Drain repair methods

Drain repairs used to mean that a lot of expensive and time consuming work would have to be undertaken in order to get to the bottom of the problem. Nowadays though there are far simpler ways to deal with things. Drain repairs are more complex than simple things such as drain unblocking, and will need a professional to work on things, maybe someone who offer expert plumbing & heating services or a drainage specialist. Of course, if you’re really interested, you could consider training courses for drain technicians.

Of course, regular monitoring is the best way to avoid needing drain repairs in the first place. But some situations are unavoidable. A drain can become cracked or chipped due to blockages, high pressure, ground movement or traffic moving above. No matter how good the original pipe was, it will weaken over time, and be more prone to damage. The danger comes when people ignore the beginnings of a cracked pipe. Debris can enter the pipe, and block it entirely. Or a cracked pipe in a home’s interior can cause seepage of water into the floors and walls. Either of these things would create a very unhealthy scenario. This is why it is so important to get damaged pipes dealt with.

Fortunately, there is a relatively simple technique available to ‘heal’ a cracked pipe without resorting to replacing the entire pipe! This is called resin pipe lining, whereby a new interior layer is made for the pipe. The composition of the lining can be varied according to the condition of the existing drain, but it is important to consult a trained technician so that they can decide on the right lining for you. The most popular type of lining is the CIPP (cured in place pipe) lining. It is made from a thin felt tube, which has a very thin plastic coating on its outside wall. Once ready to be used, the mixture is activated by pouring a mixture of resin, accelerator and catalyst into the tube. Care must be taken to allow the resin time to soak evenly along the whole length of the liner. Then the liner can be inserted into the existing pipe, and is simply inflated using water or air. Whilst the resin is curing, the liner is held to the wall of the pipe mechanically. Once set, it forms the pipe within the original pipe. CIPP liners can also be used for pipe re-rounding. If a drain has been made with poor quality pitch fibre in the past, it may need to be renewed. The simplest way to do this is to firstly drag a head through the system, which forces the pipe back to its original shape. The CIPP liner can then be inserted in order to help the pipe keep its shape.

Drain patches can also be made to cover a small area if a pipe has only been slightly damaged. Small holes can be sealed with either a patch liner or chemical grouting. Even better is the length of time that these patches can be expected to last, which is up to five years.
