Why having a damp free home is important

Suspended wooden floors above bare ground are a major source of internal moisture. Evaporation from the ground can add 40 litres of moisture a day to the average home (BRANZ: Builders’ Mate, Feb 2014). It’s important to keep that water in the ground, where it belongs, by installing a groundsheet (made of heavy polythene). For more information, see Energywise How to tackle dampness.
