Schlüter®-DITRA-DRAIN as a bonded drainage and bonded uncoupling membrane over a Schlüter®-KERDI bonded waterproofing assembly

Structural assemblies with bonded drainage over bonded waterproofing assemblies

The sloped support structure is protected against the permeation of water with a Schlüter®-KERDI bonded waterproofing assembly, which is produced with a dry set mortar in the thin-bed method.

The passive capillary bonded drainage membrane Schlüter®-DITRA-DRAIN is installed in the thin-bed mortar between the waterproofing layer and the tile covering. This results in the broad ventilation of the top covering, which in turn promotes the quick and even drying/curing of the thin-bed mortar. The uncoupling function of Schlüter®-DITRA-DRAIN neutralisies any stresses occurring in the substrate.

  1. Cantilevered concrete slab with sloped screed (1a)

    The construction has to be sufficiently sloped (1.5 - 2%) to allow for proper drainage.

  2. Schlüter®-BARA-RTKE

    Edge profile with drip lip and attachment mechanism for the Schlüter®-BARIN gutter system.

  3. Schlüter®-KERDI

  4. Schlüter®-KERDI-KEBA

    Polyethylene sealing tape with fleece laminated on both sides for anchoring in the sealing adhesive Schlüter®-KERDI-COLL to  create waterproof wall connections, seams, and transitions

  1. Schlüter®-DITRA-DRAIN

    Polyethylene drainage mat installed using the thin-bed method, for bonded drainage, ventilation and uncoupling. It is important to ensure a drainage channel.

  2. Schlüter®-DILEX-EKE
