How long does a trenchless repair from NGI last?

NGI's cured-in-place pipe (CIPP) liners are engineered for a 50-year design life. The liner forms a structurally independent new pipe inside the existing host pipe, sealing cracks, root intrusions, and corrosion. NGI uses American-made United Felts liners manufactured to ASTM F1216 / F1743 standards in an ISO 9001-certified facility — a documented, traceable material specification.

How much can trenchless save versus digging?

Trenchless rehabilitation removes the single largest cost in traditional pipe repair — excavation and surface restoration. Because CIPP lining is installed from existing access points with no trenching, road demolition, or landscape restoration, the total cost typically runs 30–50% lower than open-cut replacement, while delivering the same 50-year design life. It also eliminates indirect costs like extended traffic control and road-closure disruption.

What is NGI's safety record?

NGI's Experience Modification Rate (EMR) — the insurance industry's measure of workplace safety — has stayed below the 1.0 baseline for three consecutive years, a track record municipal and commercial clients weigh heavily:

Verified by NCCI.

How does NGI document its work?

Every NGI engagement begins with CCTV pipeline inspection — pan/tilt/zoom camera systems that record the full inspection run. Pipe conditions are logged and coded to NASSCO protocol, and customers receive before-and-after video of the completed work. This documentation gives homeowners visible proof of the repair and gives municipal clients a defensible, compliance-grade record for capital planning.

Proven at municipal scale

NGI's results extend to permitted public infrastructure, which is inspected and signed off by municipal engineers:
