Save Money on London Drains: Get a CCTV Survey

We Trace and Map London Drains

Have you ever wondered where that drain discharges to? We’ll find out and show you. We can trace the route or location of a single drain-run, or an entire drainage system and also map it out providing you with a diagram.

Using CCTV pipe inspection equipment and sonar tracing we can easily plot the route of an underground drain or locate with precision above ground the location of that very drain below ground.

With our knowledge of drainage systems and the latest technology drain cameras we find your buried manholes. Don’t worry if it seems like you have no access points. We can easily remove a toilet or install an access cap onto a soil stack pipe to be able to run our camera through the drains and locate the manhole chamber with accuracy. Once we have located the elusive manhole chamber we also undertake any associated ground works and new inspection cover installation to restore the permanent access at surface level.

Do drains need to be cleaned before they are checked with a camera?

It is the best practice and one adopted by professional drain surveyors because this will ensure that any encrustations, spider webs or partial blockages will not obstruct a clear view of the inner walls of the pipe or hide a fault. For problem drain investigations like recurring blockages an initial inspection is undertaken before cleaning to identify the location of the blockage and the nature of the build up.

Drain Tracing and System Mapping - London

Why would you want to trace a drain or map your drainage system?

There are a number of reasons you may need to do so. For example, if you are planning on installing additional drainage which will need to be connected to your existing drainage system or you are planning to build an extension and dig new foundations it is essential to know where your drains are and depth they are at. If you were to inadvertently damage or collapse a drainage or sewer pipe, that could be expensive to repair and cause delays to your project. When constructing a property extension above a local water authority's drain you will also require a build over agreement with them which is something our drain surveys assist in obtaining. Your local council building inspector will often insist on pre and post drainage system surveys to ensure that no damage to your privately owned drainage has occurred during the construction process.

Are you landscaping the garden and planting trees? Again, when they grow large their roots can infiltrate and crack or break the drain - costing to repair with drain relining to prevent further root growth within the pipe. If you know where your drains are you avoid any potential problems.

Believe it or not, there is a real advantage to knowing the configuration of your properties drainage system and where it connects into the main drainage and sewer system. There is also value in being able to provide that information to any future purchasers of your property or save on time related charges when having your drains unblocked.
