Trenchless Underground Utility Repair & Inspection
A practical overview of no-dig methods for inspecting, cleaning, and rehabilitating sanitary sewer and stormwater infrastructure.
Aging buried infrastructure is one of the most pressing maintenance challenges facing municipalities, industrial facilities, and communities across the Southeast. Traditional dig-and-replace repair tears up roads, disrupts operations, and carries a steep price tag. Trenchless technology flips that model: instead of excavating from the surface, trained crews work from inside the pipe to inspect, clean, and rehabilitate underground utilities with little to no surface disruption. Provac specializes in these no-dig solutions, helping owners extend the life of critical sanitary sewer and stormwater systems while protecting the streets, landscapes, and operations above them.
What is trenchless pipeline repair?
Trenchless repair is any technique that restores an underground pipe without open-cut excavation. A camera first documents the pipe's condition; cleaning removes debris so defects are visible; then targeted methods — grouting, sectional or full-length liners, mechanical joint seals — repair the problem from within. Because the work happens inside the existing pipe, roadways, sidewalks, parking lots, and landscapes stay intact. The appropriate method depends on condition, access and design requirements. Compare anticipated disruption, cost and performance with replacement before selecting a repair.
Core inspection & rehabilitation methods
CCTV Pipe Inspection
High-resolution cameras traverse the interior of a pipeline to locate cracks, root intrusion, offsets, and sags. NASSCO-certified operators code every defect so owners receive an objective, repeatable condition assessment rather than a guess.
Hydro Excavation & Utility Locating
Pressurized water and vacuum equipment can expose selected utility points with a limited excavation footprint. Site conditions and utility requirements determine the method; excavation does not eliminate the risk of damage.
CIPP Pipelining
A resin-impregnated liner is inverted and cured in place, creating a seamless new pipe within the old one. Manhole-to-manhole CIPP rehabilitates large-diameter lines with decades of added service life and minimal surface disruption.
Pressure Grouting
Chemical grout is injected into joints and defects to halt infiltration and fill voids without excavation — a method to evaluate for infiltration control based on the defect and project specifications.
Pipe Cleaning & Vacuum Trucks
High-pressure jetting clears grease, roots, and debris while a vacuum removes it for off-site disposal, restoring flow capacity and preparing lines for accurate inspection.
Benefits of trenchless methods
- Minimal surface disruption — roads, driveways, and landscaping stay intact.
- Potential to reduce excavation and surface restoration, depending on the project.
- Work can be scoped around access and operating constraints.
- Proactive maintenance catches small defects before they fail.
- Targeted rehabilitation where the existing pipe and site are suitable.
