Once we have diagnosed the problem and removed any obstructions that would inhibit our ability to effectively repair the drain line, we can move forward with our trenchless sewer repair services. In this process, we use trenchless technology and equipment to restore the pipes from the inside, rather than removing them through excessive, intrusive digging. This is known as pipe or sewer lining.
Our technicians insert a flexible, inflatable tube coated with epoxy resin into the pipe. Its deflated size allows us to navigate the tube into the proper position with a metal liner that needs two access points on each end to be set in place. Once the tube is positioned where the damaged portion of the pipe is, we inflate the liner with compressed air. This forces the tube to conform to the inside of the host pipe, perfectly matching its diameter.
The pressure and expansion allows the liquidized epoxy resin formula to fill in cracks and leaks while evenly coating the inside of the pipe. Once this is done, the curing and hardening process can begin. Usually requiring several hours to completely cure, the curing is activated by the ambient temperatures in the pipe, although in some cases, the curing process can be quickened with steam or water depending on what is needed.
With the hardening process completed, this allows the felt liner to completely adhere to the inside of the pipe and act as the new pipeline. With added protection form the host pipe, the epoxy-based pipe liner that we install is a seamless and durable material that promotes efficient wastewater flow and resists corrosion and tree root invasions.
