Dry Standards
Wood Moisture Equivalent (WME)
- For Timber and Timber Framing
- Between 9% and 15% is Dry Standard
Gyprock Scale (GS)
- For Gyprock Sheeting
- Less than 0.6% is Dry Standard
- Less than 12%WME
Moisture Content (MC)
- Concrete
- Less than 4.5% on a Concrete Moisture Meter (Tramex CME 4) is Dry Standard
- If resilient flooring is being installed, drill a 19mm wide hole in the concrete slab, install Tramex sleeves to the depth of 40% of the slab. 1 sleeve per 10m2. Leave the sleeve in the slab for 72 hours before taking a Hygrometer reading which should be between 21 & 27deg & under 75% RH
- Carpet
- Less than 15% is Dry Standard
Heat Drying
- Starting temperature & humidity to be recorded
- Room temperature to be recorded at every attendance
- Temperature gain to be recorded at every attendance
- Humidity changes to be recorded at every attendance
- Surface temperature to be recorded at every attendance
- Heat Drying an area = Temperature Gain to the surfaces/room & Relative Humidity Reduction
- Target drying = Temperature Gain to the surface & Relative Humidity Reduction
