Localised Repair Systems are used to address point service problems or individual structural defects within a pipeline as opposed to full manhole-manhole rehabilitation. In some instances, it is not necessary to reline the entire pipeline. A sectional point repair or sleeve liner can be installed to repair defects such as sealing redundant lateral connections, cracked pipes, root intrusion, infiltration exfiltration or mechanical damage and erosion.
CIPP PATCH REPAIR
Cured in Place Pipe (CIPP) patch repairs are a cost-effective way to repair isolated defects within a pipeline. The patch is a short sleeve of glass-fibre reinforced matting impregnated with silicate resin. The repair is attached to a packer which is pulled through the pipe and inflated over the defect. The patch is cured in place and bonds to the existing pipework, restoring the original pipe's structural stability.
The CIPP sectional point repair can be used for the renovation pipelines with circular cross-sections of concrete, reinforced concrete, stoneware, fibrous cement, cast iron, GFP, PVC-U and cast-iron materials. The procedure can be used irrespective of the stated raw material of the laid pipe for the renovation of crack formations (e. g., radial cracks and longitudinal cracks and combinations of longitudinal and radial cracks), mechanical wear, corrosion and closure of side branches and leaking pipe connections.
Suitable for repairing pipes with a diameter of 100mm to 800mm and a rehabilitation length of 1000 mm to 5000mm. The renovation length for each point repair lies between 500mm and 5.0 m, depending on the packer used and the material. More extended areas of damaged pipe can also be renovated by an overlapping technique.
No volatile organic compounds (VOC) or styrene is released, making the system odourless and environmentally friendly
High chemical and heat resistance
Ambient-cure resins with a short cure time of approx. 1 to 3 hours
Virtually no shrinkage ensures a good frictional bond with the host pipe
Cures in the presence of water. Seals infiltration
The tested service life of min. 50 years (10,000 hrs) according to European and ASTM standards
An exclusive Repiper installer TDM can provide more solutions in pipeline rehabilitation than any other provider in Australia. The Repiper is a flexible system that is cured by steam to speed up the installation process. A Repiper technology is a specialist tool that allows TDM operatives to install pipelining to defects, joints and junctions that are usually deemed inaccessible for installers. The tool can be pushed or pulled into place and installed both vertically and horizontally.
The flexibility of the Repiper tools enables lining installations of the entire plumbing system, including pipes followed by a bend or angle.
The product has many variations to different sizes in both Y's & T's. For example, a 100mm line by 50mm tee is available, as is an 80mm by 80mm" Y and virtually every other combination.
TDM carry multiple sized shaped packers, and tooling to allow installation to be completed for all tie-ins that can't be rehabilitated with other CIPP technologies.
The Drain Man continue identifying world's best practice, we actively promote innovation to achieve long life, fit for purpose competitive pricing and installation.
Junction & Connection lining
Junction relining is another trenchless relining solution TDM can offer for repairing junctions and connections – (the point where the connection branch meets the main sewer or stormwater pipe)
Junctions and connections can be problematic areas for root intrusion, infiltration, and exfiltration. TDM has three methods for the trenchless rehabilitation used to permanently seal and reline junctions and connections that our experts can adapt to suit the project requirements.
The three installation methods are similar in terms of installation; however, having three different technologies gives us versatility and enables TDM to select the best method for your project.
The installation techniques are similar, whereby a packer or bladder that a resin impregnated liner sock-fit onto. However, each method is different in cure times, resins, pipe lining materials and installation methods.
The installation consists of a packer or bladder that a resin impregnated liner sock is fitted onto. The packer is positioned in place in the main drain. Once the packer has reached the junction, the packer can be manoeuvred for proper alignment within the branch. The packer is then inflated using air pressure to hold the liner into position whilst it cures.
