Trenchless Pipe Lining in New City and Rockland County

New City Trenchless installs cured-in-place pipe (CIPP), an epoxy-saturated felt liner tube formed and hardened inside the failing host pipe, in the vitrified clay, cast iron and Orangeburg laterals that Rockland County’s postwar streets run on. One working day is typical from setup to the closing video. When the crew leaves, there is a continuous jointless pipe wall from the cleanout to the sewer main, and the lawn was never opened.

What the Liner Is and What It Becomes

The liner starts as a flexible felt tube, cut to the length and diameter the camera survey measured, then saturated with two-part epoxy resin under controlled vacuum so the wall is wet through with no dry spots. Dry spots matter: they cure into weak zones that can delaminate from the pipe wall years later, so wet-out is checked before anything goes downhole.

Once cured, the liner is a structural pipe in its own right under ASTM F1216, the standard governing cured-in-place rehabilitation. It does not depend on the old pipe for strength. Root entry points, offset joints and hairline fractures in the host are sealed behind a wall with no joints for roots to find again.

Which Rockland County Laterals Can Be Lined

Lining needs a host pipe that still holds its shape. That makes it the right call for most clay laterals with root-invaded joints, and for cast iron that has narrowed with scale buildup or channeled along the invert, once a hydro jetter and mechanical cutting have returned the wall to bare metal.

It is the wrong call for a collapsed pipe, or for Orangeburg squeezed too far out of round for a liner to press against. Those runs get pipe bursting instead. A bellied pipe sits in between: the liner follows the sag rather than correcting the fall, so a short belly gets lined with that understood, and a long one argues for bursting.

Length, diameter and the amount of cleaning the host needs decide where a job lands in the range. Open-cut replacement of the same line often runs 1.5 to 2x once excavation and landscape repair are counted.

Inversion or Pull-in-Place Installation

Inversion through an existing cleanout

The saturated liner is loaded into an inversion drum and turned inside out down the lateral under air pressure, which presses the resin face directly against the host wall. A calibration tube then inflates inside the liner and holds it round and tight against the pipe until the cure sets.

Pull-in-place between two access points

Where the run has access at both ends, say a two-way cleanout at the house and a downstream pit, the liner is winched into position flat and then inflated. Pull-in-place lining suits short sections and point repairs where inverting the full run would waste material.

Ambient, Steam and UV Cure

Ambient cure lets the resin harden at ground temperature: slowest, simplest, common on sectional work. Steam cure circulates hot vapor through the calibration tube and cuts the cure to hours, which is what makes same-day full-lateral work routine. UV-cured liners swap felt for a fiberglass liner sleeve hardened by a light train drawn through the pipe, the fastest and most controlled cure at a higher material cost. Diameter, length and resin system pick the method, not preference.

Diameter Loss and Branch Reinstatement

A cured liner costs the lateral a fraction of an inch of bore, and the trade is favorable: the epoxy wall is far smoother than corroded iron or stepped clay joints, so flow capacity in practice is preserved.

Where a branch joins the run at a wye fitting or a lateral tap connection, the liner covers the opening during the cure. A robotic reinstatement cutter then travels the new pipe and mills each connection open from inside, on camera, with no digging over the fitting. The liner ends are sealed so groundwater infiltration cannot track along the annular space between liner and host.
