Stop the Rot

To prevent the deterioration of timber floor construction adequate ventilation must be provided to the sub-floor area. Moisture from the ground must be prevented from causing undue dampness or deterioration of building elements. Volume 2 of the Building Code of Australia (BCA) states that "clearance between the ground surface and the underside of the lowest framing member must be not less than 150mm." Clearance must also comply with any "Manufacturers Installation Requirements", for the flooring material used.
