Cured In Place Pipe – or CIPP, is a technique for carrying out pipe repairs without having to dig a trench to access the pipe. Across the Southampton area, wherever a drain or sewer is damaged, we can offer our CIPP service to achieve a fast, cost-effective repair.
The CIPP process is also called relining, and can be used with pipes of varying sizes. First of all we’ll survey the job and map any existing branch connections that will need to be reopened once we have put the new pipe liner in place. We’ll usually use CCTV to do this.
Using the CIPP process, we are able to create a new pipe within the existing drain or sewer, without all the disruption of digging down to access the pipe which might mean closing roads and disrupting Southampton traffic.
Instead, we use a liner soaked in resin that is inserted into the pipe. When the liner is in place inside the pipe, we reverse it and force it up against the inside of the existing pipe. We use air pressure or water jets to achieve this. The resin is now in contact with the pipe, and just needs to cure (harden). Once the hardening process is complete, we have effectively inserted a new pipe inside the old one.
Next, we consult the survey map we made at the start of the job, to see where the connecting pipes are. Then we use remote cutting technology to reinstate the connections by cutting through the liner at the correct points. The sewer, culvert or drain can now function normally. If the break is a large one, more than one CIPP patch can be used.
The resin can be made to harden in several ways. The three methods we use are:
Hot water is the original method for curing pipe liner. The liner is initially inflated using cold water, but our engineers then put hot water into the system. The heat cures the resin-soaked lining and seals it to the pipe. Once this process is complete, we cool the system down again with cold water.
Alternatively, we can use UV light to line a pipe with a fibreglass lining. To do this, we push air into the lining which inflates it, and presses it up against the sides of the pipe. Then we use a “light train” which emits ultraviolet light, and pull this through the lined pipe. The light cures the pipe lining.
The other technique we use is steam curing. Along with the steam, we use pressurised air. The liner inflates and pushes against the walls of the pipe, while the steam travels along the length of the liner. We then cool the pipe, to prevent the liner shrinking. The steam process tends to be faster than the hot water curing process, so it’s a good choice when you have a very urgent repair to be completed.
Businesses across Southampton are choosing CIPP repairs because they cost less, and are completed more quickly, than traditional open trench pipe repairs. We have in-depth experience of CIPP repairs and technology, so we can offer expert advice and accurate cost estimates.
