After carrying out a series of tests, MAPETHERM SYSTEM was chosen for the external thermal insulation of the buildings. Going into detail, MAPETHERM AR1 one-component, cementitious adhesive and mortar, which has high bonding strength and a low level of viscosity that ensures excellent workability, was used to bond and smooth the insulating panels for the external thermal insulation systems. Thanks to its high level of thixotropy, MAPETHERM AR1 may be applied on vertical surfaces without sagging and without letting even large-size insulating panels slip.
The surfaces of the walls were finished off with the SILANCOLOR cycle, which consists of an undercoat of siloxane coloured SILANCOLOR BASE COAT, with good defect-covering and filling properties, SILANCOLOR TONACHINO siloxane plaster and, lastly, water-repellent, transpirant siloxane SILANCOLOR PAINT PLUS, which has a good level of resistance to mould and algae.
MAPELASTIC, an elastic two-component cementitious mortar for waterproofing balconies, terraces, bathrooms and swimming pools, was used for the waterproofing of the balconies.
For roof waterproofing, in order to combine the design requirement of fire resistance with aesthetic appeal, Mapei supplied PURTOP FR, a two-component, solvent-free, hybrid polyurea membrane to be sprayed using a high-pressure bi-mixer pump. With the application of PURTOP FR it was possible to guarantee a waterproof and perfectly fire-resistant system.
AQUAFLEX ROOF PREMIUM, a ready-to-use water-based polyurethane membrane with excellent waterproofing, elasticity and fire resistance properties, was applied onto the PURTOP FR layer to give the covering the desired aesthetic result without losing its fire-resistance. It was thus possible to satisfy all the requests related to the project.
The Mapei solutions worked exceptionally well and the works director chose Mapei as sole supplier for the next stages of the project.
