Manholes

Ease of access and visibility make manholes the "low hanging fruit" of sewer system rehabilitation. Every manhole is unique with its own set of problems based on age, construction materials, and confluence of pipe penetrations. Condition assessment drives remedial action ranging from point repair to curtain grouting the entire structure.

From the invert to chimney, multiple technologies exist to solve undesirable water intrusion and most require a clean, dry, infiltration-free environment. The first step is to stop active water leaks. Chemical grout is your best defense and complimentary solution to lining, coating, and other structural repair alternatives.
