摘要:
A method of seaming polymeric composite pieces to form a unitary cover which is impervious to the weather is disclosed. The method comprises assembling one or more pieces of a fused composite covering having a weatherable side and a non-weatherable, fusible, side to form a narrow seamable opening; fusing a tape over the seamable opening, and then filling the narrow seamable opening with a weatherable caulk to cover any remaining exposed non-weatherable material.

A hold down device for multi-layered roofs. The hold down device can be modified to afford a water leak detector. A method of using the devices in securing a multi-layered roof is also disclosed.
摘要:
A method of detecting leaks in a multi-layered roof system comprising ejecting a tracer gas and a propellant gas under a water-impermeable membrane of a multi-layered roof system and detecting any escape of the tracer gas on the surface of the roof, which detection is indicative of a break or opening in the water-impermeable membrane.

A hold down device for multi-layered roofs. The hold down device can be modified to afford a water leak detector. A method of using the devices in securing a multi-layered roof is discussed.
摘要:
Ponding is eliminated or substantially reduced on flat roofs by employing a closed cell, thermally insulating foam above the water barrier layer and varying the thickness of the closed cell foam to displace at least a majority of water which might accumulate in areas subject to ponding.
摘要:
What is disclosed is a method of localizing leaks in roof structures and novel penetrating devices utilized for that purpose. Also disclosed are methods of manufacturing roof structures and methods of repairing roofs. The penetrating devices also have the capability of leak detection when used in conjunction with a barrier layer in a roof structure.
摘要:
This invention deals with a device which is useful for the securing of roof structures, especially laminar type roof structures wherein an integral, obstensibly waterproof, covering is used as part of the laminar structure. It also deals with a unique method of detecting leaks in roofing structures which allows the location of such leaks with a certain preciseness by using the fastening devices of this invention as points of reference.
