About WallProof

Our purpose

A tool can produce a clear number while leaving the important question unanswered. WallProof explains the connection between the task, the material, the instrument and the decision that follows.

We cover two areas: locating possible objects within walls before intrusive work, and understanding moisture measurements in buildings, timber and flooring. Separate topic routes reflect the different needs of DIY users, installers, woodworkers and homeowners.
