How Do You Reline a Drain Pipe?

How do you reline a drain pipe UK

When you need to reline a drain pipe, you should start by finding where the broken part is. You can do this by looking for signs of damage such as extra green grass or wet patches. Then, dig six inches beneath the broken pipe to create space to make repairs.

UPVC relining sleeves

UPVC relining sleeves are a cost-effective way to improve a drain’s condition. The process involves cleaning and de-scaling the pipework. To remove any scale, slit deposits, or other obstructions, high-pressure water jetting is used. Once the pipework is free of blockages, UPVC relining sleeves are installed using air inflation. The relining sleeves are left to cure for up to three hours before being removed. During this time, an inspection pit is cut to determine if blockages have been cleared. Once the relining process is complete, the new section is cleaned to remove any excess resin solution.

Unlike other pipe repair methods, relining is less disruptive and cheaper. It also can increase the life span of the pipe by up to 50 years. It is also an environmentally friendly solution. Once the pipe is lined, it is protected against the damaging effects of chemicals and rust.

GFRP UV pipelining

GFRP UV pipelining is a unique technique that involves inserting a GFRP pipe liner into a drain or sewer. The lining is inflated with free air, and then pulled into place. A UV Light Train with built-in CCTV is then pulled through the pipe, igniting the resin and curing it. The resin will be as strong as new once it reaches the full cure point. This method is suitable for pipes that are long or deformed. Aside from its durability, UV pipelining is a cost-effective solution for repairing drains and sewers.

This environmentally friendly method is available to local authorities, industrial plants, and commercial businesses. It is extensively used to line gas, chemical, and sewer pipes. The lining process can be completed with minimal disruption. The process is easy and portable, and the pipe diameter will not be reduced.

UV lining is the fastest and most cost-effective solution for repairing pipes and sewers. With a cure rate of one metre per minute, the process will be complete in a matter of hours. This method also reduces the risk of pollution from contaminated water.

Heat cured lining

Drain lining is a highly effective method of drain repair. It involves the installation of a polymer sleeve that bonds with the inside surface of the drain pipe. It is like building an extra pipe inside the existing one. The liner is then carefully fed into the drain and moves to cover the interior surface. Once in place, an airbag in the liner pushes it outwards towards the surface of the pipe.

This method is more commonly used on industrial sites or larger commercial premises. It works by lining the entire length of a drain. This method covers multiple defects, particularly on large diameter pipes. Unlike other methods of pipe lining, heat cured lining is not a permanent solution.

Heat cured lining uses different methods of curing the resin. One method uses UV light to cure the resin. Another method is drag in. Drag in methods are best for smaller diameter manhole to manhole ambient cure applications. Drag in methods are also used for UV Lining. For this technique, the liner is manufactured from glass fibre and impregnated with polyester resin. The UV light train then pulls through the liner, curing the resin.

Inversion lining

Inversion lining is a method used to repair damaged drain pipes. The process requires one access point, which is usually a manhole opening. A liner containing a resin is then inserted into the pipe. The liner is compressed and filled with air and water, which pushes the resin against the contours of the pipe. The resin is then cured using hot air or water.

The lining procedure is a safe and effective solution to damaged drains. It provides a protective layer, which is resistant to a range of chemicals and extremely high temperatures. The process is simple and quick, requiring minimal disruption to your property. Unlike traditional pipe repair methods, inversion lining creates a new pipe within the existing one.

Once the pipe is cleaned and cleared of intrusions, the lining process can begin. The type of liner used will be decided during this stage. Some pipe lining procedures use flexible liners while others use rigid liners.
