CURED-IN-PLACE-PIPE FAQS

As an alternative to trenching, we like to use cured-in-place pip (or CIPP). If you would like to learn more about CIPP, check out the FAQs below.

WHAT IS CURED-IN-PLACE-PIPE?
A resin-epoxy-saturated felt liner made of polyester, fiberglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation).
HOW LONG DOES THIS PRODUCT LAST?
Cured-in-Place-Pipe (CIPP), sometimes refereed to as "lining" or "sleeving" was first used in 1971 on a 36-inch sewer line at a mushroom farm in England. That relined pipe is still in operation today. The technology has only improved since the first CIPP installation. Sewer Renewal Specialists offers a 10-year transferable warranty but in reality, this new pipe will last as long as PVC, HDPE, or ABS.
DOES IT SHRINK THE SIZE OF MY SEWER LINE?
Many excavation companies that do not offer CIPP will use this as an excuse why someone shouldn't use this repair method. The short answer, yes, it is decreased by 3/16, of an inch. Though the size of your new line is smaller, a 4" sewer line that is concrete, cast-iron or clay has up to a 75% deceased flow rate of a CIPP sewer line. In reality, the CIPP can handle more flow and waste than older sewer lines.
IS IT LESS EXPENSIVE?
Generally, it is less expensive. Sometimes the CIPP method might be closer to the cost of traditional excavation, but there is not landscape restoration that is necessary, no asphalt to restore in the roadway, and no mismatched patches of concrete to worry about. When Sewer Renewal leaves a job after a CIPP installation, it's almost impossible to tell we were there.
