The response of a mechanically anchored waterproofing membrane system located atop a building on the island of Miyako when subjected to strong winds from a typhoon in 2007 was measured, and the relationship between the wind pressure and the behavior of waterproofing membrane system was investigated A waterproofing membrane was constructed atop the roof of a building, and the PVC membrane was fastened by fasteners at a pitch of 600mm. The response of the wind pressure, the billowing height, and the strain of the waterproofing membrane were measured at the site of typhoon No. 12. The maximum wind speed was recorded as 16.8m/s, and the maximum instantaneous wind speed was recorded as 28.1m/s. The waterproofing membrane was billowing and flattering at high wind velocity. As the wind pressure increased, the billowing height and the strain of the membrane increased. The values of these parameters were higher at the edges of the test specimen. The results measured on site had good correlation between the wind pressure and the response of the membrane system at higher wind velocity.
