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.
