Trenchless pipe replacement saves your landscape

Pipe bursting, directional boring or pipe lining are trenchless methods for water and sewer line replacement on both residential and commercial properties.

Pipe Bursting

The pipe bursting method of trenchless technology involves pulling a new pipe through the damaged water or sewer pipe. The new pipe, which is made of polyethylene, is pulled through the damaged pipe using a high-powered pulling machine, while concurrently breaking the outer pipe. Pipe bursting normally requires access holes at both ends of the pipe to be replaced. The new polyethylene (PE) pipe is electro-fused in sections to become one continuous whole, seamless line. PE pipe is much smoother, more resistant to abrasion, and will not be damaged by microbiologically induced or chemical corrosion. The benefits to pipe bursting include fewer labor hours, undisrupted property, and easier clean up as well.

Directional Drilling

Pipe Lining

Cured- In- Place – Pipe Lining (CIPP) is a trenchless method of sewer repair. It requires little to no digging and significantly less time to complete than other sewer repair methods. It is suitable for repairing both short and long runs of pipe that do not need to be upsized.

CIPP involves inserting a flexible liner inside the existing pipe, inflating the liner, and exposing it to heat or ultraviolet light to dry and harden the liner inside the pipe. The liner essentially forms a smooth surface inside the existing pipe, restoring it to a near- new condition.

The work involves the following steps:

    • Remove roots from the pipe and flush debris from the pipe.
    • Set up a sewer bypass system, if necessary, to re-route wastewater to other nearby pipes during the pipe lining process.
    • Set up and run a Vactor truck, or sewer vacuum, to keep the pipe free of debris and water during pipe lining process.
    • Insert liner into the sewer pipe from the surface through a maintenance hole.
    • Expose the liner to heat or ultraviolet light to cure, or harden, the liner inside the pipe.
    • Open and reinstate sewer service lateral connections that were covered by the pipe lining.
    • Remove the bypass system, if any.
    • Conduct quality control inspections.
