  • The trenchless reline is measured and the correct amount of resin is calculated
  • A rubber bladder is inserted inside the pipework
  • This is inserted inside the broken pipe and expanded to pipe size using an air compressor
  • The resin is then left inside to cure for 3 – 6 hours
  • The sock is removed and the pipe can be used straight away

The advantages of ‘no dig’ pipe repair

Repairing a pipe in Sydney Inner West under a concreted area, deck or landscaping by digging it up can take days or even up to a week. On average, relining can be done in a day as there is no need to dig anything up. The epoxy resin is also able to cure in a matter of hours. Sydney Inner West Pipe Relining. Pipes are able to be used as soon as the resin has cured. If a pipe is under your bathroom for instance, a dig up may require tiles and concrete to be jack hammered. Not only is this time consuming, it is also messy and disruptive to your lifestyle.

Relining is a permanent solution to ongoing pipe issues. Digging a pipe up and replacing it will allow tree roots back in through joints where the old pipe connects to the new one as a flexible joint needs to be used for the repair.

cured in place pipe (CIPP) is a no trench rehab method used to repair existing pipes. It is a jointless, seamless pipe lining within an existing pipe. As one of the most widely used rehabilitation methods, CIPP has applications in sewer, water, gas, and chemical pipelines ranging in diameter from 0.1 to 2.8 meters (2–110 inches).

The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair. Resin within the liner is then exposed to a curing element to make it attach to the inner walls of the pipe. Once fully cured, the lining now acts as a new pipeline. Sydney Inner West Pipe Relining.

A resin impregnated felt tube made of polyester, fiberglass cloth, or another resin-impregnable substance, is inserted or pulled through a damaged pipe. It is usually done from the upstream access point (manhole or excavation). It is possible to insert the liner upstream (e.g. from the downstream access point) but this carries greater risk. It is possible to install a liner from the downstream access point, upstream to a blind end; however, this carries the highest risk of all the CIPP installation methods. CIPP is considered a trenchless technology. Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional “dig and replace” pipe repair methods. The liner can be inserted using water or air pressure. Sydney Inner West Pipe Relining.The pressure required for insertion can be generated using pressure vessels, scaffolds or a “chip unit”. Hot water or steam can be used to accelerate the curing rate of the resin. If a fiberglass tube is used, the curing of the resin can be triggered though the use of UV light introduced into the tube. As the resin cures, it forms a tight-fitting, joint less and corrosion-resistant replacement pipe.

Service laterals are restored internally with robotically controlled cutting devices called cutters in the larger-diameter pipe. Smaller diameters (100 mm) can be opened remotely using smaller cutters designed for small diameter pipe. The service lateral connection can be sealed with specially designed CIPP materials, sometime referred to as a ‘top-hat’. The resin used is typically polyester for mainline lining and epoxy for lateral lines. Since all resins shrink (epoxy resins shrink far less than poly and vinyl ester versions) and it is impossible to bond to a sewer that has fats, oils, and grease an annular space exists between the new CIPP liner and the host pipe. Sydney Inner West Pipe Relining. The annular space exists in all installations just some are larger than others and depending on the severity may need additional rehabilitation. There are multiple ways to prevent water from tracking in the annular space and entering back into the waste stream including: water swelling material (hydrophilic), lining of the entire connection and host pipe with a continuous repair (YT repair) gaskets, and point repairs placed at the ends of the host pipe.
