Schluter®-DITRA and DITRA-XL are specifically designed for ceramic and stone tile installations
3.5 mm (1/8") Thickness | 30 m² (323 ft²)
DITRA and DITRA-XL provide uncoupling to prevent cracked tile and grout.
Made of polyethylene, DITRA and DITRA-XL serve as a waterproofing layer that protects moisture-sensitive substrates, such as plywood/OSB. Free-space on the underside of the matting provides a route for excess moisture and vapor to prevent damage to the tile layer above. DITRA and DITRA-XL perform all these functions while still providing adequate support/load distribution for the tile covering.
