Pipe Rehabilitation: Pipe Bursting
In the past, replacing sewer laterals and/or trunk systems meant trenching through a considerable section of property. No matter how much care the plumbing contractor took to prepare owners/tenants, the sight of the disturbance and disruption of business created by the operation was tremendously upsetting to the owner. While the owner may understand the necessity of the new sewer service, he still found it difficult to accept the long period of disruption and the effects of open trenching.
Specialized Pipe Technologies’ pipe splitting process eliminates the majority of those concerns. Now SPT is able to promise minimal disruption and destruction. This clearly benefits the property owner and business operator. This kind of customer satisfaction has been hard to attain with open trenching.
Process & Equipment
An accurate and complete video inspection is performed 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 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 proven in these applications and continues to gain acceptance due to its many favorable qualities.
- Corrosion proof and virtually chemically inert International Association for Plumbing and Mechanical officials
- Long service life in excess of 100 years
- Heat fused “zero leak rate” joints

- Ground movement resistant
This SBCCI – Southern Building Code Congress International, IAPMO (International Association for Plumbing and Mechanical Officials), and UPC (Universal Plumbing Code) approved product has 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.
