Cured in Place Pipe Houston. People living and working in the Houston areas have been contacting us regarding cured in place pipe (CIPP) lining technology. The Perma-Lateral system uses a PVC coated felt liner saturated with 100% solids epoxy. Using the 100% solids epoxy comes in quite handy for cured in place pipe lining in closed, confined spaces as it is odorless. Cured in place pipe lining benefits the Houston area as it will save property owners the time and money is would normally take to replace their Houston sewer and drain pipes.
