Abstract
The egg-shaped Gas Pavilion was built at the Expor '70 in Japan. As the roofing covering and the extermal surface of this building were united by the curved surface, it was necessary to cover the whole building with the waterproofing layers. In selecting the waterprofing materials, it was necessary to have satisfactory resistance to cracking due to the movement of the substructure, to enable the method of construction to represent the curved surface of this building with good accuracy. The method of construction, using waterproofing sheets of the butyl based unvulcanized rubber, was adopted in order to satisfy the above requirements. An attempt has been made to investigate the loss of the adhesion and the shear deformations of the covering mortar due to the dead weight, and to investigate further creep deformation caused by temperature changes in summer, which may lead to damage if not allowed for in design.
