CIPP Relining and Repair
If your drains are cracked or deteriorating, it is only a matter of time before you will be facing serious drainage problems. Damaged pipes put your property at risk of sewer flooding, leaking, blockages, foul odours and water egress that can contribute to subsidence — all issues that get worse with cumulative wear and tear.
So, it is obviously essential to get damaged drains and sewers repaired without delay. But digging up and replacing large sections of pipe can be inconvenient, not to mention costly. Fortunately, there is another way. At Lanes, our default position in the vast majority of cases is to install a cured-in-place pipe (CIPP) 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 pipe interiors without the need to dig. (No surprise that this is also known as ‘no-dig technology’). Whilst resolving the immediate problem, CIPP also heads off the chance of further issues in the repaired pipe for years to come.
Lanes has many years’ experience in delivering this technology, so you can always rely on us to provide the best possible results with the least possible fuss. (Read about our latest ultra slim-line reline solution here.)
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 inside the pipe, the 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 cured or hardened. This creates a new pipe within the old pipe, restoring the integrity of the drain or sewer.
Once the CIPP liner has been installed, any lateral (branch) connections mapped prior to the lining being fitted, are opened using advanced robotic cutters.
Using this CIPP method, we rehabilitate sewers and drains from 50mm to 1,800mm in diameter, accessing the pipe from manhole chamber to manhole chamber. For localised repairs or short sections of 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 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 use the most appropriate method for each situation.
Applications for CIPP technology
CIPP relining is a multi-purpose solution, so can be deployed in a wide range of commercial, industrial and domestic asset maintenance applications.
How much does CIPP repair cost?
Repairs using CIPP technology are very competitively-priced, though it is not possible to give a fixed figure because each project has to be tailored to the individual application. Contextual factors will include the condition and type of pipe, the size, cure method, equipment required, location, accessibility, etc. Whatever the specification, we ensure that the repair reflects your needs and budget.
How long will the replacement last?
Our lining materials are tested for a minimum of 1,000-hours to ensure that they meet the 50-year design life demanded by the WRc (Water Research Centre). Our liners however have a safety factor of x2, so our solutions have a life expectancy of nearly 100 years.
Installations may also be verified by Exova, the independent testing and calibration service so you can be sure our work meets the most demanding industry standards.
What about vertical pipes, downpipes or chutes?
Our no-dig technology is also suitable 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 where necessary using ambient-cure CIPP liner technology.
By adapting the 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 lined many cast-iron pipes encased in the stone of a building or other structure. Using CIPP this way, allows fast and effective repairs quickly and conveniently, where replacement would have taken days or weeks to complete.
