wedi S-Dry Waterproofing Membrane Sheet – 50 in. x 25 ft. & 80 in. x 16 ft. XL

wedi S-Dry Waterproofing Membrane Sheet is designed for large-surface waterproofing in tiled shower and wet-area installations. It is used to cover wall surfaces and other substrates in a wedi S-Dry shower system, and it can also be used over mortar bed installations where a sheet-applied waterproofing layer is needed before tile is installed.

This membrane helps create a continuous barrier that protects underlying construction from moisture intrusion while preparing the surface for tile. Because it comes in roll form, it is well suited for covering broad areas more efficiently than small-format waterproofing components.

Two roll sizes are available to help installers match the membrane to the layout of the job. The 50 in. x 25 ft. roll provides 104 square feet of coverage, while the XL 80 in. x 16 ft. roll provides 106 square feet of coverage. That gives contractors flexibility when planning wall coverage and other wet-area sections.

For merchandising clarity, this product should be positioned as the field membrane layer within the wedi S-Dry waterproofing system. Accessories such as tape, corners, and seals should be cross-sold to address seams, penetrations, and transitions.

wedi is a family-owned German company that invented the original wedi Building Panel in 1983—the first inherently waterproof tile backer board. Today, wedi engineers complete waterproof shower and wet-room systems, including building panels, shower bases with integrated drainage, niches, curbs, sealants, and accessories designed to work together as a modular system. wedi manufactures in Germany and Batavia, Illinois, and backs its systems with a 10-year warranty (with longer coverage available for registered projects installed by wedi PRO certified installers).
