If something below the ground could affect what you are doing or want to do on the surface then it is worth getting in touch with us.  We will always be honest and realistic about what can be achieved and if what you really need is someone else, we will tell you.

Our site investigation surveys are non-intrusive, so once we leave a site you could not tell that we had been there.  Our surveys are quiet and safe.
