of exfiltration and/or infiltration. As a result, supporting soils erode and voids in the sewer trench are responsible for pipeline failure. To fill voids, stabilize soil, and seal the system, chemical grout is the cost-effective solution.
For new construction, strict tolerances for pipe joints are challenging to maintain. To pass final inspection, chemical grout injected through the joint into the surrounding soil provides a long-term protective barrier against future erosion. For large man-entry systems, this can be performed with an expansive urethane resin. Small systems accessed by remote packer and CCTV equipment, acrylic grout injections create a lasting gel/soil matrix for a flexible seal.
