What materials hold up best in a flood?

Below the flood level, use materials that survive getting wet and are easy to clean and dry, such as concrete, masonry, ceramic tiles, fibre cement, closed cell insulation and stainless or galvanised fixings.

Avoid plasterboard, MDF or particleboard, fibrous batts and carpet in areas likely to flood. Put switchboards, power points, hot water and air conditioning units above the flood level. See the QLD flood resilient building guide in Resources.
