Why Dig When You Can Go Trenchless for Sewer Line Replacement?

Trenchless technology for the replacement of underground pipe is not new, and the standard equipment and methods generally used are well known.

Pipebursting has been used successfully in both municipal and industrial applications to replace many different types of pipelines. Gas, water, sewer, and production lines, as well as communication ducts have all been replaced with Pipebursting, even in crowded underground situations. Experience has shown that the planned operation of pipebursting heads does not damage other buried utilities, even when they are only a few feet away. The surrounding soil serves to absorb the vibrations created by pneumatic heads, and pipe fragments are pushed far enough away to prevent damage to the new pipe. And, since most pipelines are below the frost line, Pipebursting operations can be carried out safely at any time of the year.

Since digging is limited to relatively small access pits, Pipebursting is much less traumatic than traditional pipeline replacement. Long sections of pipe can be replaced without introducing open trenches and heavy equipment. And, since the old pipe is left undisturbed underground, it does not present a disposal problem.

Trenchless Pipebursting Sewer Replacement

Why Trenchless?

No property damage-
Landscape, patios, driveways, sidewalks etc. remain intact

Minimal Restoration-
Only two holes required

Faster-
Line replacement at up to 3 feet per minute

Flexible-
Able to negotiate three 45 degree angles

Long Lasting-
HDPE pipe is far superior to PVC

Easy Transition-
Banded couplings

Neater-
Old sewer line stays in the ground

Cost Effective-
Reduced time

Residential Applications

Landscape, patios, driveways, sidewalks etc. remain intact. Little to no intrusion on customer.

Commercial Applications

Parking lots, public drives, building entrances & loading docks all can be remain accessible during a trenchless sewer line replacement.

High Density Polyethylene Pipe is inherently strong & flexible.

The pipe is corrosion proof with a long service life.

The smooth inner wall provides a high, quick flow rate.

Heat fused joints create a one-piece drain pipe.
