Abstract:
This study was performed on 42 floor slabs where the moisture was measured at several occasions and the effect of cast in under floor heating was evaluated. A simulation model of moisture redistribution is present.Major finding was that the drying time decreases when the floor heating is started early under the drying process and moisture measurement should be made right between the heating pipes at 40% of the depth of the concrete slab.There seems only to be a small risk of enhanced moisture conditions in the wood flooring if the underfloor heating is turned off during the first year.
