Installing a pipe liner requires special equipment and is not a do-it-yourself project. During the procedure, the technicians place an epoxy-saturated liner into the pipe. They inflate a bladder inside the liner with air for two to four hours while the resin dries. Once the liner is dry, the technicians deflate the bladder and remove it, leaving a seamless, smooth lining in the existing pipe.
Prior to installing the pipe liner, the installers use a water jet cleaner to remove any sludge, roots or other foreign objects from the existing line. Options for inserting the liner include pulling it into place or using air to blow it into place. For sewer mains, technicians access the pipe through manholes. For residential mains, they dig a small hole at each end of the pipe. Inside the home, they make access through the basement, crawl space or walls.
The fiberglass and resin liner is odorless and tasteless once it dries. It is appropriate for use in sewer lines, potable water supplies and storm drains. It is appropriate for use in clay tile, cast iron and many other types of pipe. The cured liner is as strong as the original pipe and has a 50- to 100-year life expectancy. During the installation, it also fills the voids where the original pipe is missing.
