Gpr is probably known by the layperson where Time Team are using it in regards to archaeology. I never even thought of this until last year when chatting to a client who is an archaeologist that advised of the potential in regards to aiding my damp surveys.

Whilst GPR wouldn’t be used on every damp survey, it certainly has it’s uses in locating culverts, land drains, French drains, wells, basements and cellars that are hidden, and even water. It can also be used for searching for mains water pipes, that perhaps knowbody knows where they go to. It can also be used before excavations are carried out to ensure no utilities are present.

Why did I take the plunge into GPR? It was simply because some of the more complex jobs require that final piece of the jigsaw, and this is the only way to locate the other possible sources of water, that could subsequently cause the damp issues. I have been very lucky in some instances previously, and come across wells, land drains, French drains and culverts, mostly by digging in the right place, or the homeowner has been given some info by the previous owners or neighbours.

See the below GPR (Ground Penetrating Radar) image of a well that was covered over. This would have been virtually impossible to find without GPR, and know body actually knew this well even existed.

How much does a ground penetrating radar survey cost? Depending on the size of the area that needs surveying, and other factors will determine the cost of the GPR survey. Ground penetrating radar will be something that can be built into your damp survey, where needed. GPR can also be used to aid a leak detection surveys when needed, and all drain mapping.

Marked up images of findings can also be sent from site via email to save time where necessary.
