This brochure is intended to document that chemical grouting is effective and long lasting. The case studies contained herein have been taken from numerous engineering and municipal publications.
The more we learn about our sewer systems, the more we discover how much customer service lines contribute to the expensive problem of groundwater infiltration.

Controlling inflow and infiltration is always an issue with wastewater collection systems. For the purpose of eating an elephant, we will concentrate on infiltration.
Chemical grout has been used successfully for more than 30 years to stop leaks in sewer systems. However, not all installations have been equally successful.
During a routine facility inspection at a major West Coast paper plant in Canada, a small leak appeared near the shoreline where an underground 42-inch fiberglass reinforced plastic pipe carried effluent to diffusers in the ocean.
The use of chemical grout, the original trenchless method, continues to grow, year after year. Both awareness and sales are up significantly over five years ago, industry statistics show.
