Sewer pipe lining is a relatively new method of repairing sewer pipes without requiring excavation. It can save you money, time, and effort while reducing the property damage risk.
Traditional sewer pipe repair methods involve digging up and replacing pipes, which can be costly, inconvenient, and damaging to lawns, floors, and walls. Today’s technologies and techniques can solve various issues with minimal disruption to residents.
Trenchless Pipe Repair
Trenchless pipe repair is a widespread technique professional plumbers use to replace damaged sewer lines. This procedure eliminates the need for digging up your property and is usually completed in one day.
In this process, a unique liner is installed in the existing pipe. This liner is cured to form a new structural line within the old tube. It is designed to be incredibly strong and is rated for 50 years or more when installed correctly.
It can be applied to any sewer line, including cast iron, concrete, Orangeburg, or clay pipes. It’s also an eco-friendly option that reduces waste and helps save the environment.
Two main methods for trenchless pipe repair are directional drilling and pipe bursting. The former involves a horizontal drilling machine that bores into the ground for the entire length of the pipe that needs to be replaced.
Once the new pipe is inserted, it’s connected to the old line via a directional hose and inverted into place with pressurized air. The epoxy resin inside the liner is then cured and hardened by steam.
This method is ideal for repairing broken or damaged sewer lines in shallow areas. It can be done on residential and commercial properties and is a fast and cost-effective way to restore the functionality of your sewer lines.
Pipe Lining Contractors
Pipelining contractors in a sewer pipe lining company are experts at repairing sewer pipes using trenchless technology. They know how to line your pipes without tearing up your driveway or sidewalk and can help you save money on your plumbing bills.
They are also familiar with the latest methods in sewer relining, including cured-in-place pipe (CIPP) lining and shotcrete lining. Both restore underground pipes damaged by corrosion, roots, or other issues.
CIPP is one of the most effective and efficient ways to repair sewer pipes, offering long-term benefits. It prevents leaks and keeps the water inside your lines from mixing with corrosive chemicals.
A cured-in-place pipe liner can restore many types of pipes, including cast iron, concrete, clay, and PVC. The liner is a thin tube that contains a special epoxy resin that hardens after it is inserted into the pipe.
The CIPP process is fast and easy to use, allowing for a quicker and more efficient installation. It also results in a longer-lasting liner than other trenchless techniques.
Several municipalities worldwide struggle with aging and deteriorating sewer lines and wastewater systems. As a result, they need to find solutions that are safe, cost-effective, and long-lasting. This is boosting the growth of the global pipe relining market.
Pipe Lining Technology
One of the latest trends and innovations in the industry is pipe lining technology. It’s a long-lasting, cost-effective solution to fixing sewer and drains line problems.
It can repair and reline pipes up to a 2.8 meter (2-110 inch) diameter, including sewer, water, gas, and chemical lines. The process involves inserting a felt lining into a damaged pipe. The liner is then exposed to a resin to harden it.
The process is less disruptive than traditional “dig and replace” pipe repairs because it requires minimal excavation and only needs to be installed through existing access points. This eliminates the need to destroy property and disrupt local traffic, residents, and business operations.
Another trenchless rehabilitative method is a cured-in-place pipe (CIPP). It’s an epoxy-based lining system that adds 3 to 12 millimeters of interior wall thickness while remaining structurally sound.
CIPP also offers a 50-year design and service life, unlike the 15 to 40 years of traditional piping systems. It is environmentally friendly, resistant to corrosive chemicals and abrasives, and agnostic of the host pipe’s existing materials.
Cured-in-place pipe lining is a preferred trenchless method of rehabilitating wastewater and sewer main pipes. It has the potential to expand in North America and Europe due to growing concerns over aging infrastructure and rising demand for the restoration of pipeline systems.
Pipe Lining Materials
One of the latest trends and innovations in the industry is the development of high-performance, durable pipe lining materials. These materials can withstand the harsh environments of the job site and provide long-lasting results for system owners.
Cured-In-Place Pipe (CIPP) Linings
CIPP liners can be made from various materials, including fiber resin and fiberglass. These products can be used for repairing both gravity and pressure pipes.
As with all of the materials and equipment used in CIPP linings, manufacturers must adhere to stringent standards for safety and compliance. These requirements include using styrene-free resins and materials that will not contaminate the drinking water.
Another innovation in CIPP liners is using thermoplastic polyurethane (TPU) films for reinforcement in the liner. These films are rugged, flexible low-friction liners that resist the oils and chemicals found in wastewater.
In addition to CIPP felt liners, manufacturers are now offering several other innovative pipe lining products for relining lateral and vertical pipelines. These solutions address various challenges contractors face, relining laterals that extend from the main to the home and vertical lines typically found in commercial buildings.
CIPP has been a successful method for rehabilitating gravity sewer lines worldwide for decades. With the continued adoption of CIPP lining technology, manufacturers have evolved their product offerings with additional liners for relining laterals that require unique bends and transitions.
