With Sinkholes On the Increase, is it Time for a Drain Survey?

In August a huge, 40ft sinkhole opened up on the Mancunian Way in central Manchester. It is likely to cause traffic disruption for months to come. The explanation for all this may be erosion from persistent and heavy rain. However, another common cause of sinkholes is deteriorating sewage or drainage pipes. In fact the two possibilities are intimately linked: increased rainfall can cause ground movement that in turn can damage drainage networks.

Sinkholes can open up close to extensive building developments because water runs off onto the surrounding land rather than soaking into rocks below. Another reason why a drain survey can be an essential tool in either the prevention or diagnosis of drainage problems.

The implications of drainage issues for householders and businesses can be severe. Obviously a 40ft sinkhole is a rather dramatic example, but drain blockages and collapsed sewer pipes are enough of a cause for concern. Even persistent drain clogging can be disruptive even if its effects aren’t immediately catastrophic.

Drains are an essential part of a working infrastructure and people expect them to work properly and efficiently on a day-to-day basis. Which is why it often comes as a shock when they don’t.

The drain survey is a crucial investigative tool when it comes to drains. Sonar drain tracing and CCTV cameras allow us to thoroughly inspect and assess a drainage network. We produce a comprehensive report from our findings, including a DVD of the CCTV footage. Where we’ve discovered deterioration or other drainage problems we then provide a clear set of recommendations in an action plan.

We can do all this with minimum environmental impact, providing you with crucial knowledge about your drainage network and pointing the way forward for whatever remedial action needs to be taken. It’s often worth taking steps now to prevent worse things happening later.

No one wants to be surprised by a sinkhole.
