摘要

A penetration pocket assembly and method of forming same for sealing the joint between a membrane covering a roof structure and an element projecting therethrough. A rigid ring is placed inside a polymeric boot which is equipped with an upper and lower flange. The ring is positioned so that an upper edge fits into the boot upper flange. The ring/boot assembly is then located on the membrane surrounding the projecting element. The ring is sealed to the membrane with an adhesive and a pourable waterproof sealant fills the area within the ring, bonding to the inside surface of the ring, the boot upper flange, the exterior surface of the projecting element, and the membrane.
