Commercial Water Pipe Lining

Specialized Pipe Technologies can apply trenchless pipe repair processes to potable, or drinkable, water lines and water pipes that are 2” or larger in diameter in commercial properties. Our epoxy barrier coating method as well as investigation methods are all non-toxic and safe for consumption and everyday use.

Older water pipes and potable water lines are typically made out of either galvanized steel or copper. These pipes are always pressurized, and leaks are usually obvious due to the actively leaking liquid pouring from the pipe. Leaks and problems can occur under the flooring of a building or home, as well as outside of the building in the yard or landscaping area of the property.

SPT rehabilitates water lines with an epoxy barrier coating method that is proven to work extremely well with potable water lines. Our technicians will investigate the waterline or water main issue and discuss the quickest and most efficient solution with the property owners or managers.

Trenchless Water Pipe Plumbing

SPT excels at incorporating trenchless pipe lining technology into all of our work, which saves owners the hassle of digging up their flooring or landscaping to repipe the entire system. Trenchless pipe lining and rehabilitation allows our technicians to essentially renew the existing pipeline structure without digging anything up. Epoxy barrier coating technology utilizes trenchless principles and allows water pipes to be rehabilitated in a similar service.

Water Line Investigation

Traditional video inspections on water lines and water pipes is not the norm, but because we focus on 2” or larger pipes we can insert a camera if needed. Because potable water lines are constantly pressurized and leaks tend to be pinhole sized – they are often easily found due to active water leaking, pouring or shooting out of the pipe. An SPT technician will perform a full water line investigation of your property and piping system, with or without the aid of a video camera.

Rehabilitating and Lining Water Pipes With Epoxy Barrier Coating

Many drain pipes and unpressurized pipes will have the CIPP (cured-in-place pipe) lining method applied to them, but for pressurized and potable water lines, SPT will conduct epoxy barrier coating as the primary water pipe lining solution. Epoxy is blown directly into the pipe through a compressor, which can seal small leaks and prevent pipe corrosion, a feature that is particularly important with metallic materials.

Water Mains and Water Lines Pipe Repair

Whether you need repairs or rehabilitation on a large water main pipe, a water line 2” within the building, or a water line or pipe going to the public water main, SPT can perform trenchless water pipe repair on either type of job. We can do repairs on large diameter water main pipes as well as galvanized water and copper pipe ranging from 2 to 4 inches.

Trenchless Water Pipe Repair

SPT's water line repair uses an epoxy coating process, which is an economical and efficient alternative to traditional pipe system replacement. Our technology restores aged, corroded piping systems and copper pipes 2” and larger in diameter. Once the epoxy coating is applied to the interior of the pipe, it will seal and help protect the system from further deterioration. The process can be used on a variety of pipe materials, which include galvanized steel and copper.

How It Works

First, we drain the water out of the piping system and then run dry heated air through the pipes to ensure the removal of the moisture in the pipes. Next, we sand blast the pipes to remove all corrosion built up and create an anchor tooth for the epoxy to adhere to. Once the pipe is fully cleaned we then apply an epoxy coating system to the piping system until the pipe is fully coated creating a barrier internal pipe coating between the water and the pipe.

Expoxy Barrier Coatings

First, corrosion or a leak is identified which causes low water pressure or water damage in the walls, floors, or ceilings.

The pipes are dried with heated, compressed air to remove all moisture. The air also removes rust and corrosion build-up.


The cleaned pipe is reheated so that the epoxy coating will adhere to the internal pipe surface.

After epoxy coating has cured, a final leak test and inspection is performed. Water quality, volume, and flow are monitored and tested.
