What Is Pipe Patching ?

    Pipe patching, also known as sectional pipe repair, is an alternative to traditional pipe repair methods. It’s an ideal solution for smaller damaged sections in your piping. Following inspection using a drain camera, repairs are undertaken using a structured pipe patch.

    These patches are often made of fibreglass matting, containing a specially formulated resin. Once the correct length of pipe patch with the resin has been prepared, the drain packer inflates to the structural lining, allowing the resin to cure.

    Pipe patching targets smaller damaged areas in a pipe. The resin solution is installed only on the affected areas in a pipe, which shortens the repair time.

    As only enough resin for each harmed area in the pipe is needed, the cost of the pipe patch repair method will be reduced. As some areas of the old pipe will be left without the new resin liner, they may be at risk of being damaged in the future. This can cause future drainage problems.

    To fix a pipe using the relining method, a section of the liner is cured inside the damaged pipe with a special resin solution that hardens along the pipe. Over time the resin solidifies to the shape of the existing pipe.

    This makes the inside across the entire pipe completely smooth, filling any pre-existing cracks or bumps. A smooth inside will prevent build-ups and blockages in pipes. Also, relining plumbing pipes entirely makes a pipe just as strong or stronger than when it was brand new.

    Although it may cost more initially, inversion pipe relining will avoid any future damage and expenses, it's better to pay for it and do it correctly the first time than carrying out small repairs which end up costing the same amount yet without the same result.

    Benefits Of Pipe Patching?

    It’s fast, permanent and ideal for smaller leaks or cracks in your pipes that don’t need to be completely replaced. Patch repairs are similar to relining, but we install them in one or two-metre lengths to correct isolated breakages or misalignments. We recommend pipe patch repairs if relining the entire pipe isn’t economical. Pipe patching to repair a broken section of a pipe can be an ideal, cost effective solution. However if the pipe requires several patches, relining the entire drain could provide better value for money.

    One of the major benefits of relining pipes is that there is very minimal disturbance to the property. Traditional pipe repair and replacement involve extensive digging which sometimes even extends to your garden, lawns, pathways, etc. Naturally, cleaning and fixing the resultant mess after the job is complete is costly and time-consuming. When you choose the trenchless pipe relining option, you avoid damage to your property besides saving costs.

    Years ago the only solution would be to dig up the pipes and replace the broken sections or create new drains to bypass the damaged areas. This was a fairly straightforward, if labour intensive, process if the pipes were located in a fairly easy to access patch of your property. Issues arose, however, if the pipes or drains were positioned under existing infrastructure such as a concrete slab, paved driveway, house, pool or shed. Even digging up established gardens to replace pipes could mean extensive restoration work was needed after the pipe repair job was complete.

    In 1971 Eric Wood came up with a solution to this often costly problem with the invention of cured in place pipe lining (CIPP). The process of pipe relining involved placing an epoxy impregnated pipe lining inside a broken or leaking drain, inflating the lining so it adhered to the existing pipe and curing the epoxy lining to harden it in place creating a durable new inner layer to the pipe.

    This system has been fine-tuned over the last 40 or so years into the versatile trenchless pipe repair method we use today.

    Patching Processs

    Pipe patching is relatively straightforward, but involves a number of steps:

    • 1.The pipe is first prepared for patching by cutting out all roots and clearing all debris with a jet blaster. A CCTV camera is then used to visually inspect the repair area.

    • 2.A woven fibreglass sleeve is impregnated with a polymer resin.

    • 3.An inflatable bladder called a “packer” is inserted into the sleeve and the sleeve is secured to the packer with elastic bands.

    • 4.The packer is inserted into the pipe and moved into position either by pushing with hollow rods used to deliver air to the packer or by pulling with a rope accessible through a downstream opening in the line.

    • 5.The CCTV camera is again used to ensure the patch is in the proper position.

    • 6.A compressor is attached to the rods and air is pumped into the packer until the sleeve is in full contact with the inner wall of the pipe.

    • 7.The sleeve is allowed to cure in place under pressure for approximately 1.5 hours.

    • 8.The packer is removed, and the sleeve is inspected with the camera a final time.

    Patching Or Relining Which Is Right For Your Drain Repair?

    Pipe patching is ideal for smaller areas of damaged drains as it is very strong with increased structural integrity compared to pipe relining products.
    Pipe relining is suited to longer lengths of cracked, leaking or broken drains. It is durable and can mould with pipe bends and joints without issue.
