Dye testing for drainage issues

There are many reasons as to why a drainage system may need to be inspected and investigated, such as home buyer surveys, regular blocks, water ingress to cellar or sub floor areas, subsidence investigations or you may need to know where a system runs before building an extension.

Some of the common methods of drainage investigations have been used for hundreds or years, whilst others make use of state-of-the-art modern technology. For example, if you have a reoccurring problem with your drain that is the result of either a blockages or a contractor is pulling out tree roots, then a CCTV survey will be required to fully understand the extent of the damage.

Another method of drainage investigation is dye-testing, where you simply put a bucket of dye into a drain in order to locate a leaking joint or identify and confirm the route of the system. The drain dye is a simple, cheap and effective method and comes in bright colours such as red or blue so it stands out. The dye used is also environmentally friendly in case it runs into a river and so it doesn’t stain your bath or toilet within the property.

If you have water ingress in a basement you can also use dye testing to determine if the leak is from the drainage system. If done correctly this should tell you all you need to know and accurately locate the area of the problem and indeed rule out where it isn’t.

Alternative Drainage’s expert engineers will use a combination of methods to identify and assess the cause of a drainage fault, including dye-testing and CCTV surveys.
