DURABASE CI ++ matting used in conjunction with tiles serves to decouple the tiles and bridge any cracks. It also allows water vapour pressure to be compensated for if there is residual moisture. DURABASE CI ++ decouples the flooring from the foundations. Any small cracks can also be bridged so they do not affect the tiling. This makes it ideal for renovation work.

DURABASE CI++ mats are made of yellow polythene with a grid of texturing nodules and a supporting polypropylene fleece layer on the back. This combination means the matting is resistant to most chemicals (e.g. salts, acids, alkalis, solvents and oils, although when the locations are seriously at risk from chemicals, it is recommended that a professional assessment be made for the use of the mats).


For specific peculiarities depending on the situations, it is recommended that a professional assessment be made for the use of the mats with regard to the expected concentrations, temperatures and durations of exposure.

Decoupled flooring layers can sound different when walking on them with hard soles or heels. According to DIN-EN 12004C2, the thin-bed mortar being used for the flooring material must be suitable for the required usage. Outdoors, specific attention should also be paid to whether the material is resistant to heat and frost. Furthermore, it may be necessary to use special protection when laying flooring outdoors.

It is common practice to divide the foundation under the flooring into areas with expansion joints. The expansion joints in the tiling need to match those already existing. We recommend using junction profiles from the DURAFLEX range for this. Expansion joints should also be laid in decoupled floors as area perimeters, edging and junctions. This should also be planned and carried out in keeping with common practice. The joints in the CI decoupling layer need to match those in the foundations, too. In any areas subject to large quantities of moisture, the joints will need to be waterproofed using loops of WP or WPF sealing tape.

On floating cement screed, expansion joints are required at all door thresholds, in areas in excess of 60 m² in size or where a side of the area exceeds 8 m in length, wherever there is serious cracking in the floor surface, above existing building expansion joints and so on. For calcium sulphate screed, the stipulations of the respective screed manufacturer should be observed. Otherwise the relevant data sheets provided by the "tiling and natural stone" trade association should apply.

When the mats have just been laid, it is recommended that boards be laid over them if they need to be walked on. This should prevent damage.
