Do Sewer Linings Work?
Parts of the drainage and sewer systems in the UK are considered old and antiquated. Age is clearly a factor that leads to their breakdown, but even modern drains can be become damaged and need repair. As well as age, incorrect groundworks and installation play a part in how well a drain responds to increasing pressure placed on it. Over time, tree root ingress can be a problem too, leading to damage that can be expensive to repair. Is a sewer lining the answer?
What is a sewer lining?
A sewer liner is impregnated with a resin and then inserted into the drain, sealing the inside walls of the drain to prevent leaks and further damage.
How were sewers and drains traditionally repaired?
When a drain collapses from tree root ingress, age or poor installation, the only way to fix the drain used to be replacing the entire pipe. This meant that the ground, whether that was someone’s garden, driveway or a highway, needed to be dug up. Whilst the result was excellent, it took a long time to excavate the site. It was also noisy and messy but, more than that, it was costly.
Are sewer linings the answer?
Many people think so. Known as a no-dig technology, where a drain is detected as being weak or there is damage detected as a result of root ingress and so on, the sewer lining system can be easily and quickly deployed. A new but tried and tested technology, the benefits of opting for a new drain lining are many. For example, there is no need for weeks of roadworks or diverting traffic in order for excavations to take place. It is far less messy and noisy too. But a sewer lining is also known to be effective. Effectively, a pipe within a pipe is created which forms an effective seal against any further damage.Perfect for lining over damage and preventing it from getting worse, sewer lining is also great for helping old sewers and drains stay in great working order. Better still, you get all these benefits with only one hole needing to be dug, if at all!
