CIPP (cured-in-place pipe) lining is a reliable, cost-effective way to repair water main and sewer lines. It’s a no-dig (trenchless) method of creating a thin-walled pipe within a pipe.
A flexible, collapsed tube (like an uninflated tire inner tube) is inserted into the damaged pipe. The tube is treated with a resin. The exact formula of the resin will vary depending on whether the damaged pipe is metal, cement, clay, or plastic.
Once the tube (lining) is inside the full length of pipe, compressed air is forced through the tube. This causes it to expand and press against the inner wall of the pipe. After the lining is in place, it’s left for a few hours to cure.
With CIPP, you avoid the cost and disruption of repiping. Yet, you gain the benefit extending the pipeline’s life expectancy by 50 years.
CIPP Water Main Lining
A great advantage of using CIPP pipe lining in water mains is that the interior of the pipe doesn’t need to be completely dry. The lining will adhere to the pipe and cure fully even when small amounts of moisture are present. This helps to keep time and dollar costs under control.
CIPP lining is the ideal method of repairing public water systems. Not only for the upfront cost savings compared to replacing pipes. The lining also helps preserve the quality of potable water.
CIPP Sewer Lining
There are additional health and safety considerations when repairing sewer pipe. To repipe by replacement is an unattractive option because of the time and equipment needed to do the work safely.
The CIPP method of lining deteriorated or damaged sewer pipes helps prevent future issues. However, few CIPP lining companies have the skills, experience, and equipment necessary to do the work.
CuraFlo has been rehabilitating sewer pipes using CIPP lining for decades. Our team of plumbing professionals receives comprehensive training. Along with learning how to use the necessary equipment, they are trained how to identify, avoid, and resolve health and safety issues.
Unlike indoor plumbing repair where epoxy pipe lining is used, trenchless sewer repair uses sewer liners. Sewer pipe liners are flexible tubes (like a bicycle tire inner tube) treated with a resin that adheres to pipe material.
Reputable sewer lining companies like CuraFlo, assess the sewer line cost per foot of pipe to be repaired. Generally, relining sewer pipe costs less per foot than replacement but each situation is unique.
CIPP Lining Cost
The cost of CIPP lining is usually calculated by linear foot of pipe to be repaired. Other factors that influence the cost are:
- Extent of damage
- Location of damage
- Amount of labor and equipment needed
- Permit fees
Reputable CIPP lining contractors, like CuraFlo, conduct detailed site visits before providing a detailed cost estimate.
When CuraFlo meets with prospective clients, we also explain what to expect and answer any questions about the CIPP lining process and product warranties.
