Epoxy pipe lining is a popular alternative to replacing old pipes. The epoxy coats the old sewer pipe, creating a new pipe with minimal digging and inconvenience. In theory, commercial epoxy liner repairs make sense. In practice, there are many things to keep in mind about the advantages and disadvantages. Here are some things to know.
How Are Commercial Epoxy Liner Repairs Made?
To apply commercial epoxy, a coatings contractor inspects the pipe with a CCTV to determine what is going on. Next, the pipe is cleaned out, so the pipe’s original diameter is restored, and the surface is clean for the epoxy to have something to adhere to. The liner is then applied to the pipe. A bladder is fed into the pipe with the epoxy. When the bladder is inflated, it pushes the epoxy up against the pipe. The bladder is left in the pipe for about 24 hours for the epoxy to cure, then removed. The contractor checks that everything works correctly.
