What is Trenchless Sewer Pipe Repair?
Trenchless sewer pipe repair involves fixing or replacing damaged sewer pipes without the need for extensive excavation. Traditional methods often required digging up large portions of the property, causing disruption, inconvenience and added expenses. Trenchless technology provides a less invasive solution that is both efficient and cost-effective.
How Trenchless Sewer Pipe Repair Works
Understanding the process behind trenchless sewer pipe repair helps illuminate its efficiency and advantages.
Pipe Lining (Cured-In-Place Pipe – CIPP):
The process begins with a thorough inspection of the sewer pipe using advanced cameras to identify the extent and location of damage, such as cracks, leaks, or corrosion.
Before the lining process, the sewer pipe is cleaned using high-pressure water or mechanical tools to remove debris, scale, and roots, ensuring a smooth surface for the new lining.
3.) Lining Installation
A flexible resin-coated tube, custom-sized to fit the damaged pipe, is inserted through existing access points, such as cleanouts or small excavations. The tube is then inflated and pressed against the interior of the pipe.
The resin is cured using hot water, steam, or UV light, creating a seamless and durable interior lining that adheres to the existing pipe. This lining effectively covers cracks, leaks, and minor structural issues.
1.) Access Points
The process begins by creating access points, typically at the beginning and end of the damaged pipe at specific intervals.
2.) Bursting Head Insertion
A bursting head, attached to a cable, is inserted into the old pipe. The bursting head breaks apart the existing pipe while simultaneously pulling in a new, high-density polyethylene (HDPE) or other suitable material pipe.
3.) Pipe Replacement
As the bursting head advances through the old pipe, it fractures and displaces the damaged sections, making way for the new pipe. The new pipe is pulled into place, ensuring a smooth, durable replacement.
4.) Connection and Testing
Once the new pipe is in place, connections are made, and the system is thoroughly tested to ensure its integrity and functionality.
