How Does Trenchless Sewer Replacement Work?
Pipe-bursting and Pipe Linings allow you to remove and change old or damaged pipes without digging trenches. Pipes and sewer lines that once required expensive and time consuming process can now be retrofitted with new pipe in less time, at a much lower cost, and with fewer downtime expenses.
Pipe bursting uses a high powered pneumatic system to break existing pipe into surrounding soil while replacing it with new pipe. The burst head technology cuts through clay tile, concrete, reinforced concrete and asbestos.
Advantages of Pipe Bursting
- Follows the existing path of the pipe
- Refit existing pipe through small entry hole
- Reduces potential damage to adjacent utilities
- Reduces excavation and restoration costs
- A preferred technology for upsizing existing pipes
The soft-liner is normally inserted into a pipeline from one existing manhole to another. As a result, no excavation is required, and the installation is fast and risk-free.
When the liner is inverted into place, it is expanded to press tightly against the interior of the host pipe. Once in place, the liner is heated to activate the thermosetting resins and causing the liner to cure into a new, structural pipe inside the original pipeline. The wall thickness and other design characteristics of a liner may be changed to meet your exact requirements.
During the installation process, resin from the liner felt is forced into cracks, joints, and other irregularities of the host pipe. This creates a mechanical lock between the host pipe and the liner and holds them both in place.
In addition to adding its strength to an existing pipeline, the liner also resists the corrosion and abrasion caused by effluents that destroy the host pipe.
The low coefficient of friction increases the flow capacity of the host pipe. In addition to its smooth surface, pipe lining also reduces turbulence by creating smooth transitions over offset joints, cracks, and missing wall sections.
