By minimizing disruption to surrounding areas and reducing the need for costly and time-consuming excavation work, trenchless pipe lining has become a preferred choice for municipalities, utilities, and property owners seeking to address aging or damaged underground infrastructure. The Pipe Medic specializes in trenchless pipe repair in Roswell, GA. These are the steps we follow when we carry out a trenchless project.
Initial Assessment
The process begins with a thorough inspection of the pipes using CCTV cameras or sonar to assess the extent of damage and to confirm that trenchless sewer repair is indeed suitable.
Preparation
Before lining the pipes, any debris or obstructions are removed using high-pressure water jetting or mechanical cleaning equipment. This ensures that the lining material adheres properly to the inner surface of the pipe.
Lining Material Selection and Measuring
Depending on the specific requirements of the project and the condition of the pipes, a suitable lining material is chosen. Common materials used for trenchless pipe replacement include epoxy resin, polyester, or thermosetting plastic. The liner is measured and custom-cut to fit the length and diameter of the damaged pipe.
Lining Installation
The selected lining material, typically in the form of a flexible liner impregnated with resin, is prepared for installation. The prepared liner is inserted into the damaged pipe through existing access points, cleanouts, or manholes. Depending on the size and length of the pipe, this may involve using specialized equipment such as winches, air compressors, or hydraulic systems.
Once the liner is positioned within the pipe, it is inflated or inverted to ensure close contact with the inner surface of the existing pipe. Inflation can be achieved using air pressure or hydraulic force, while inversion involves turning the liner inside out as it is pulled through the pipe.
Throughout the trenchless sewer replacement process, technicians carefully monitor the position and alignment of the liner to ensure that it conforms accurately to the shape of the existing pipe. This may involve using CCTV cameras or laser-guided equipment to verify proper placement.
Curing Process
After the liner is correctly positioned, the curing process is initiated. This typically involves applying heat, steam, or ultraviolet light to activate the resin and facilitate its hardening. The curing time varies depending on the type of resin used and environmental conditions. Trenchless pipe lining technicians monitor the pressure inside the liner to ensure uniform distribution of the resin and prevent any leaks or defects.
Cooling and Final Inspection
The liner is allowed to cool and harden fully. A final inspection is conducted to verify the integrity of the newly lined pipe, including checking for any wrinkles, folds, or voids in the lining material. Any necessary adjustments or repairs are made to ensure the quality and longevity of the rehabilitated pipe.
