CIPP Drain Relining and Repair in Portsmouth

CIPP stands for Cured In Place Pipe. It’s a method that allows us to repair drainage pipes without the disruption of digging a trench to get to the pipe. We offer our CIPP service throughout the Portsmouth area, delivering a prompt, professional and economical repair, wherever there’s a damaged sewer or drain.

Job Requirement Survey

The CIPP technique is also known as relining, and it’s suitable for use with a wide variety of pipe sizes. First, we’ll look at the requirements of the job, mapping any currently connected branch pipes. These will need to be opened up again when we have finished putting the new liner in place inside the pipe. CCTV is generally the best method for doing this.

CIPP – How It Works

The CIPP technique allows us to make a new pipe inside the old sewer or drain. The great advantage of this is that we don’t need to open the ground and dig down to get at the pipe. This means there is no need to close roads and cause traffic congestion on Portsmouth’s streets.

The technique involves inserting a pre-soaked liner into the pipe. The liner has been soaked in a sticky resin. Once it’s in the correct position, we reverse the liner and push it up against the walls of the old pipe. We use water jets or air pressure to ensure a tight fit. The resin-soaked lining is now clinging to the inside of the old pipe, and just needs to harden. Once this curing process has finished, the result is that a brand new pipe has been inserted inside the existing one.

Absolutely blown away by the service we received. Took all the stress out of losing our heating and hot water. Highly recommended!

Couldn’t have asked for a faster resolution to our drainage conundrum. Nothing was too much for these guys who were brilliant throughout.

Opening The Connections

The next step is to go back to the survey map showing the connections. Again, we can open the connections without digging up the pipe. We use remote cutting equipment to open them, by cutting holes in the pipe liner at the appropriate points. The drain, culvert or sewer is now able to perform effectively. Even large breaks and holes can be treated in this way, by placing CIPP patches end to end, covering the entire hole.

Hardening The Liner

The liner is soaked in resin which needs to harden or “cure”. We use three advanced methods for doing this – steam, UV light or hot water.

We can use steam, along with pressurised air to fix the lining. These inflate the liner and it is pushed up against the sides of the pipe. The steam curing technique is the most rapid, so it’s an excellent option if you have a repair that must be completed urgently.

Some pipe linings in the Portsmouth area are made of fibreglass, and with these we usually employ UV light to cure the pipe. Special equipment called a “light train” is pulled through the lining. The light train gives out ultraviolet light which cures the lining.

The original technique for curing a pipe liner is the hot water method. Cold water is used first to inflate the pipe, then hot water is introduced. The warmth cures the lining and the pipe is then cooled down again with cold water.

Businesses across Portsmouth 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.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
