trenchless pipelining is

Plumbing magic

It may sound too good to be true but it isn’t! Once a plumber or contractor is certified by our team of trenchless experts they can skillfully and strategically place a new pipe within your old host pipe through a cleanout or other access point. This process is called trenchless pipelining .  All homes have a way of accessing the sewer system to allow your system to get flowing again without taking apart your home. If you think you may benefit from trenchless pipelining, contact us. We can book a pipe evaluation and potentially save you thousands of dollars on the repair.

We can help save your sewer and your property. If you are in need of sewer repair and want more information, contact us. We have a dedicated team of experts who will answer your call or email and get you on the right track to saving your sewer and restoring service.

lightray lrm system

The LightRay LRM system is your go to for mainline spot repair. The LRM works like a traditional spot repair system but with the added benefit of LightRay technology. The LRM uses the same large diameter LR3 packer, with a proprietary adapter, and is flexible enough to fit through a manhole into the mainline for repair lengths up to 9 feet. The LRM allows the operator complete control over the casting process with no stress over resin kicking off before positioning the packer is complete. The system does not create excess heat and can cast the liner in place in as little as 15 minutes depending on diameter.

LightRay takes away the anxiety of lining with its rapid deployment capabilities. No more carrying hazardous materials in your truck or trailer and no need to measure and mix on-site. LightRay liners arrive ready to install without any need for refrigeration. This dramatically reduces the variability from mixing resin and preparing liners in the field also eliminating the requirement for extra equipment. All LightRay technology uses flexible fiberglass liner coupled with a non-thermal UV casting resin that only activates when exposed to the specific light wavelength of the LightRay packer. LightRay doesn’t care about the temperature in the working environment or the presence of water, only providing you with a quick and consistent repair, every time.

Installing at the lateral termination

Structural and Watertight

Insignia™ O-Rings are available in a variety of diameters up to 8 inches and are installed as a standard part of LMK’s Performance Liner Lateral System, Sectional Spot Repair or T-Liner Connection systems. Once exposed to water, the O-Rings are capable of expanding 800% by volume creating the compression gasket that takes your CIPP rehabilitation to the next level of a watertight repair.

Did you know...

The Insignia™ product line is the patented gasket sealing technology compliant with ASTM F2561, F2599 and the rigorous F3240.

What are you doing to solve I & I?

Cities who are trying to reduce costs associated with excessive I&I are finding that rehabilitating manholes, lining city owned sewer pipes and rehabilitating residential laterals does not address the issue of I & I without the proper use of hydrophilic gaskets seals.

Trenchless Pipelining Saves Your Sewer line

These images of a pipe cutaway tell the story of what cured-in-place pipelining means. They illustrate a failing pipeline with root intrusion, corrosion, or even breakage. The lower pipe illustration shows the same pipeline with a rehabilitated relined and sealed new pipe liner. This is the core of our business and could mean the difference between costly excavation and rebuilding of infrastructure versus a simple day of ZERODIG™ pipe repair solutions.
