Trenchless Pipe Repair
Bringing Technology Underground
​
Pipes often fail or need repair due to the fact that pipes made of clay, orange burg, asbestos, wood, cast iron, and other materials are past life expectancy. This leaves the pipe prone to blockages, corrosion, deterioration, cracking, and collapsing.
​
Gremillion Mechanical’s Trenchless Pipe Lining Service allows us to repair most sewer or drain pipe with little or no excavating and without replacing the old pipe, as was traditionally the case. Instead, the old pipe is lined, creating a brand-new pipe within the old one.
​
Using the Cured In Place Pipe Process (CIPP), a resin-saturated felt tube made of polyester, fiberglass cloth, or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. Once the resin is installed it cures in the existing damaged pipe and assumes its shape.
​
Our methods and state-of-the-art equipment enable us to provide lower costs, a shorter time for repair, less inconvenience to business owners, and less chance of damage to other utilities and the surrounding environment than conventional dig and replace methods.

How It Works​
​
Gremillion Mechanical begins with installation prep where a 3-4 man crew cleans the pipeline, performs a video inspection of the pipeline, and transfers findings and measurements to Field Report. The installation continues as follows:
Pipeline is inspected with camera to find problem.
Pipeline must then be cleaned out to remove roots, dirt, debris and any potential objects that could disrupt lining.
Measurements of the pipelines diameter, depth and length are taken. The liner and calibration tube is then cut on site according to the measurements.
Resin is also measured and mixed according to the acquired measurements.
The resin is then poured into the liner and rolled or " wet out" many times to ensure complete impregnation of resin to liner.
Impregnated liner and calibration tube is then loaded into the inverter.
The liner is then inserted into the existing pipe using directional hoses and inversion heads. These ensure proper insertion.
Air pressure then inverts inside out allowing resin to bond with existing host pipe. The calibration tube acts as a balloon to keep the liner in place as it cures.
Once cured, the calibration tube is removed and the pipe is ready for service.
Past Projects
Sanitary Sewer Liner
​
A sanitary sewer line was repaired using our trenchless pipe repair services to prevent repeated clogging and backing up of sewer into an industrial building. A new clean-out was installed where the sewer line exits the building and a small section of limestone road was removed to provide access to the pipe. The existing line was cleaned, inspected via video camera, and prepped for installation of the liner. Using a Cured-In-Place-Pipe method, the pipe was lined with a PVC sleeve. The repair was completed in a substantially shorter time than traditional pipe repair and was minimally disruptive to the worksite.
