2.07 MODULAR SCREED SYSTEM
---------------------------------------------------------------------------------------------------------------------------------
Schluter
®
-BEKOTEC is a modular screed system that produces permanent flooring assemblies
that are free from internal stresses. This allows for the installation of continuous screed surfaces
without any saw cuts or control joints. Ceramic and stone tile is set over the screed using the
thin-set method, in conjunction with the Schluter
®
-DITRA uncoupling membrane, while surface
coverings not sensitive to cracking, such as parquet or carpet, can be installed directly over the
screed as soon as the residual moisture has reached an appropriate level. The system is self-
supporting, making it possible to place additional layers of heat and/or sound insulation to obtain
the desired effect. The system is also designed to hold hydronic radiant heating tubes without
fasteners.

2.08 UNCOUPLING MEMBRANE
---------------------------------------------------------------------------------------------------------------------------------
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 specifically designed to allow the installation of ceramic and stone tile over
any even and load-bearing substrate. The integration of DITRA’s uncoupling, waterproofing, load-
distribution, and vapor management functions makes consistent results viable.
