Cap Ferrat Building with Dekton® by Cosentino

3,800 m2 of the ultracompact surface Dekton® by Cosentino have been used in the remodelling of the façade of the iconic Cap Ferrat building.
Cap Ferrat is an iconic residential building located on the exclusive Avenida Vieira Souto in Ipanema, Rio de Janeiro. Built in 1976, this iconic feature of the Brazilian neighbourhood of Ipanema has a surface area of 2,000 m2 and is 20 floors high. It includes flats, duplexes, garages and spaces for public use.
Between 2013 and 2016, forty years after it was built, a remodeling project was carried out on the building’s balconies cladding due to the deterioration caused by the galvanic corrosion of the aluminium parts of the railings, which caused cracking of the original granite pieces that sheathed the perimeter beams of the tower’s six balconies.
The architecture studio in charge of the project, Di Filippo Arquitectura, studied the behaviour of various materials and decided that Dekton® brought together all the necessary and indispensable requirements for the rehabilitation work on the façade.
Juan Carlos Di Filippo. Architect: “As we had decided to keep the existing cladding, we had to choose a cladding material with very particular properties: its porosity needed to be as low as possible in order to resist the damage caused by a seafront environment; it needed to weigh as little as possible, but have large dimensions; and it needed to be able to be installed using the system of stainless steel inserts. Last, but not least, it needed to have a low level of solar absorption (characteristic of the area), as well as to suit the chromatic tones of the beach sand, as the Cap Ferrat is located on Ipanema Beach. After analysing several materials, the choice fell on the ultracompact surface Dekton® by Cosentino. It united all the requirements set for the project.”
The great challenge faced by the working team was searching for a new cladding that could be installed over the original and that would weigh no more than 90 kg per square meter. At the same time, due to its proximity to the ocean, the material chosen needed to suit the aesthetics of the outside environment, offering gentle, agreeable colours for its surroundings, as well as offering mechanical properties that could resist the deterioration that this type of area often produces.
Di Filippo Arquitectura chose Dekton® by Cosentino for the façade because it represented 50% of the weight permissible for the material, because it could be made in large-format slabs (3.2 m x 1.44 m) and custom sizes, for the cutting precision of the pieces, for its ideal performance when faced with erosion caused by beach sand and salt residue, and other exceptional qualities such as its high resistance to UV radiation, colour stability and high stain resistance.
The custom cutting of the 12 mm-thick pieces, as well as their number, dimension, and the precise location of the holes, was carried out at the Cosentino factory in Cantoria, Almeria (Spain), for later shipment by boat to Brazil. The holes were made through a novel anchoring technique designed for the project by the company GMM Anchor Systems with the ongoing collaboration of the Cosentino engineering department. Keil pieces provided by Cosentino were used for the anchoring. The rest of the pieces and metal accessories were made by GMM.
The Dekton® colour chosen for the façade cladding was the cream colour Danae for its elegance and chromatic similarity to the colour of the beach sand.
