Sewer Relining, Renovation and Rehabilitation

Expert sewer renovation to restore and maintain the efficiency of your sewer systems.

There is good news though. At Lanes, cured-in-place pipe (CIPP) sewer renovation is our default technique in the majority of sewer repairs. It is good because using CIPP (also called no-dig, trenchless or relining technology) allows us to rehabilitate sewers and drains from 225mm to 2,500mm in diameter without digging up land, roads, or pavements.

CIPP relining is an ideal alternative to digging up and replacing large sections of pipe, which can be inconvenient and costly.

At Lanes, our default position in the vast majority of cases is to install a cured-in-place pipe repair or liner, which is cost-effective and minimises any disruption to your business.

With CIPP relining, we make long-lasting fixes and improvements to sewer pipes and drains without the need to dig, which is why this method is also known as ‘no-dig technology’.

The CIPP process not only fixes the immediate problem, but also heads off the chance of further issues in the host pipe for years to come.

CIPP is often the safest method where there are bends in the pipe, the pipe is longer than 300 metres or is badly deformed so that the liner may snag and rip as it is being pulled through.

It’s important to take advice from an expert drainage solutions provider, like Lanes, who will prescribe exactly the right method for your project.

Lanes has many years of experience in delivering this pipe lining technology, so you can always rely on us to provide the best possible results with the least possible fuss. Call us on 0800 526 488, or fill in our online enquiry form.

What’s involved in CIPP pipe repair?

These ‘no-dig’ or ‘trenchless’ pipe replacement methods involve inserting a liner impregnated with a special resin into a vertical or horizontal sewer or drain. This works for pipes up to 1.8 metres in diameter.

Once placed inside the damaged pipe, the resin-impregnated liner is turned inside out and forced through using either water or air pressure; the liner is pushed out to bond with the interior of the pipe and the resin is hardened using an appropriate curing method, including the application of hot water or ultraviolet light. This curing process effectively creates a new pipe within the existing pipeline, restoring the integrity of the drain or sewer.

Once the new pipe liner has been installed, any lateral connections mapped prior to the lining being fitted are opened using advanced robotic cutters.

Using this CIPP method, we rehabilitate sewers and drains from 100mm to 1,800mm in diameter, accessing the pipe from the manhole chamber to the manhole chamber. For localised repairs or short sections of the drain, we may employ CIPP patch (or point repair) lining. This involves positioning a ‘patch’ (short piece) of CIPP liner which is wrapped around an inflatable packer.

Once in place, the packer is inflated leaving the patch to form a new pipe lining to that section of pipe. Several patches may be fitted end to end to make a longer repair.

Full CIPP relining and patch repairs are equally effective for creating long-lasting solutions with minimal disruption. Our expert team always uses the most appropriate method for each situation – you can read about our latest ultra slim-line reline solution here.

What about vertical pipes, downpipes or chutes?

Our no-dig technology has been shown to provide a highly effective method for vertical pipe and refuse chute repairs, which we undertake for a range of clients such as housing associations, landlords, and property management companies.

Firstly, we survey the pipes with advanced CCTV cameras, then repair them where necessary using ambient-cure CIPP liner technology.

By adapting the CIPP installation technology we use for horizontal drainage repairs to suit vertical pipes, we have helped clients who would otherwise have been facing total pipe replacement with all the costs that would incur.

For example, we have successfully delivered CIPP installations for cast-iron pipes encased in the stone of a building or other structure. Using CIPP this way allows fast and effective repairs of the existing pipe to be completed quickly and conveniently, where replacement would have taken days or weeks to carry out.

With UV lining, our engineers can fix damaged drains and sewers without having to dig up and replace large sections of deeply buried pipes. This method offers some advantages over conventional cured-in-place pipe (CIPP) repair techniques.

How does UV lining work?

The basis of UV drain lining is similar to other forms of CIPP relining: a liner layered with a special resin is inserted into a sewer or drain, before being turned inside out and forced through the pipe by either water or air pressure. The resin then bonds to the surface, creating a new pipe within the old damaged pipe.

The next stage is to cure the resin in the liner. Older methods like hot-cure CIPP involve pumping heated water through the liner at a given temperature for a specified time to cure the material. This can be time-consuming and energy-intensive.

UV lining is quicker and greener, as the resin in the liner cures under UV light from a light train that travels through the pipe. This method cures a liner at a super-fast one-metre-a-minute.

As such, UV lining has become the go-to solution for most drainage repair jobs; you can call us on 0800 526 488 for more information, or fill out our online enquiry form to request a call back to suit you.
