Sewer Pipe Relining with Epoxy


In this broadcast we are going to talk about relining sewer drains. Sewer pipe relining is the process of repairing damaged sewer pipes by creating a pipe within a pipe to restore function and flow. Epoxy relining materials mold to the inside of the existing pipe to create a smooth new inner wall. Relining sewer drains can be performed through a building's clean out access and often requires little digging. Sewer pipe relining is used to repair root damaged pipes, seal cracks and holes, fill in missing pipe and seal joint connections underground, and root drain pipes and storm lines and under concrete. The relined pipe is seamless and durable and all materials used in the relining process are nonhazardous.

For the millions of homes built for the burgeoning population of the 1950s and 60s, where sewer lines are reaching their expected lives, a cured in place pipe liner is an affordable and durable solution to smoothing the interior surface of deteriorating piping. The seamless application restores impermeability, eliminating leaks and future deterioration due to oxidation while improving the flow. Pinhole leaks burst at junctions and lead contamination from leaching pipe can all be effectively corrected within the pipe.

Nonhazardous epoxy materials injected through cleaned out drains and shut off valve terminations coat the pipe wall with a seamless durable material much like the lining of premium canned food containers. The process involves drying the pipes, sandblasting the inside walls with pressurized air, and a mineral that removes corrosion and oxidation and prepares the walls to accept the lining, then applying the epoxy lining. The process can be used on galvanized or black iron, steel, copper or plastic piping as well as coal tar impregnated cellulose fiber pipes that have not collapsed. Generally wherever it is possible to create a pipe within a pipe, epoxy relining can be employed.

The process is enhanced by using visual inspection systems and fiber optic lighting to inspect pipe before and during the process to gauge the degree of deterioration, diameter of the pipe, and effectiveness of the installation. And best of all, this process of sewer pipe relining is trench-less and requires very little excavation to your property, all but eliminating post-job cleanup, reseeding, etc. For more information on sewer pipe relining or any of the John C.
