This infloor underlay is engineered to prevent cracks and protect shower floor tile and other tiled surfaces in demanding environments. This premium underlayment mat provides reliable waterproofing, crack isolation, and vapor management for ceramic tile, porcelain tile, natural stone tile, glass tile, mosaic tile, and stone flooring systems installed over concrete, plywood, cement board, gypsum underlayment, OSB subfloors, and approved existing flooring surfaces. RedGard membrane by Custom Building Products is ideal for floor installations of any size, including bathroom floors, kitchen floors, laundry rooms, basements, entryways, and heated floor assemblies. Its cost-efficiency makes it a practical choice for both residential and commercial projects requiring durable tile installation solutions.\u003c\/p\u003e\n\u003cp\u003eThis floor membrane underlayment features a reinforced fleece backing that securely bonds to polymer modified thin-set mortar adhesive, and installs without mechanical fasteners such as screws or nails, eliminating the need for traditional cement backer board in most floor applications. The reinforced bonding layer creates a strong bond suitable for difficult-to-bond flooring tiles while saving time during installation. At only 1\/8 inch thickness, this uncoupling mat replaces multiple layers of traditional cement backer board, reducing floor height buildup while saving labor time, material cost, and installation weight. RedGard uncoupling membrane roll functions as both a waterproof membrane and an anti fracture membrane, helping prevent tile cracking, grout failure, and surface damage caused by in-plane substrate movement. As an uncoupling membrane for tile, it effectively absorbs stress, preserving the surface and integrity of the ceramic floor tile.\u003c\/p\u003e\n\u003cp\u003eEngineered to absorb lateral stress and differential movement, this crack isolation membrane helps protect a wide range of floor coverings, including natural stone, marble, granite, travertine, slate, engineered stone, mosaic tile, and stone flooring systems, from substrate expansion, contraction, and minor structural movement. It absorbs stress and prevents lateral stresses from being transferred to stone tiles and other floor underlayment types, helping address existing in-plane cracks within the bathroom flooring tile subfloor. The vapor-proof design limits moisture transmission, making this waterproof flooring membrane suitable for wet areas, steam-prone environments, and moisture sensitive installations. Offering superior protection and stability for your waterproof flooring projects, the membrane performs reliably in standard applications or over challenging substrates. When electric radiant floor heating systems are present in certain rooms, RedGard uncoupling membrane may be installed in adjacent or non-heated areas as part of a continuous flooring layout.\u003c\/p\u003e\n\u003cp\u003eManufactured with approximately 70 percent recycled content, this eco-conscious underlayment supports sustainable building practices while maintaining long-term durability and performance. Its sustainability profile makes it a responsible choice for modern construction and renovation projects. The lightweight roll format allows easy cutting, handling, and layout, making it easy to install for professional tile installers, contractors, remodelers, and DIY home improvement projects. It is compatible with different tile types and supports efficient tile installation when renovating older kitchen tile flooring or upgrading bathroom floor tile areas. RedGard uncoupling membrane is widely used for tile floor renovation, bathroom remodels, kitchen renovations, basement flooring upgrades, and commercial flooring applications where waterproof tile underlayment and crack prevention are essential.\u003c\/p\u003e\n\u003cp\u003eRedGard offers a proven solution for waterproof floor systems, tile underlayment membranes, crack isolation mats, uncoupling underlayments, and moisture barrier flooring installations. By preventing lateral stresses and supporting long-term performance, it delivers reliable results across a wide range of tile and stone flooring applications. Designed to extend the lifespan of tile floors while simplifying installation, RedGard Waterproof Anti-Fracture Uncoupling Floor Membrane delivers dependable protection, stability, and long-term performance for modern tile flooring systems.\u003c\/p\u003e","brand":"Custom Building Products","offers":[{"title":"Default Title","offer_id":44679771586777,"sku":"CRG_M323_9","price":4999.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/4676\/8089\/files\/9pcs_bcc6b76c-67c0-4834-ae28-b8b7080bae99.jpg?v=1753977869","url":"https:\/\/gtdsupply.com\/products\/custom-bldg-products-redgard-uncoupling-waterproofing-membrane-323-sq-ft-roll-anti-fracture-crack-isolation-mat-1-8-inch-thick-9-rolls-bundle","provider":"Global Trade \u0026 Distribution Inc.","version":"1.0","type":"link"}
