The DURABASE CI mat has an installation height of approximately 3.0 mm. The mat is made of yellow polyethylene. The indented structure and laminated grid achieve a strong bond to thin-bed mortars. The material is elastic, rot proof and resistant to aggressive substances and liquids such as alkalis, solvents and oils. It is also highly impervious to water-vapor diffusion. DURABASE CI bridges cracks, decouples floor coverings from their substrates, and is suitable for producing seals bonded with floor tiles.
PRODUCT CHARACTERISTICS
DURABASE CI is especially suitable for installing tiles on difficult substrates.
Sealing in outdoor situations
DURABASE CI in conjunction with tiled flooring can, for example, prevent penetration of balconies or patios by seepage of water used in the construction process.
Sealing in extremely wet areas
Even in areas heavily exposed to moisture, such as changing rooms and swimming pool halls, DURABASE CI is suitable as a bonded sealing membrane for tiling.
Crack bridging
The crack bridging properties of the mat make it extremely suitable for installation as part of restoration measures. For example, this mat permits installation of tiles on top old and damaged coverings (“tiling on tiling”). However, major variations in the heights of the substrates cannot be handled. In this case it is recommended that the screed be properly plugged. DURABASE CI is particularly suitable for laying tiles on difficult foundations.
Installation of tiles on wooden foundations
DURABASE CI decouples coverings from their foundation, thus permitting installation of tiles on foundations which experience linear expansion and contraction in response to changes in temperature and humidity. The DURABASE CI mat can also be used to install tiles on chipboard or wooden floorboards following appropriate preparation.
Installation of tiles on poured asphalt
DURABASE CI makes it possible to install tiling resistant to long-term damage even on problematic substrates such as poured asphalt and similar bituminous load-bearing compounds.
Installation on fresh foundations
DURABASE CI allows for reverse compensation of vapour pressure, which allows for installation of tiles onto foundations which are still wet (green). This is especially practical on foundations comprising anhydrite floating screed. DURABASE CI mats make it possible to install tiles on anhydrite screed that have achieved a residual moisture content of 2%. Usually, this eliminates the need for elaborate pre-treatment and special adhesives.
