How can you tell how damp walls are?

In this presentation Geoff Hunt shows you how different patterns of moisture meter readings can inform you of what might be happening in the wall. By adding in other observations we can arrive at a reasoned conclusion.
GEOFFS MUG
Working with Gloria Daniel and artist Yani Ali from the Big Tomato Company, Surveyor Geoff Hunt curated images of four of the most iconic tools of the profession; the tape measure, note book, moisture meter and distance meter. Crafted in their Stoke on Trent workshops from fine Staffordshire bone china these mugs embody the traditions that shaped the profession and made to grace the desk of many proud surveyors following that path.
