• Crack isolation and desolidarization membrane designed to uncouple tile from substrate movement, helping prevent tile cracking and grout joint failure in high-stress areas
• Circular column structure enhances mechanical bonding between thin-set mortar, underlayment, and tile surface for improved adhesion and load distribution
• Suitable for use with ceramic tile, porcelain tile, cement tile, marble, granite, travertine, natural stone, mosaic, and glass tile installations
• Compatible with a wide range of substrates including concrete slabs, plywood, OSB, gypsum, drywall, wood subfloors, cement board, and hydronic heated floors
• Meets ASTM C627 Extra-Heavy Commercial standards, making it suitable for residential, commercial, and heavy-duty load-bearing flooring applications
• Acts as a vapor pressure management solution and is waterproofing-capable when properly sealed, making it suitable for wet and moisture-prone areas
• Ideal for use in showers, bathrooms, kitchens, laundry rooms, balconies, basements, patios, and interior or exterior tile installations
• Easy to cut, trim, and install using a standard utility knife and thin-set mortar, suitable for both professional installers and DIY tile projects
• 1/8-inch thickness supports smooth tile height transitions while providing effective uncoupling and crack isolation for long-term floor performance
• Full roll size of 3.3 ft x 98.5 ft provides approximately 323 sq ft of total material and is cut to length based on your selected quantity, available in 10 sq ft increments from 20 sq ft up to the full 323 sq ft roll

Product Description:

The Profilitec Floortec Uncoupling Membrane Roll is a premium-grade crack isolation solution engineered for superior floor protection and tile longevity. Designed with advanced Lay-Flat Technology, this anti-fracture membrane eliminates edge curling during installation, saving time and effort for professionals and DIY users alike. Manufactured from high-density virgin polyethylene, the underlayment delivers exceptional load-bearing strength and resistance to structural movement. Its translucent composition allows for easy verification of thin-set mortar coverage, minimizing installation errors and voids beneath tile surfaces. The innovative circular column structure enhances mechanical bonding between mortar, membrane, and tile, ensuring optimal adhesion and load distribution. This professional uncoupling membrane is designed to improve tile installation reliability by reducing stress transfer from the subfloor to the finished surface, helping prevent cracked tiles and grout failure in demanding flooring environments. The structured surface geometry increases thin-set contact points, supporting secure tile bonding for long-lasting floor performance in residential and commercial tile installations.

This 1/8-inch thick membrane is ideal for a wide range of applications, including residential, commercial, and light industrial flooring installations. It compensates for lateral shear movement and differential expansion between the tile and substrate, such as concrete, gypsum, wood, OSB, drywall, cement board, hydronic slabs, or plywood. The Profilitec Floortec membrane meets ASTM C627 Extra-Heavy Commercial standards and serves as a reliable uncoupling, waterproofing, and vapor management solution in moisture-prone environments like bathrooms, balconies, showers, kitchens, laundry rooms, and basements. Suitable for indoor and outdoor use, it provides outstanding performance in tile installations over radiant floor heating systems, cracked substrates, or in areas subject to frequent temperature fluctuation. The integrated vapor pressure management design allows moisture vapor to dissipate beneath the tile assembly, helping reduce the risk of tile debonding, efflorescence, and moisture-related floor failures. This makes Floortec an excellent choice for tile floor preparation where durability, movement accommodation, and moisture control are required.

Compatible with a variety of tile finishes, including ceramic tile, porcelain tile, cement tile, granite tile, marble tile, travertine tile, natural stone, mosaic, and glass tile, this uncoupling underlayment ensures durability and stability in wet areas and dry areas alike. Floortec roll can be quickly trimmed and applied using a standard utility knife and thin-set mortar. The roll format allows for efficient coverage of large floor areas while remaining lightweight and easy to handle during transport and installation. Designed as a crack isolation and desolidarization membrane, the Profilitec Floortec system functions as a load-distribution layer that helps manage lateral movement and stress transfer within the tile assembly. It also serves as a vapor pressure management solution by allowing moisture vapor to dissipate beneath the tiled surface, supporting long-term floor performance. When properly sealed, the membrane is waterproofing-capable and suitable for use in moisture-prone environments. It is suitable for residential, commercial, and heavy-duty flooring applications. Whether you're working on a large flooring renovation or a small tiling project, Profilitec Floortec membrane offers a lightweight, easy-to-handle, cost-effective solution for floor crack isolation, uncoupling, waterproofing support, and tile installation stability with long-term reliability and professional-grade results.
