Smart, Efficient, and Non-Invasive Pipe Rehabilitation

NG Companies delivers trenchless pipe repair solutions that restore damaged pipes without the disruption, cost, and environmental impact of traditional open-cut excavation.

Traditional pipe repair requires digging large trenches to access damaged sections, disrupting roads, landscapes, and daily operations. Trenchless pipe repair eliminates these problems by rehabilitating pipes from the inside, avoiding the need for extensive excavation. This approach saves time, reduces costs, and minimizes the environmental footprint of pipe rehabilitation projects.

Trenchless pipe repair is a method of rehabilitating damaged or deteriorating pipes by accessing them through small entry points rather than digging up the entire pipe run. Using advanced technologies like cured-in-place pipe (CIPP) lining and pipe bursting, our technicians repair cracks, seal leaks, and restore structural integrity from within the pipe itself. The result is a fully rehabilitated pipe system with minimal surface disruption.

With over 20 years of hands-on experience in subsurface utility solutions, NG Companies brings unmatched expertise to every trenchless pipe repair project. Our nationwide teams are equipped with the latest technology and trained in the most advanced rehabilitation techniques to deliver lasting results.

Faster Completion, Lower Costs

Trenchless methods dramatically reduce project timelines and eliminate the expense of excavation, backfill, surface restoration, and traffic management associated with traditional pipe replacement.

Durable, Long-Lasting Results

CIPP lining creates a seamless, jointless pipe-within-a-pipe that is resistant to corrosion, root intrusion, and infiltration, providing decades of reliable service after installation.

Safer & Environmentally Friendly

Minimal excavation means fewer safety hazards for workers and the public, less heavy equipment on site, and significantly reduced environmental disruption to surrounding areas.

CIPP Repair

Cured-in-place pipe lining installs a seamless, structural liner inside existing pipes that cures to form a new pipe within the old one, sealing cracks, joints, and leaks for long-term performance.

Manhole Rehabilitation

Restore deteriorating manholes with structural coatings and liners that stop infiltration, prevent corrosion, and extend the service life of these critical access points.

Injection Grouting

Seal leaking joints, cracks, and lateral connections by injecting specialized grout materials that expand and cure to create a permanent watertight seal.

Minimal Disruption

No need for large-scale excavation means roads stay open, landscapes remain intact, and businesses and residents experience minimal impact during the repair process.

Long-Lasting Solutions

Trenchless repairs typically last 50 years or more, providing a durable, permanent fix that eliminates the need for repeat interventions on the same pipe sections.

Cost-Effective

By eliminating excavation, surface restoration, and traffic management costs, trenchless methods deliver significant savings compared to traditional open-cut pipe replacement.

Frequently Asked Questions

How long does a trenchless pipe repair project take?

Most trenchless pipe repair projects are completed significantly faster than traditional methods. Depending on the scope and complexity, many jobs can be finished in a single day. Larger projects involving multiple pipe sections may take several days, but still represent a fraction of the time required for open-cut replacement.

What types of pipes can be repaired with trenchless methods?

Trenchless pipe repair works on a wide range of pipe materials including clay, cast iron, PVC, concrete, orangeburg, and corrugated metal. Our technicians assess each pipe's material, condition, and diameter to determine the most effective repair approach for the specific situation.

Will trenchless pipe repair damage my property?

No. One of the primary advantages of trenchless pipe repair is minimal surface disruption. The repair is performed through small access points, so roads, driveways, sidewalks, landscaping, and structures above the pipe remain undisturbed. This eliminates the costly restoration work required after traditional open-cut excavation.

How long do trenchless pipe repairs last?

Trenchless pipe repairs, particularly CIPP lining, are designed to last 50 years or more. The cured liner creates a seamless, corrosion-resistant pipe within the existing pipe that withstands root intrusion, ground movement, and chemical exposure for decades of reliable service.

How long does a residential trenchless repair take?

Most residential trenchless pipe repairs can be completed in 1-2 days, depending on the length of pipe and severity of damage. This is significantly faster than traditional excavation methods, which can take a week or more and require extensive landscape and hardscape restoration afterward.
