A method of pulling a sheet of flexible material includes forming a row of a plurality of lengthwise slits in a sheet of material; providing at least one pull device; and providing at least one cable winch. A tubular pull rod is inserted through the plurality of slits. A pull device preferably includes a first pull strap, a second pull strap, a spreader bar and a strap ring. First and second pull devices are positioned near opposing sides of the sheet of material. First and second winches are secured to the floor on one sidewall of the building. The sheet of material is laid on the floor at an opposing sidewall of the building. Cables from the first and second winches are pulled over struts in the building and secured to the first and second pull devices. The sheet of flexible material is pulled to the one sidewall.

Provided are roofing membranes comprising pressure-sensitive adhesives particularly adapted for use at cold temperature, and methods for using same. In one aspect, the disclosure provides a roofing membrane comprising: a bituminous sheet having a lower bituminous surface and an upper bituminous surface; and a non-bituminous cold-temperature pressure-sensitive adhesive disposed on the lower bituminous surface, the upper bituminous surface, or both, wherein the cold-temperature pressure-sensitive adhesive has an average adhesion of at least 10 lbs/ft (146 N/m) at 2 C. as measured by a two hour T-peel test.

A method includes obtaining a first membrane; obtaining a second membrane; wherein the first and/or second membrane include an uncured silicone edge portion; installing the first membrane above a roofing substrate; installing the second membrane above the roofing substrate; overlapping the first membrane and the second membrane; curing the uncured silicone edge portion; and providing a lap seal between the first membrane and the second membrane.

A thermoplastic single ply protective roof covering may have two pressure sensitive rubber-based adhesive backings. These dual-adhesive backings may be used to provide for a non-heat welded seam having a combination of good seam strength and fire performance.

A roofing membrane may include a main body, a first material, and a second material. The first material may be bonded to the main body and positioned toward a first edge thereof. The second material may be bonded to the main body and positioned toward a second edge thereof. The second edge may be positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body. At least one of the first material or the second material may include a first reactive material of a chemically reactive two-part cure system that is configured to chemically react upon contact of the first reactive material with a second reactive material of the chemically reactive two-part cure system.

The invention provides a detailing process with waterproofing membrane parts and prefabricated accessories which includes below steps: place the first layer membrane on the base template while the edge of the first layer membrane beveled; place the edge of the second layer membrane partially overlapped with the edge of the first layer membrane and then fix the position, and place the membrane edge with bevel to the surface of the second layer membrane fittingly; the edge of the second layer is beveled; and the second bevel is directed towards the direction of the first layer membrane. Press together and make the second chamfered surface fixedly connected to the surface of the first layer. The waterproofing parts connection based on this process has high structural strength, a more complete and unified appearance, improves the waterproofing performance of the parts and accessories, and significantly enhances the service life of the membrane.

A roofing membrane may include a main body, a first material, and a second material. The first material may be bonded to the main body and positioned toward a first edge thereof. The second material may be bonded to the main body and positioned toward a second edge thereof. The second edge may be positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body. At least one of the first material or the second material may include a first reactive material of a chemically reactive two-part cure system that is configured to chemically react upon contact of the first reactive material with a second reactive material of the chemically reactive two-part cure system.

A method includes obtaining a first membrane; obtaining a second membrane; wherein the first and/or second membrane include an uncured silicone edge portion; installing the first membrane above a roofing substrate; installing the second membrane above the roofing substrate; overlapping the first membrane and the second membrane; curing the uncured silicone edge portion; and providing a lap seal between the first membrane and the second membrane.

A method of installing thermoplastic roof membranes within a roofing system, the method comprising (i) providing a first membrane composite and positioning the membrane on a surface of the roof system, where the membrane composite includes a-protective film (ii) providing a second membrane composite and positioning the second membrane composite adjacent to the first membrane composite in an overlapping manner to provide a pre-seamed lap, where the second membrane composite includes a protective film (iii) heat welding the first and second membrane composites together at the pre-seamed lap, where heat welding incorporates a portion of the protective film of the first membrane composite into the seam; and (iv) removing the remaining portion of the protective film from the first membrane composite.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.
