DITRA Uncoupling & Waterproofing Membrane

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.

Features & Specifications

• Provides uncoupling, waterproofing, vapor management, and heavy load distribution to ensure the durability and integrity of tile installations
• Quick and easy to install on top of concrete, plywood, OSB, gypsum, existing vinyl floors, structural planks, sub-floors, and radiant heated floors
• Convenient tile underlayment alternative to cement backer board or plywood
• Use DITRA for ceramic tile installations over single layer plywood or OSB subfloors on joists spaced up to 19.2" o.c.
• DITRA is only 1/8" (3.5 mm)-thick to provide the thinnest possible assembly without sacrificing performance
• DITRA features cutting grooves for precise cuts and air release vents at the corners of the cutback cavities for faster filling
• Use DITRA-XL for ceramic tile installations over single layer plywood or OSB subfloors on joists spaced up to 24" o.c.
• DITRA-XL is 5/16” (7 mm)-thick to create an even transition between typical 5/16” (7 mm)-thick tile and 3/4” (19 mm)-thick hardwood flooring
• DITRA-XL is ideal for installations requiring greater movement accommodation, such as applications using natural stone tile, large-format tile, etc.
