The Types of Trenchless Repair Methods

A broken sewer line can be a real nightmare, and the reality of the repair job can be even worse. For most homeowners, a damaged sewer line brings up visions of a messy yard with dug up trenches and large machineries. NGI Trenchless Pipe & Sewer Repair is the trusted pipe lining company offering reliable trenchless pipe lining in Roswell, GA.

This method of repair doesn’t require large trenches or machineries. Instead, we perform a camera inspection of your pipes before the repair. This allows us to visually inspect the pipe and assess exactly what the job will involve. After the repair is completed, we are able to view the targeted area with our camera and confirm that the repair has been done correctly and thoroughly. Here are the three types of trenchless sewer repair methods we use:

Slip Lining

Slip lining is a procedure most commonly used for non-residential applications. The process involves inserting a slightly-smaller pipe into the existing pipe and then filling the gap with grout. The size of the pipe is made smaller, so this process is not recommended for pipes that are initially smaller in diameter. Sewer pipe lining in Roswell, GA is cost-effective, faster than conventional pipe-repair methods, and has a life expectancy of 50 to 100 years.

Cured-in-place (CIPP) lining

Cured-in-place lining is a process that involves running a felt or fiberglass liner filled with epoxy into the existing pipe and then inflating it. After being allowed to cure for approximately 24 hours, the liner is removed. The result is a pipe that is as good as new with no leaks and all damage repaired. CIPP pipe lining in Roswell, GA is quite inexpensive, requires no holes or access points, and can last up to 50 years.

Spray Lining

Spray lining or brush lining is similar to CIPP, but does not involve the introduction of the liner. Instead, resin or epoxy is sprayed along the inside of the pipe and allowed to cure. This seals cracks and small holes, eliminating leaks. The process is one of the oldest used, but it is a superior method for cast iron pipe lining in Roswell, GA, as it stops the ongoing corrosion inherent in pipes made of this material. It is also excellent for sealing pipe joints that may be leaking sewer gases. Spray lining or brush lining can be used in pipes as small as 1.5 inches in diameter and has a materials warranty of 15 years
