Trenchless Pipe Replacement Toronto & Ontario

Pipe Bursting, Directional Drilling & Horizontal Boring

Pipe Bursting
Pipe bursting is, just as its name suggests, a trenchless process that breaks apart the old pipe and replaces it with a seamless high-density polyethylene (HDPE) pipe. HDPE pipe is extremely strong but can be cut to size with carbide-tipped blades. It is exceptionally resistant to impact, abrasion, corrosion and root infiltration and will provide many years of trouble-free drainage.
 

Similar to sewer lining, pipe bursting can be used in large or small jobs. A sewer camera will again be used to determine what sections need replacement. To access the sewer line, two small holes are made at both ends of the pipe section. A cone-shaped bursting head is attached to a cable, pulled through the old sewer line and simultaneously breaks the old pipe while pulling in a new pipe. The end result is a high-quality pipe replacement without the expense or disruption of excavation.

Directional Drilling & Horizontal Boring

Directional drilling is a third option for trenchless pipe replacement that is both cost-effective and time-saving. A new sewer line can be installed with no existing pipe or re-directed to replace damaged or non-functioning pipe.
 

A pilot hole is prepared by inserting a horizontal boring head and hollow pipe into the ground at an angle. As the drilling area extends further underground, additional pipe sections are added to complete the pilot hole. At the end of the run, a reamer is attached and pulled back through the opening to expand it 25 percent larger than the pipe to be used. The new pipe is then pulled through the space created and connected at both ends. This innovative trenchless process saves significant time from previous methods and therefore, also saves on the cost.
