For the Mapei technicians and engineers, it is vitally important they work alongside designers and provide their support during both the initial delicate phase of drawing up the building specifications, and then again when work is being carried out on site.

A concrete example of this collaboration was the relationship they built up with the architect Erich Milanese, owner of the Milanese Architects Office design studio, who worked on the design and construction of a residential villa in Santa Lucia di Piave, not far from Treviso (Northern Italy).

One of the aims of the design was to keep the ridges of the roof perfectly in line with the flow of the outside walls – made up of a mix of external insulation and precast blocks with cut-outs – so that the entire roof/wall assembly would form a kind of “uniform box”.

One of the first decisions was to reject the idea of waterproofing the structure with a polyurea membrane because, with this type of solution, that “natural consistency” the designers were striving to achieve would not have been guaranteed.

Following a thorough analysis of the structure and after taking on board the precise indications of the designer, Mapei supplied the most appropriate and best performing product systems for the various work cycles as and when they were required.


The roof of the villa is made up of ribbed metal sheets. Once the concrete cap had been completed, it was waterproofed with a coat of self-adhesive bituminous membrane, then a layer of insulating panels was placed thereupon before casting a final pour of concrete which was 20 cm thick.


For this type of substrate, application of the Mapei product system began with sanding down the existing concrete substrate and then applying a coat of PRIMER 3296 diluted 1:1 with water. For the actual waterproofing layer, the product chosen was MAPELASTIC SMART two-component, high-flexibility cementitious mortar. To improve its elongation and crack-bridging properties, MAPETEX SEL
macro-holed, non-woven polypropylene fabric, specifically designed to reinforce waterproofing membranes, was embedded in the MAPELASTIC SMART layer.

Once the surfaces of the roof had been treated as above, they were painted and protected with ELASTOCOLOR WATERPROOF flexible acrylic resin-based paint in water dispersion.

Particular care was taken around the fillet joints between the steel guttering and the roof and between the dormer windows and the vents on the roof.

The best results were obtained by sanding down all the metal elements and fittings and applying a coat of EPORIP two-component, solvent-free epoxy adhesive. Then, after broadcasting the surface with QUARTZ 1.2 sand, the waterproofing cycle for the roof was applied as described above.



The external insulation for the walls was made up of 14 cm thick MAPETHERM EPS expanded polystyrene insulating panels and MAPETHERM AR1 GG one-component, coarse-textured cementitious mortar.

The surfaces were skimmed over with MAPETHERM AR1 GG, reinforced with MAPENET 150 alkali-resistant, glass fibre mesh embedded in the mortar.

A further skim coat was provided by applying MAPETHERM FLEX RP cement-free, fibre-reinforced, elastic, lightweight skimming paste and base coat.

To improve its resistance to the stresses caused by temperature variations and small movements, ELASTOCOLOR NET alkali-resistant, glass fibre mesh was embedded in the skim coat.

Once this cycle had been completed, the surfaces were finished off by applying a coat of ELASTOCOLOR WATERPROOF.



The footpaths outside the villa and the external areas of the building were waterproofed with MAPELASTIC TURBO two-component, rapid-drying, elastic cementitious mortar, reinforced with      MAPENET 150 glass fibre mesh embedded in the mortar.

MAPEBAND SA alkali-resistant, self-adhesive, butyl tape with non-woven fabric backing was used to protect all the fillet joints.

The 30x60 cm ceramic floor tiles for the loggia and internal areas were installed with white KERAFLEX MAXI S1 high-performance, deformable, cementitious adhesive with extended open time and no vertical slip, excellent workability and Low Dust technology, particularly recommended for installing large-size porcelain tiles and natural stone slabs.

The joints were grouted with ULTRACOLOR PLUS high-performance, anti-efflorescence, quick-setting and drying polymer-modified mortar with water-repellent DropEffect® and mould-resistant BioBlock® technology.

And lastly, MAPESIL AC pure, mould-resistant acetic silicone sealant with BioBlock®technology was used to seal the expansion joints.
