RedLINE®100 - Situra Inc



RedLINE®100 waterproof expansion joint system is used for waterproofing expansion joints in structures, such as commercial and industrial buildings, parking garages, tunnels, etc. RedLINE®100 is specifically designed to accommodate building movements, up to 4” [100 mm] under hydrostatic pressure. RedLINE®100 can be installed in variety of roofing and waterproofing membrane systems, these include Built-Up-Roofing, Coal Tar Pitch, Modified Bitumen, Hot Rubberized Asphalt, Spray Polyurethane Foam, Liquid Applied Membranes and Epoxy Resin.

RedLINE®100 is supplied directly to the job site in a roll with all detail work done and seamed together by a proprietary vulcanizing process, which results in monolithic and elastic seamed joints. Seaming can also be done on site if required.

The advantages of using RedLINE®100 include the elimination of wood curbs, metal components such metal flashing, nails and screws, caulked or glued seams resulting in significant labor savings. The flat profile of the RedLINE® expansion joint also does not obstruct the flow of water to drainage resulting in the elimination of ponded water. RedLINE®100 is manufactured from a saturated elastomer which is chemically stable and has excellent resistance to the effects of weathering.

Hydrostatic Pressure Limit: Working Pressure in Column of water is 33 ft [10 m].
