Sewer pipe lining is a process for repairing and replacing damaged, cracked, leaking, or backed-up sewer lines. In sewer lining, new epoxy-saturated pipe tubing is inserted into old pipes, inflated and cured into place using hot air, steam or blue light LED technology. This ‘no dig’ trenchless method eliminates the need to dig up trees, destroy sidewalks or excavate yards. As a result, damaged pipes are replaced with new seals that could survive for decades along the walls of existing pipes.
Let’s explore this pipeline system in detail.
How Does the Lining Process Work?
The Pipelining process starts with a comprehensive inspection of the existing pipes. Usually, a camera is used to identify cracks, leaks, or other problems that require addressing. After being inspected, the pipes are cleaned to remove any debris that can get in the way of the lining.
Next, the pipes are filled with a textile liner, a flexible tube covered with epoxy resin. After that, the liner is inflated and pressed against the old pipe’s walls, which helps the resin stick. The resin is hardened into a seamless, long-lasting pipe by adding hot steam or water during the curing step.
A cured-in-place pipe (CIPP), essentially a new pipe inside an old one, is the result of restoring functioning without requiring significant excavation. In addition to sealing existing pipes, this technique can increase flow efficiency and guard against future damage from ground movements or root incursion.
Understanding the Risk
Before delving into the benefits of pipelining, it is essential to understand the possible hazards linked to decaying drains and sewer pipes. Age, use, and environmental factors are some of the causes that can cause corrosion, cracks, and other types of damage to these pipes over time. These problems can result in leaks, sewage backups, and even structural damage to your property if they are not addressed.
Benefits of Sewer Pipe Lining
Cost-Effectiveness
Sewer pipe lining offers significant cost savings compared to conventional pipe repair or replacement techniques. While the lifetime of the liner reduces the need for regular maintenance or replacements, the removal of excavation lowers labour and material expenses.
Durability and Longevity
Sewer pipe linings are highly resilient to wear, corrosion, and root penetration. As a result, the rehabilitated pipes last longer and require fewer maintenance and replacement cycles.
Minimal Disruption
A sewer pipe lining system offers a significant advantage due to its non-invasive installation process. With no need for extensive excavation and disruptions to traffic, reducing disruptions has reduced downtime and inconvenience for businesses and residents.
Environmental Friendliness
Sewer pipe lining is an environmentally friendly alternative to conventional repair techniques since it reduces excavation and the resulting environmental effect. Plus, lining materials often come from recycled or sustainable sources, reducing the environmental impact.
Improved Flow and Performance
Sewer pipe linings’ smooth interior surfaces improve flow and protect against blockages and leaks. This lessens the possibility of backups and overflows and enhances the sewer system’s overall performance.
