Pipe Relining

Pipe Relining

People may be unaware of how intrusive and destructive things such as grease, roots, and rust can be on their plumbing lines. Pipe relining is minimally invasive and allows existing pipe to remain instead of tearing it out and doing a full replacement. This method may seem foreign but has been used on larger city sewer lines for over 40 years with great success. This process is done by inserting a felt tube that is saturated in resin into the existing pipe then inflating it and letting it harden in place. The result yields a brand new pipe within the already existing pipe and is said to have a life expectancy of 50 years (10 year warranty offered by BHI).

The process of lining a pipe begins by cleaning out the existing line. This is done by hydro jetting or pipe descaling depending on the condition. After the line is clean, a camera is sent into the line to verify that the pipe is a candidate for the relining. Following, a small hole (4 feet x 3 feet) is dug to expose the existing pipe. The liner is then treated with the resin and inserted into the old pipe. Once inserted, a tube is inflated which then expands the lining. After the lining has been expanded, the lining is cured and begins to harden. The tube is then deflated and removed and a camera is inserted again to inspect the results.
