CIPP Linings Explained: See What They Are & How They Work
CIPP linings are an alternative method to traditional pipe replacement. Known as one of today’s top repair methods for broken or cracked pipes, CIPP linings are a common go-to for sewer repair companies in Wisconsin and nationwide. But what are CIPP linings and what should you know as a homeowner or business owner about the repair method?
What Are CIPP Linings?
CIPP lining, also known as cure-in-place pipe linings, is a trenchless pipe rehabilitation process involving the insertion of a resin-saturated liner into a damaged pipe and curing it in place with hot water or steam. The result creates a new, seamless pipe within the existing one, extending its lifespan without the need for excavation. Since the damaged pipe does not need to be extracted, CIPP linings are generally cheaper and less invasive than traditional pipe replacement.
Types of CIPP Linings
|Inversion method||A procedure where a pipe liner is inserted and inverted with air pressure, forcing it to unroll and conform to the shape of the pipe. The liner is then cured in place with hot water or steam.|
|Pull-in place method||A process where a liner is pushed into the pipe with a winch or similar equipment and then inflated to force the liner against the pipe walls. Hot water or steam is used to cure the liner in place.|
|Fold-and-form method||A procedure where a liner is folded and inserted into a pipe before being expanded with air pressure to build a new pipe within the current one. Hot water or steam is used to cure the liner in place.|
Advantages of CIPP Linings
- Cost-effective: CIPP linings can be more cost-effective than traditional pipe replacement methods since there is less labor and equipment involved and excavation is not required.
- Non-invasive: There is no excavation or interruption to the surrounding region required with CIPP linings.
- Durable: CIPP linings provide a seamless, jointless pipe within an existing pipe to improve its overall strength and durability. This can lessen the chance of future damage and increase the pipe's lifespan.
- Versatile: CIPP linings are suitable for a variety of pipe diameters, shapes, and materials, including PVC, concrete, cast iron, and clay.
Applications of the CIPP Lining Process
|Sewer pipes||CIPP linings are appropriate for a wide range of pipe diameters, shapes, and materials.|
|Wastewater pipes||CIPP linings can improve flow capacity and reduce erosion in wastewater pipes requiring rehabilitation.|
|Stormwater pipes||CIPP linings can repair and rehabilitate stormwater pipelines and culverts by increasing flow capacity and lowering flood risk.|
|Water infrastructure||CIPP linings can increase water quality, eliminate leaks, and extend water infrastructure lifespan.|
How Trenchless CIPP Sewer Repair Works
Create access: Through minimally invasive access points, we can fix your entire piping system without disrupting the rest of your landscape or property.
Clean the pipes: Technicians clean the existing pipe system to get rid of build-up, obstructions, and scale.
Insert the liner: A custom-made liner coated in epoxy is pulled through the piping system. This liner somewhat resembles a sock, and the type used will depend on the purpose of the piping, whether for potable water, pressurized water, hot or cold water, and others.
Expand the bladder: Once the liner is in place for repair, the rubber bladder within the liner is inflated. As the bladder expands, it compresses and secures the liner with epoxy to the inside perimeter of the pipe.
Cure the epoxy: After the epoxy finishes curing, typically after 2-4 hours, the bladder is deflated and the equipment is pulled out of the piping. What is left is a new section of durable piping within the existing pipe.
What is a CIPP liner made of?
A CIPP liner is typically made of a flexible material, either felt or fiberglass, that is impregnated with resin. The resin is cured in place using hot water, steam, or UV light to create a seamless lining inside the existing pipe.
How long do CIPP liners last?
CIPP liners are designed to last between 50 to 100 years. The ultimate lifespan of CIPP liners depends on the type of resin used, the diameter of the pipe, the quality of the installation, and the operating conditions.
Can CIPP linings be used for all types of pipes?
CIPP linings can be commonly used for most types of pipes, including sewer, stormwater, wastewater, and potable water pipes.
