Cured in place pipe is a soft liner that gives old sewer lines new life.
CIPP or cured in place pipe is a fiberglass resin in a felt liner that is blown in by air. CIPP gives new life to old pipe. It can fix holes in the pipe as long as the liner can get through the pipe. This is not possible if the pipe has collapsed. With CIPP you do less digging or no digging at all. You clean and clear the pipe of roots before installing the liner. Clean and clear pipe makes for a good surface for the liner and is standard practice for cured in place pipe.
How cured in place pipe works:
The most common CIPP liner is 3mm (although there are numerous other sizes, 6mm, 9mm and super flex for going around 90% turns) and it can be used for anything from 4″ pipe to 6″ pipe.
Cleaning the old pipe is a must and is the first step in CIPP. Next we run a sewer camera down the line to make sure it is clean and to get the right length for the liner. Then, we cut felt and mix fiberglass with hardener, pour fiberglass resin in to felt liner, and roll it though the liner. The resin is heat sensitive so care is needed — the hotter it is outside the faster the resin cures. Then it’s time for inversion. The liner is blown in by air with an inversion tank or a bladder gun. Next, a bladder is blown in and is inflated to hold the liner in place until it is cured. This is called an ambient cure. Hot water or steam can be used for a faster cure time.
CIPP has its place in the sewer repair business but it is not a fix all. Just as a knife, fork, and spoon have there purposed as utensils, so too does cured in place pipe have its place in sewer repair. It will not fix a collapsed pipe like Orangeburg pipe which softens over time. But it will fix most concrete pipe, clay pipe, and cast iron pipe. This is where a professional installer will help you decide what will work best for your sewer line repair.
