What Does Trenchless Sewer Repair Entail?
Pipelining, or trenchless sewer repair, involves creating a new pipe within the existing deteriorated pipe to restore functioning.
Plumbers can complete pipe lining within a reasonable time due to minimal excavation, resulting in shorter downtime for homeowners. Here are more details on how pipelining works:
Assessment and Preparation
Before the relining process begins, plumbers thoroughly inspect the sewer line using tools such as video cameras. This inspection helps identify the extent and location of damage and obstacles that affect the relining process.
Plumbing professionals clean the sewer line using high-pressure water jetting to remove debris and roots. They can also use mechanical tools such as root cutters or descaling equipment to remove stubborn obstructions or mineral deposits.
Liner Installation
Plumbers saturate a flexible liner with a resin mixture made of materials such as fiberglass, polyester, or felt. They insert the liner into the damaged pipe through an access point such as a cleanout or manhole.
Using a combination of air pressure, water pressure, or mechanical means, plumbers pull or push the liner into place within the existing pipe. This process allows the liner to conform to the shape of the damaged pipe, creating a continuous, new pipe within the old one.
Inflation and Curing
After positioning the liner correctly within the existing pipe, plumbing companies inflate it using air or water pressure. This action causes the liner to expand and mold itself to the contours of the host pipe.
By conforming to the shape of the host pipe, the liner fills in gaps and cracks, providing a barrier against leaks and structural weaknesses. Plumbers cure the resin inside the liner using heat or UV light to create a hard surface, forming a new pipe within the old one.
Inspection and Reconnection
After the resin has cured properly, plumbing professionals inspect the relined section of the sewer pipe to confirm the structural integrity of the new pipe. They also trim excess liner material for a precise fit and smooth integration with the existing pipeline.
For effective sewer system functioning, plumbers reconnect sewer laterals or cleanouts. Once the relined section works correctly, these specialists open valves or gates they closed during the repair process.
When Is Trenchless Sewer Repair Used?
This process is effective for sealing cracks and leaks within the existing pipe. Trenchless sewer repair techniques are more environmentally friendly than traditional excavation methods.
By minimizing excavation and the associated disruption to the soil and vegetation, trenchless methods help preserve natural habitats and reduce the risk of soil erosion. The reduced need for excavation can result in savings on restoration costs, such as repairing landscaping features.
Trenchless methods are suitable for repairing sewer lines in challenging or hard-to-reach areas. Pipes located under driveways, buildings, sidewalks, landscaping features, or other structures pose significant challenges for traditional excavation methods.
Some structures, such as buildings or driveways, may not have sufficient clearance for excavation equipment to access the underground pipes. Cured-in-place pipe lining allows plumbers to perform repairs without the need to demolish or remove existing structures.
