Abstract
Recently, the troubles such as water leakage have increased due to rupture and breaking loose of the waterproofing membrane covered over the roof slabs consisting of prefabricated roof planks. The authors took actual measurements continuously from Jan 73 of the movement at the plank (cemeted wood chip board) joint, temperature and relative humidity causing the movement for roof plank. Differential transformer, themister thermometer and hydgrometer were used for measurement.
