Cured-in-place pipe (CIPP) lining
Trenchless Sewer Pipe Repair in Alaska
Rehabilitate damaged sewer and drain pipes from the inside using a resin-saturated liner cured in place. When conditions qualify, we complete repairs without conventional excavation of your yard, driveway, floor slab or parking lot.
Warning signs
- Recurring sewer backups
- Root intrusion through joints
- Cracked or offset clay or cast-iron pipe
- Corroded or pitted interior walls
- Bellies, sags and separated joints
- Old orangeburg or transite laterals
How we diagnose the issue
- • Push-camera inspection to see actual pipe condition
- • Sonde locate to map depth and path of the line
- • Measurement of diameter, length and access points
- • Assessment of structural integrity for CIPP eligibility
How the service works
Step 1
Inspect and measure
Camera the pipe, locate access points and confirm the run is a lining candidate.
Step 2
Clean the host pipe
Hydro jet and cut out roots, scale and buildup so the liner bonds cleanly.
Step 3
Prepare and saturate the liner
Cut a liner to length and impregnate it with a two-part epoxy resin.
Step 4
Insert the liner
Invert or pull the liner through the host pipe using calibrated equipment.
Step 5
Cure in place
Cure the resin using ambient, hot water or steam depending on the system.
Step 6
Reinstate and verify
Reopen branch connections as needed and camera the finished pipe end-to-end.
When it's appropriate
- • Structurally sound host pipe with damage or joint failure
- • Residential laterals and many commercial mains
- • Runs with reasonable access at both ends
- • Diameters we're equipped to line
- • Pipe materials our system supports
When it isn't
- • Fully collapsed or severely offset pipe
- • Runs without required access
- • Pipes outside our supported diameters or lengths
- • Situations where excavation is genuinely a better long-term fix
Residential
- • Aging clay, cast-iron or orangeburg laterals
- • Root-intruded sewer lines
- • Sewer lines under mature landscaping or hardscape
- • Pre-sale rehabilitations
Commercial
- • Restaurant grease-line rehabilitation
- • Multifamily building mains
- • Retail and hospitality sewer laterals
- • Facility branch-line lining
Project example
50-year-old lateral relined in a single day, Wasilla
Homeowner had recurring backups from root intrusion into a clay lateral running under mature spruce. Camera inspection confirmed structurally sound pipe with failed joints. We jetted the line, installed a CIPP liner from the cleanout to the city tap and re-inspected. Yard intact. Trees intact. Line renewed.
