DURABASE CI The perfect solution from www.Wetdecs.co.uk
THE PROBLEMS
1. Moisture from above
Tiling in itself is not waterproof: junctions to fittings and walls are particularly susceptible to water ingress which can damage the foundation.
2. Moisture from below
In the case of anhydrite screed, residual moisture from the screed can collect under the
installed tiles and damage the adhesive bond. Accordingly, tiles must only be installed
following attainment of a residual moisture content of > 0.5%, or 0.3% in the case of
installations with under floor heating, as measured with the CM device.
3. Foundation stress
Depending on the structural design and the materials used, the foundation can be
subjected to stress which could then be transferred to the tiling and result in cracks
(bridge over cracks up to 0,4 mm). In the case of concrete, for example, creeping and
contraction can lead to deformations after periods lasting as long as 6 months to several years. Cement floors and heated screed can also experience movement after being covered by tiles or slabs. Similarly, chipboard and compressed board deform notably through moisture absorption.
4. Foundation cracks
During restorations of old wooden or tiled floors, cracks in the foundations can occur so
that secure installation of the new tiles is no longer guaranteed.
5. Heated screed
DURABASE CI decoupling mats can safely be laid on any kind of heated screed
foundation without any impairment of the heating performance. The mats should be
adhered with the heating switched off, using a suitable flexible adhesive conforming to
DIN EN 12004 C2. It is also possible for electrical or hot water heating systems to be laid directly on top of CI matting. Heating pipes must be installed in accordance with the
applicable specifications of the manufacturer. Such specifications vary but will commonly involve the pipes being embedded fully in the tile adhesive layer. For heated floors the thermal resistance over the entire area of the ceramic flooring must not exceed 0.15 m² K/W in accordance with DIN 1264 (Underfloor heating systems and components).
THE SOLUTION
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.
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.
INSTALLATION
The foundation must be stable, level and free of loose material. Before installation,
the DURABASE CI mats are cut to the required dimensions. The thin-bed mortar or
fluidised-bed mortar is applied to the foundation by means of a 4 x 4 mm serrated
trowel. The tile adhesive must be matched with the substrate. Best results are
usually achieved with thin-bed mortar, flex mortar or fluidised-bed mortar requiring
hydraulic setting. Recommendations for ideally matched products can be obtained
directly from Dural.

After that, the mats are pressed into place with their carrier fleece facing downwards
and tapped down with a hammer. The thin-bed mortar must achieve a strong
mechanical bond with the carrier fleece under the DURABASE CI mat.The mats
should be laid into the thin-bed mortar before the adhesive dries and any joints taped over. Some protection may need to be provided to prevent damage to the mats.
2.
Once the adhesive for the matting has thoroughly hardened, all recesses should be
filled in so that they are flush over their entire area using tile adhesive. The laying of
tiles can then begin.
Durabase CI and Durabase WP are perfect substitutes for Schluter Ditra and Schluter Kerdi mat for tiling projects.
We stock it in 5, 10, 25m rolls along with all accessories and WP waterproofing membrane.
