Instead of extensive excavation, this method involves inserting a flexible epoxy resin liner into the existing pipe to create a new seamless inner surface. Once cured, the liner provides structural integrity and effectively prevents further degradation. Due to its numerous advantages over conventional methods, pipe lining has gained significant popularity.

Knife River Sewer Line Hydro-Jetting

Sewer Line Hydro-Jetting

Sewer line hydro-jetting is a powerful cleaning method used to clear clogs and remove debris from sewer lines.
