Gruen Waterproofing Membrane - High-Performance Tile Underlayment

The Gruen Waterproofing Membrane Roll is a high-performance tile underlayment designed to provide superior moisture protection in bathrooms, showers, and flooring applications. This heavy-duty polyethylene membrane forms a watertight barrier, preventing water and vapor infiltration that can lead to mold, mildew, and structural damage. Its flexible, dual-sided anchoring fleece ensures maximum adhesion to thin-set mortar, making it an ideal choice for tile installations over cement board, drywall, plywood, and concrete substrates. Whether you're a professional tile contractor or a DIY renovator, this crack-resistant waterproofing layer enhances the longevity and durability of tiled surfaces in wet environments.

Engineered for easy handling and installation, the Gruen Waterproofing Membrane folds and bends effortlessly to accommodate shower corners, curbless walk-ins, and complex layouts without tearing or delaminating. Its heavy-duty composition resists peeling, ensuring a long-lasting, leak-proof bond under tiles. Suitable for use with ceramic, porcelain, stone, and mosaic tiles, this high-strength underlayment membrane is compatible with various tile adhesives, making it a versatile and essential component in any bathroom remodel, shower waterproofing system, or flooring project.
