Product Overview

Schluter-DITRA 150 Uncoupling Waterproof Underlayment Membrane-1/8"x150 SF

Schluter-DITRA is manufactured using high-density polyethylene (HDPE), which does not rot and is highly resistant to solutions containing salts, acids, and alkalis, as well as many organic solvents, alcohols, and oils. Its resistance to specific stresses can be provided if concentration, temperature, and exposure time are known. Schluter-DITRA is waterproof and resists the transmission of vapor. The material is inert, non-toxic, and physiologically safe. Schluter-DITRA also meets the American National Standard for Load Bearing, Bonded, Waterproof Membranes for Thin-Set Ceramic Tile and Dimension Stone Installations (ANSI A118.10) and is listed by cUPC.

Schluter-DITRA's uncoupling function protects the ceramic or stone tile covering from the aforementioned deformations by neutralizing the differential movement stresses between the wood structure and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface. Therefore, DITRA can replace a second layer of plywood in most applications.

Schluter-DITRA 150 - Uncoupling:

Tile has been successfully installed for thousands of years by incorporating an uncoupling layer, or forgiving shear interface, within the tile assembly. Schluter-DITRA provides uncoupling through its open rib structure, which allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface

Schluter-DITRA 150 - Waterproofing:

Schluter-DITRA provides reliable waterproofing in interior and exterior applications. Its polyethylene composition protects the substrate from moisture penetration, which is particularly important in today's building environment where most substrates are moisture sensitive.

Schluter-DITRA 150 - Vapor Management:

The distinguishing feature of Schluter-DITRA is the existence of free space created by the configured channels on the underside of the matting. The free space provides a route for excess moisture and vapor to escape from the substrate that could otherwise cause damage to the tile layer above. Thus, DITRA effectively manages moisture beneath the tile covering.

Schluter-DITRA 150 - Support/Load Distribution:

When placed on a solid foundation, columns or pillars can support tremendous loads. The same physical principle applies to Schluter-DITRA installations. Column-like mortar structures are formed in the cutback cavities of the matting. Loads are transferred from the tile covering through these column-like mortar structures to the substrate. Since DITRA is virtually incompressible within the tile assembly, the advantages of uncoupling are achieved without sacrificing point load distribution capabilities. The ability of DITRA installations to support and distribute heavy loads while preserving the integrity of the tiled surface has been verified through extensive laboratory and field testing, including applications exposed to vehicular traffic.

Schluter-DITRA 150 - 1 roll of 1/8" x 3'3" x 45'9" membrane.

Schluter-DITRA Uncoupling Waterproof Underlayment Membrane - Function:

Ceramic and stone tiles are durable, easy to maintain, and hygienic, representing the ideal surface coverings. However, today's lightweight construction methods can make the installation of hard surface coverings particularly challenging. In order to protect the integrity of the tile assembly, an underlayment that performs multiple functions is required.

Schluter-DITRA is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration, and an anchoring fleece laminated to its underside. Schluter-DITRA is bonded to the substrate using thin-set mortar. The anchoring fleece on the underside of Schluter-DITRA is fully engaged in the mortar to provide a mechanical bond to the substrate. Tile is installed over Schluter-DITRA using the thin-bed method in such a way that the mortar becomes mechanically anchored in the square, cutback cavities of the Schluter-DITRA matting.

Schluter-DITRA Uncoupling Waterproof Underlayment Membrane - Designed specifically for ceramic tile and dimension stone installations, Schluter-DITRA serves as an uncoupling layer, waterproofing membrane, and vapor management layer that accommodates moisture from beneath the tile covering. Further, DITRA performs all these functions while still providing adequate support/load distribution for the tile covering.

Schluter-DITRA Uncoupling Waterproof Underlayment Membrane - Sound Control:

Schluter Systems has never promoted Schluter-DITRA as a sound control system. However, DITRA provides a degree of sound attenuation similar to various thin-set sound control membranes. Schluter-DITRA and ceramic tile were tested* over a 6" (152 mm)-thick concrete slab and the measured IIC rating of this assembly was 10 points greater than the measured IIC rating of the bare slab (IIC bare slab = 28, IIC slab w/DITRA and tile = 38). This level of performance is not sufficient to meet typical code requirements without additional sound control measures. As discussed above, the use of a sound control underlayment in combination with a load-distribution layer such as a mortar bed, lightweight concrete, or gypsum concrete can significantly improve the IIC rating of the assembly. Sound-rated ceilings can improve the IIC rating as well. Please note that this testing was performed prior to the approval of the ASTM E2179 standard test method and used a smaller specimen size (4 ft x 4 ft) than required by existing sound control test method standards.
