PRESENT SITUATIONS OF WATERPROOF AND DRAINAGE FOR HYBRID STRUCTURES

Abstract

 Generally, we set the waterproof on the surface of structures to prevent ingress of water into the structures. For waterproofing systems, we request higher performance. But we can't set the waterproofs without any errors at all times. We must prepare the drainage systems as the backup of waterproofs to minimize the influences of water infiltration. However, there are many uncertain part with waterproof and drainage. Then we carried out the some investigation about current situation of waterproof and drainage for hybrid structures.
