Trenchless pipe bursting technology allows for homeowners and commercial property owners to repipe their aging or deteriorating plumbing and sewer drain line systems without tearing up their floors or yard landscaping. “Trenchless” means no trench is dug to put in new pipes, and SPT can often replace and entire pipe system with long term new pipe lining with nearly zero destruction to the property’s landscape.
Specialized Pipe Technologies’ pipe splitting process eliminates the majority of those concerns and SPT is able to promise mostly minimal disruption and destruction.
Trenchless Pipe Bursting Process & Equipment
A complete video camera inspection is performed first in order to determine the location and depth of all “wye” connections, tees, and access holes. The area between the entry and exit holes is completely undisturbed except for any laterals that would need to be reinstated for a complete system. A steel cable is pushed through the existing host pipe and is attached to the splitting head. At the other end of the cable is a hydraulic ram which makes the replacement of the new line possible without trenching the entire yard or floor. As the splitting head is drawn through the existing pipe, it fractures or cuts the old line. This allows the splitting head to bring in a new sewer line the same size or larger.
Our tools are designed to be used with High-Density Polyethylene Pipe (HDPE). This material is used worldwide for pressure, water, sewer, and natural gas utilities. HDPE has been shown to have multiple desirable qualities. It is corrosion proof and virtually chemically inert, has a service life of over 100 years, has heat fused “zero leak rate” joints, showcases a smooth interior high flow factor, has zero root intrusion, and is ground movement resistant.
HDPE is approved by the Southern Building Code Congress International, International Association for Plumbing and Mechanical Officials, and Universal Plumbing Code, having tested at triple the strength of cast iron. It is joined together with heat by a process called butt fusion, so that one continuous piece can be assembled for the splitting process.
After the trunk line is in place, SPT makes the necessary tie-ins with the appropriate fittings, clean outs, and transition couplings.
