What We Do
LightRay Systems We Deploy
Different pipe sizes and conditions call for different systems. We deploy the right LightRay unit for your specific situation.
LightRay LR3 — Spot Repairs (3"–12")
The LR3 is our workhorse for residential and commercial spot repairs on 3- to 12-inch pipes, including 45° and 90° bends. Pull-in-place or push-in-place installation. Cure times as low as 10 minutes. Ideal for localized cracks, root intrusions, and joint failures without opening walls or pavement. LR3 product details →
LightRay 2-Inch — Laterals & Branch Lines
Built for 2-inch residential drain lines, P-traps, and tight lateral branches where traditional lining equipment can't reach. Flexible packer navigates bends and P-traps with ease. Cures in under 10 minutes once positioned. Perfect for bathroom drain lines, kitchen branches, and tight-access interior plumbing. 2-inch system details →
LightRay LRI — Lateral Inversion Lining
The LRI uses inversion technology to line lateral pipes from 3"–8" — casting up to 150 feet of pipe at 6.3 feet per minute. The cold LED light train navigates up to 90° bends internally, making it ideal for long lateral runs, sewer laterals from house to street, and multi-bend configurations. LRI system details →
LightRay LRM — Mainline Sewer (8"–12")
The LRM handles large-diameter mainline sewer rehabilitation — repairing sections up to 9 feet per liner with a 500-foot reach between access points. Fits through standard manholes. Cures in approximately 15 minutes. The right tool for municipal laterals, commercial mainlines, and large-diameter infrastructure. LRM system details →
Pre-Lining Camera Inspection
Every LightRay job starts with a video camera inspection to map the damage, confirm pipe diameter, and verify the pipe can accept a liner. We won't propose lining if the pipe needs a different solution — you get an honest assessment, not a sales pitch.
Pre-Lining Pipe Cleaning
The pipe interior must be clean for the liner to bond properly. We hydro jet or mechanically clean the line before lining to remove root material, scale, grease, and debris — ensuring a full-contact seal and maximum liner lifespan.
How LightRay UV Lining Works
Camera Inspection
We run a video camera through the pipe to pinpoint damage, measure diameter, and confirm the pipe is a candidate for lining.
Pipe Cleaning
Hydro jetting or mechanical cleaning removes roots, scale, and debris so the liner makes full contact with the pipe wall.
Liner Insertion
A pre-impregnated fiberglass liner — saturated with non-VOC UV-activated resin — is positioned precisely over the damaged section.
UV Cure
The LightRay LED packer activates the resin with UV light. The liner cures hard in 10–15 minutes, creating a seamless structural pipe within a pipe.
Why UV Curing is Better Than Heat Curing
Traditional Steam/Heat CIPP
- Cure times of 4–8+ hours
- Temperature-dependent — humidity and heat affect results
- Requires bulky boiler equipment on-site
- Higher VOC resin fumes
- Service disruption for most of the day
LightRay UV CIPP
- Cure times of 10–15 minutes
- Weather- and temperature-independent
- Compact equipment — works in tight spaces
- Non-VOC resin — safer for enclosed spaces
- Service restored within the hour
