Ultraviolet Inversion Is Here!

LightRay’s state-of-the-art Cast-in-Place-Pipe technology ushers the Trenchless industry into the twenty-first century, offering new opportunities for plumbers and municipal contractors by significantly reducing time and resources, lowering risks and costs with much faster and higher quality results compared to the older traditional thermal heat or ambient curing processes.

LR3: Lateral Spot Repair

The new LightRay LR3 LED UV system is the most advanced cast-in-place UV pipe technology allowing the operator complete control of the curing process. Our patent-pending, state-of-the-art technology can significantly reduce your costs and risks when compared to traditional thermo-setting or ambient-cured CIPP liners, creating new opportunities for plumbers and municipal contractors.


Features of LR3

  • Repairs pipe diameters of 3-, 4- or 6-inches including transitions
  • The 100-foot hose couples with 5-, 10- or 20-foot packers to perform repairs
  • Casting times of 10 minutes or less
  • Liner materials arrive ready to install with no wet-out needed
  • Easily navigates 45 and 90⁰ bends
  • Training included and 24/7 support
  • Designed, built, and supported in the USA


Perfect Cure in minutes

The LR3 is both a pull-in-place and spot repair system giving you the flexibility to perform both operations by only changing the proprietary double-strand cold LED repair packer. The LightRay non-VOC resin is pre-impregnated into the high-performance fiberglass liner and shipped ready to install for no-dig small-diameter pipe infrastructure repairs. Once the install site is prepped, casting times in under 10 minutes can be achieved eliminating the risk of premature or prolonged curing times due to temperature variations.


Packer + Liner + Resin

The patent pending LightRay packers are a proprietary cold LED double-strand system offered in standard lengths of 5, 10, and 20 feet. Offered in diameters of 3, 4, and 6 inches, these UV packers require only 24 volts to cure and are protected and reinforced by a specialized silicone bladder for multiple uses and sustained durability.

The leading-edge navigation spring assists in going around bends and can house a radiofrequency device for location and tracking below ground or within walls and floors. In addition, the spring is removable allowing the hook to be exposed for all pull-in-place applications.

  • Available in 3-, 4- and 6-inch diameters
  • Double-strand, cold LED lights for industry-leading cure times
  • Reinforced, multiple-sized silicone bladders
  • The leading edge removable spring guide exposes the pull hook
  • Specialized retrieval harness
  • Quick disconnect system for easy packer switching

ready to install


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 greatly reduces the variability from mixing and preparing liners but also eliminates the requirement for extra equipment in the field allowing for rapid deployment of the system.

The LightRay LR3 system incorporates non-thermal UV casting resins along with high-strength flexible fiberglass pipe liners. No matter what the current temperature is above or below ground, the casting times are consistent anytime and every time, all in under 10 minutes.

  • Resin-impregnated liners in 3-, 4- and 6-inch diameters including transitional flex
  • Cures in as little as 5-10 minutes
  • No refrigeration is necessary and 6-month shelf life when stored in a controlled environment between 50-70 degrees
  • Standard UV resins are non-VOC (no odor)
  • Exceeds the structural requirements of ASTM F1216
  • Sold in rolls of 50, 100, and 300 feet
