Schluter BEKOTEC-DRAIN-EN23FD Studded System Panel

Schlüter-BEKOTEC-DRAIN is a reliable covering assembly system for crack-free and functionally safe exterior screeds with ceramic or natural stone coverings.

The system is based on the specially structured studded foil panel Schlüter-BEKOTEC-EN 23 FD with evenly spaced openings and interconnected drainage channels, which, depending on the construction, are either installed over a sloped waterproofing layer or over the area drainage membrane Schlüter-TROBA-PLUS. The geometry of the studded panel Schlüter-BEKOTEC-EN 23 FD results in a minimum screed thickness of 31 mm between the studs and 8 mm above them. The curing stresses that occur in the screed due to shrinkage are absorbed by the studded pattern, thus controlling deformations such as curling. Tensions resulting from deformations can therefore not affect the entire area. It is, therefore, unnecessary to install movement joints or control joints in the screed.
As soon as the cement screed is ready to support weight, the bonded drainage and uncoupling mat Schlüter-DITRA-DRAIN can be installed. The ceramic or natural stone tiles are then installed directly over this layer.

This also applies to large format tiles (without format restrictions) made of ceramic material or natural stone. Movement joints in the covering layer are created using Schlüter-DILEX according to industry standards. Ceramic tiles or natural stone tiles may also be installed directly in the mortar bed. For this purpose, the installation screed is installed to a height of at least 8 mm over the studs of the studded panel Schlüter- BEKOTEC-EN 23 FD, and the ceramic or natural stone tiles are set directly into the fresh mortar with a slurry coat. In this case, Schlüter-DITRA-DRAIN is not needed.
