In Florida doing surveys(assessments) and I find that most surveyors(inspectors) need more education and training. Keep up the good work👍

Hi Geoff, thanks for this information. Could you provide some information regarding the render detailing and when it is possible to render over the DPC without causing internal damp penetration? Thanks.

Hi. Thanks for watching. In terms of the wall I only used it for demonstration purposes. I happen to know I have a higher spot on that wall as its a single skin garage wall with no DPC. Technically speaking you can put render on a cavity wall because the inner should be separated by the outer. That's not everyone's point of view and lots of people quote the 150mm minimum clear brick to ground level because it is thought that covering the dpc with render creates a bridge. In my experience it does bridge but it takes a long time to become manifest. It's different for solid walls where keeping the dpc as clear as possible is the best plan. Water is a complex chemical so if it can get in it will. Check out NHBC details as they are generally accepted as industry standard even if they don't care to check its built like that!
