Quite a few methods can be used for no-dig repairs, but perhaps the most commonly used is trenchless pipe lining – also known as CIPP or cured-in-place pipe. This method is used to rehabilitate existing sewer and water mains without destroying large sections of landscaping or pavement, as would be necessary with traditional excavation techniques.
As the go-to plumber in Oro Valley, AZ, RAM Plumbing explains how trenchless pipe lining works:
Before beginning the trenchless repair process, a comprehensive video inspection of the sewage and drain lines is performed to check the condition of the existing pipe. This inspection allows for accurate diagnosis and pinpointing of any damages or obstructions that need to be repaired.
Once the initial inspection has been completed, we will move forward with cleaning the pipe. This process utilizes high-pressure water and sometimes chemical cleaners to clear out any obstruction or debris that could prevent the new pipe liner from being installed correctly.
The new liner is then installed after the pipe has been adequately cleaned. The liner is made of a strong yet flexible tube material, impregnated with an epoxy resin that adheres to the inside walls of the existing pipe. Once inserted, the resin is cured and hardened with heat or steam, creating a seamless new pipe within the old one.
Final Inspection and Testing
The curing process can take several hours, and once done, an inspection of the new pipe is conducted to ensure that it was installed correctly. After passing this inspection, we then test the newly repaired lines for any signs of leaks. If all tests are passed successfully, the repair process is officially completed.
How about when trenchless sewer replacement is the best option for your plumbing issue? The process is similar to trenchless pipe lining – the initial inspection and cleaning procedures are identical. The difference is that after the pipe has been cleaned, a bursting head is inserted into the existing line. The bursting head then breaks apart the old pipe while replacing it with a new PVC or HDPE pipe.
Trenchless pipe bursting can be used to replace up to 300 feet of pipe in a single pass. This process takes longer but often results in the best outcome for heavily damaged lines or large sections of missing pipe.
