In the not too distant past, should a drainage pipe be damaged and in need of repair, excavation was the general method used by engineers for replacement works to go ahead. This was not only time consuming, it would also lead to quite a bit of disruption in the vicinity of the pipework.

Thankfully, there is now another, more effective, solution within the drainage contractor’s arsenal. Trenchless technology can be used to get to the heart of the matter without having to dig up the area around the pipes.

Drain lining work can be done within a much shorter time frame, and without all the turmoil usually experienced when using the previous ways of working.

The modern liner repair service is just as sturdy and reliable a technique of repairing the pipe than the old method was. In fact, it can really save money for the organisation having to pay for the work to be carried out.

Whatever has caused the pipe to be damaged in the first place, be it subsidence, pressure or root infiltration, trenchless technology can be utilised to provide an efficient form of drain repair.

Speak to your local drainage contractor about the various services they can offer when it comes to drain lining and repairs.

There are a number of reasons why drains may be cracked and damaged, with joints at risk of opening up. These include such things as water infiltration, vehicular traffic, root ingress or ground movement.

In order to find a solution to the issue, you may not necessarily need to excavate the area around the drain, but this will be determined by the drain inspection.

The defective area in the pipe will need to be repaired, if not replaced, and so the following structural and non-structural techniques are now available to carry out any of these repairs.

Patch lining and chemical grouting are non-structural repair techniques to seal the area of water ingress, which, when left to continue, could severely damage a drainage system.

For more extensive problems, and more widespread defects, structural repairs like soft lining is used. In extreme cases the pipe may have to be replaced, but this method of installation is an excellent option to consider instead of the need for traditional excavation work.

You can be sure that these modern methods are both quick and efficient, not to mention being very cost effective too. So for the minimum amount of disruption, get in touch with a reliable drainage contractor today.

While in some situations excavation is still unavoidable, there are now far more repair techniques available to contractors that do not require a road or street to be dug up in order for drain repairs to be carried out.

This means that the latest processes are time-saving and efficient so that the drain does not always have to be exposed so that the defective area can be accessed by engineers. Whether it is a non-structural or structural issue with the drain, the following techniques are commonly used to prevent the need for excavation.

Pipes can now be repaired and cracks or holes mended through the use of patch liners which seal the affected area. For non-structural work, this technique is widely used, along with patch grouting which can reduce the chances of the drain failing in the future.

When it comes to structural repairs, and a more widespread issue, soft lining is often used to repair the pipe damage. Excavation is sometimes required though, especially if the pipes do eventually need replacing.

These techniques are put to good use by the drainage contractor and where it is possible to prevent traditional dig repairs, liners can prove to be extremely cost-effective.

How does a CCTV Drain Survey Help?

Many people don’t realise that they have a drainage issue until they have a flood or until they notice a strange smell. Fortunately, both these things can be looked at by drainage experts who will be able to diagnose the problem and offer a suitable solution.

Because the drains leading away from the home are underground, many people disregard them until they have a problem. This means that the consequences of a drain blockage can be severe. Unbeknown to the homeowner, if their drains were checked on a regular basis, most of the problems that cause drain blockages could be solved easily and quickly.

Drainage engineers can easily diagnose potential drainage problems by conducting a CCTV survey. As part of the survey, the drainage professional will insert a CCTV camera into the drain so real time images of the drain can be viewed on a computer screen. The drainage professional will then analyse the images, looking for causes of potential blockages and looking for damage to sections of the drainage pipe.

If a problem is found, in most cases a repair can be undertaken that does not need excavation, as the drainage company will use a drain liner, which can be inserted into the drainage pipe to repair the damage.

If you have a blocked drain, drain inspection works will need to be undertaken to find the cause of the blockage. Drains can be blocked by a number of different things, from incorrect items being put into the drainage system, to roots which find their way into the drain and cause a blockage.

During a drain inspection, drainage contractors will usually perform a CCTV survey of the drain so they can visually inspect the problem. A camera is inserted into the drain and then pushed into the drain section by section, relaying real-time information back to a computer screen. The data is recorded and collated and the images can be played back a number of times to inspect the integrity of the pipe. The blockage may be easy to spot and hence can be dealt with easily using drain jetting, however, if there is damage along the length of the pipe, the problem may need to be assessed further to see what necessary course of action should be taken.

In some cases when there is damage along the section of the drainage pipe, the pipe can be fitted with a liner. The liner will allow solid and fluid matter to flow freely again and hence restore the integrity of the pipe. The best thing about a liner repair, is complete excavation of the pipe is usually not required. In some instances, when a liner is not suitable, the pipe will need to excavated and a new section fitted.
