Title:
【発明の名称】構造物表面用密閉シートアセンブリおよびその製造並びに適用方法
Document Type and Number:
Japanese Patent JP2001521840
Kind Code:
A
Abstract:
A sealing sheet (10) assembly bondable to a construction surface comprising (a) an upper layer (14) of a first substance, the upper layer being selected fluid impermeable; and (b) a lower flexible layer (16) of a second substance, the lower flexible layer being bondable to the construction surface. The upper layer and the lower flexible layer are at least partially attached to one another, wherein a combination of the upper layer, the lower layer and the attachment or the partial attachment of the layers to one another are selected such that tensile forces resulting from constructional movements acting upon the sealing sheet result in a local detachment or relative displacement of the upper layer and the lower flexible layer, thereby the ability of the lower flexible layer of transmitting the forces onto the upper layer is remarkably reduced, resulting in improved service of the sealing cover as a whole. The attachment is selected such that a spread of a leakage between the layers via a tear formed in the upper layer is locally restricted.
