520			_aDescribes the way in which moisture can enter the space below a suspended floor. This can rot the timbers with potentially disastrous consequences. In old properties the greatest risk is from rising groundwater and in new houses the danger is from construction water drying out. It concludes that the best option for reducing the moisture content is to increase the crawl space ventilation rate. The minimum ventilation rate required in an under-floor space has been calculated for a range of conditions. References.
