The instruments are also placed at the same height as the applied load to measure wall deflection. The load and deflection data are recorded concurrently until the wall assembly fails. The allowable moment, M ASD, is determined by multiplying P ASD, the allowable horizontal load, by h wall, wall height (M ASD = P ASD * h wall ).
Electrical Moisture meters for damp diagnosis – oh yes. A thing that raises an eyebrow amongst some independent surveyors is the way we so called 'specialists' seem happy to diagnose rising damp, or damp of any kind, using nothing more than our eyes and a conductivity moisture meter.
