Abstract
This paper describes the development of waterproofing sheet with high venting ability (GFL sheet). GFL sheet has sufficient venting abilities to allow the water in concrete slabs to escape as vapor, and it is as durable as PVC waterproofing sheet. First, waterproofing and venting abilities of GFL sheet were measured. Then, the relation between venting abilities and blistering of GFL sheet was examined. Third, durability tests of GFL sheet were carried out, and the durability of GFL sheet was confirmed. Finally, GFL sheet was tried for waterproofing of the roofs of some real buildings.
