  • Polypropylene Tile & Stone floor underlayment for crack isolation
  • Protects tile floors from cracking due to substrate movement
  • Center layer design provides channels allowing moisture to escape
  • Made of three layers of polypropylene for mechanical bonding, vapor management and Sheer Stress control to neutralize stress caused by substrate movement
  • Premium polymer-modified thin set mortar required for installation, no premixed mortar or mastic
  • Protects tiled floors from cracking as substrates move or settle
  • 3.28 in. W x 82 ft. L (25 sq m / 269 sq ft.)
  • Red primary layer with white fleece bottom layer
  • The underlayment features a patented Shear Stress Control® system with nonwoven anchoring fleece to neutralize stress caused by movement in the substrate

PROVA-FLEX® is a durable, lightweight uncoupling membrane that provides crack isolation protection to concrete or wood substrates. The underlayment consists of three layers: a top layer of woven polypropylene mesh, a central sheet of polypropylene, and a bottom layer of non-woven polypropylene. The top layer provides a mechanical bond between the cured thin set and tiles, and allows for the efficient spread of thin set mortar; the central layer includes hollow studs for holding modified thin set mortar; and the bottom layer, which is secured with a polyolefin-based adhesive, provides Shear Stress Control by neutralizing stress caused by substrate movement. This underlayment is lightweight and is an easy-to-install alternative to backer board.
