PVC Pipe Inspection

The initial step in pipe relining involves a meticulous inspection of the drain and sewer pipes using advanced CCTV technology. Thanks to this non-invasive approach, pipe relining experts in North Shore can pinpoint the extent and exact location of any damage, all without disrupting your landscape. It’s like a high-tech detective adventure, revealing hidden secrets without leaving a trace.

Customised Pipe Relining Plan

Sewer pipe relining companies specialise in crafting tailored solutions to suit individual situations. From minor leaks to severe damage in underground sewers, they offer comprehensive and efficient repairs. Swift resolution is guaranteed for minor leaks, with repairs completed in a matter of hours. For more intricate cases, pipe relining contractors will dedicate up to a day or two to ensure a thorough and efficient fix.

Hydrojetting

Prior to initiating the pipe relining procedure, a comprehensive cleansing process is carried out on drains and sewer lines utilizing hydrojetting. This method employs high-pressure water to effectively eliminate obstructions and debris that might impede the proper adhesion of the epoxy resin. By achieving a clean and unobstructed pipe interior, an optimal seal for cracks and leaks is ensured, enhancing the overall effectiveness and longevity of the pipe relining process. This meticulous cleaning step is a crucial preparatory measure, as it sets the foundation for the subsequent application of the epoxy resin, ultimately contributing to the successful rehabilitation and maintenance of the pipelines.

Pipe Relining

The actual relining process begins by creating two small openings in the ground—one at the beginning of the pipeline to be repaired and one at the end. A fabric liner, saturated with epoxy resin, is then pushed through the old pipe and inflated using compressed air. The epoxy resin adheres directly to the old pipe walls and is cured in place for several hours. Afterward, the bladder and fabric lining are removed, and a final inspection, aided by CCTV cameras, ensures that cracks, leaks, and missing sections are appropriately sealed with the epoxy liner.

Curing 

Homeowners can expect standard epoxy resin to fully cure within 12 to 24 hours, particularly with an ambient curing process. However, if you opt for hot water and steam curing, the hardening time can be reduced to just a few hours. Once the epoxy resin is cured, it becomes a strong and durable material, similar to a brand-new pipe. The smooth interior lining created by the epoxy resin ensures efficient wastewater flow without any harmful corrosive substances. Moreover, the airtight and watertight seal formed by the resin prevents leaks that could potentially damage the quality of the surrounding soil.

Final CCTV Drain Pipe Inspection

The final step in the pipe relining process is the crucial CCTV drain pipe inspection. Using advanced technology, a high-resolution camera is inserted into the relined pipe to assess its integrity and ensure a successful lining application. This thorough inspection allows experts to detect any potential issues like misalignments, wrinkles, or blockages. By identifying and resolving these problems promptly, it helps to avoid future complications and extends the life of the rehabilitated pipe. The detailed CCTV footage provides a clear view of the entire pipe system, enabling technicians to verify the quality of the relining work and certify its effectiveness.
