Trenchless Pipe Lining Overview
A cured-in-place pipe (CIPP) is a trenchless rehabilitation method used to repair existing main, lateral and vertical sewer pipelines. Maxliner USA offers the most comprehensive CIPP solutions for relining lateral and vertical pipelines, which allows plumbers and installers nationally to benefit from our deep expertise and innovations specific to the hurdles they face lining laterals that extend from the main to the home and vertical pipes or stacks typically found in commercial and apartment buildings. Such innovations include felt liners that curve, stretch and accommodate up to 90° bends as well as odorless, styrene-free epoxy to safely use under basements, garages and behind the walls of commercial buildings.
The process of CIPP involves inverting a felt or scrim-reinforced liner into a pre-existing pipe that is in need of repair. Epoxy thermosetting resin within the liner is then heated with hot water or steam which cures the liner in place. As the resin cures and hardens, it forms a tight-fitting, jointless and corrosion-resistant replacement pipe within the old pipe. Once fully cured, this cured in place pipe liner is now the new pipeline in service.
Step by Step
The first step of CIPP Sewer lining begins with the wet-out, or impregnation stage – which for lateral and vertical pipes is generally done on-site via a mobile wet-out system. During this stage, the pipe liner is impregnated with an epoxy based resin and mixed with a pre-determined hardener.
Next, the liner is inverted into the pipe with air or water pressure, placing the resin on the outside of the liner and fitting tight against the existing host pipe wall. The primary lining equipment needed to perform this process in lateral and vertical pipes includes a compact (to fit in tight spaces) inversion unit for lining, such as the Max LinerGun, a digital scale to accurately weigh the correct amount of resin and hardener and a calibration roller to evenly distribute the mixed resin through the liner.
After inversion, a calibration tube is inverted inside the liner which can then be cured via ambient, hot air, hot water, or steam. During this period, the hardener activates the resin causing it to harden and creating a fitted, smooth, and corrosion-resistant new pipe within the old pipe.
When necessary, a robotic cutting device, such as the Max Cutter ™ will be inserted into the newly cured in place sewer pipe liner to reinstate any branch line connections that may have been blocked by the new liner.
Advantages of CIPP for Laterals and Verticals
As a trenchless technology, CIPP effectively reduces infiltration and leaks in lateral pipes without digging up a yard, garage or basement. An important benefit of rehabilitating vertical pipes with CIPP, versus replacing the old pipe with a new one by excavation or other means, is the ability to repair the pipe without breaking up floors and tearing out walls. While this is important to homeowners, it is of critical importance to institutions such as restaurants, hospitals, prisons, universities, churches and any other facilities that cannot afford disruption to their operations, or displacement of people being served within their walls. It is also of great value to owners of historic buildings, as original and usually fragile flooring and walls remain untouched.
