Pipe patching is a new fast permanent solution that is ideal for smaller pipe leaks or cracks. This is becoming the most popular alternative to digging trenches for tree roots, damaged, misaligned or broken pipes.
The process if very similar to doing a full relining except if the installation is in one or two meter lengths to mend the breakages or misalignments. If it’s not economical to reline the entire pipe , then we would recommend using the relining for pipe patch repairs. If several patches are required then relining the entire drain may be better value for money.
How does pipe patching work? Fixing damaged sections of pipes have traditionally meant digging a trench to access the damaged sections. By using the lining as a pipe patch your saving money, time and even better you don’t have to dig a trench.
Step 1: Cleaning the drain of debris. We use our high pressured water jet to clear and clean the drain.
Step 2: CCTV Our CCTV camera is placed down the drain to inspect and measure the area needing repair.
Step 3: Inserting the resin filled liner Now that our pipe is clean and we’ve inspected the area, the liner is cut to length and soaked in our environmentally safe resin and secured to an inflatable bladder that is then inserted into the drain.
Step 4: Position packer into pre-measured location and inflate Using the CCTV, the bladder is guided into place and then inflated.
Step 5: Curing process The patch takes approximately 4 hours to cure. The bladder is then deflated and removed from the drain.
Step 6: Removal and final CCTV inspection Lastly, the patch is inspected using CCTV camera to ensure the patch has set and the repair completed.
Trenchless pipe relining facts:
Patching can work from 50mm to 1200mm diameter pipes.
For pipe section repairs above 225mm in diameter we use triple layer glass matting that is structural to comply with local council regulations.
Relining can be used to repair earthenware, cast-iron, PVC, cement, asbestos pipes and more. Contact us to find out more about pipe patching.
