The external façades, the inside of the swimming pools and the floors and walls in the reception area, changing rooms and bathrooms were all dressed with Alta slate, a special clay-based porcelain tile which can be found in some specific zones of Norway. This type of stone requires the use of specific, durable adhesives and grouts.
The products chosen for this particular work were CONPLAN ECO R rapid self-levelling mortar to form substrates from 3 to 20 mm thick, CONFIX spray-applied mortar to repair the concrete and MAPEPOXY L epoxy adhesive to repair the cracks. These products are all made and sold in Norway by Mapei AS.
The concrete surfaces were restored with MAPEGROUT T40 thixotropic mortar. Where required, surfaces were waterproofed with MAPELASTIC two-component cementitious mortar, which is particularly suitable for creating highly flexible, protective waterproof coatings on structures subject to cracking.
To install the slabs of ardesia, Mapei Technical Services recommended ULTRALITE S1 one-component, high performance adhesive, while ULTRALITE S2 lightweight cementitious adhesive was the preferred choice for the large format slabs.
The product chosen to fill the grout lines was KERACOLOR GG high-performance, polymer-modified cementitious mortar for grout lines from 4 to 15 mm wide. The expansion joints were sealed with MAPESIL LM and MAPESIL AC.
