Schluter - 3' 3" x 33' - DITRA-DRAIN drainage membrane

Schluter-DITRA-DRAIN is a passive capillary drainage and uncoupling mat for outdoor use on slopes of at least 1.5 cm per meter. Schluter-DITRA-DRAIN 4 consists of a polyethylene mat with a structure of approximately 4 mm high truncated cone-shaped studs, to which a permeable polypropylene nonwoven is bonded, and approximately 2 mm high truncated pyramid-shaped studs, laid upside down. These studs create dovetails on the underside, which serve to anchor the adhesive. This must be placed on the substrate using a 6 x 6 mm notched trowel; the Schluter-DITRA-DRAIN 4 mat will be embedded in this mortar. The white non-woven fabric on top of the mat is used to receive the adhesive mortar intended for fixing the covering. This non-woven fabric is permeable to water and vapour, and allows the adhesive mortar to dry quickly, while preventing water from rising in the covering (passive capillary action). Due to their close spacing, the truncated cone-shaped studs can withstand pressures of up to 50 t/m², the dovetails also ensuring very good adhesion to the substrate. Schluter-DITRA-DRAIN 4 is suitable for uncoupled indoor installations for installing large-format tiles (larger than 60 x 60 cm).

• The scattered structure of Schluter-DITRA-DRAIN allows for in-plane movement between the tile and the substrate. This effectively neutralizes the stress between the two, eliminating a major cause of breakage and delamination.
• Schluter-DITRA-DRAIN allows excess rainwater and runoff to escape to the tile below, preventing mold buildup.
