DYSO Extreme antifracture matting is a flexible, uncoupling membrane designed for interior and exterior spaces. Created for installation under large-format ceramics and on floor heating. Maximum resistance to deformation, supporting cracks up to 20 mm. Fully suitable for waterproofing and decoupling substrates in outdoor spaces if placed together with DRY80/ DRY120 It is composed of a closed-cell elastomer layer to absorb in-plane movements of the substrate. Polypropylene fibre coating ensures optimum bonding of C2 S1/S2 cement adhesives used in the adhered membrane installation. The DYSO membrane uncouples the flooring from the substrate and neutralises tension between the substrate and coating caused by movement. The membrane also absorbs cracks in the substrate and prevents their transmission to the tiled surface
