The refurbishment of the Canary Islands Government Presidency headquarters has been completed

La impermeabilización es una actuación clave en cualquier edificación. A nivel estructural, la protege de los efectos de la lluvia y de la humedad. Y optimiza las condiciones de habitabilidad y eficiencia energética. Una mejora que Desarrolla Obras y Servicios acaba de completar en la sede de la Presidencia del Gobierno de Canarias en Las Palmas. Un proyecto que ha permitido además reforzar la estructura del icónico edificio al corregir deformaciones y fisuras detectadas.

The building that houses the Presidency of the Canary Islands Government, located in a central square of Las Palmas, had numerous damp issues in the past. Therefore, it was essential to carry out a rehabilitation and a waterproofing of the facades and the roof of the building, actions included in the project by the architect Alfredo Martín Montesdeoca.In the collective imagination, the Canary Islands are a subtropical paradise where it never rains and the temperature is always between 20 and 25 degrees Celsius. And the truth is, it is indeed a paradisiacal place, but it's also true that, although it's not London, the islands do experience rain with some frequency. A reality that, coupled with the humidity associated with the island nature of the territory, ultimately causes damage to buildings if they are not properly protected.That is, precisely, what had happened to the headquarters of the Presidency of the Canary Islands Government.

The most visible aspect of the problem

On one hand, prior to the execution of this project, there were issues with moisture infiltration due to the lack of waterproofing on the upper side of the decorative beams. Consequently, rainwater would seep in from the outside through absorption or via cracks and fissures.On the other hand, interstitial condensation dampness had been detected. These occur in air chambers or within materials where thermal bridges of the external enclosures are found.These anomalies, in addition to damaging the structural elements, had an impact on the visual aspect. For instance, through the corrosion and rusting of steel bars, or the emergence of cracks and deformations. But also due to the presence of moisture on the facades, on the roof and even inside the building, in the dome of the entrance hall.In light of all this, the Canary Islands Government decided to launch a tender process to promote the rehabilitation and waterproofing of the building.A process in which Desarrolla Obras y Servicios emerged victorious. Our teams have proceeded to waterproof the facades by applying water-repellent treatments to the tiles and sealing the expansion and cladding joints. The entire roof has also been waterproofed.Furthermore, an antenna whose installation contributed to water infiltration has been removed. All these measures have been key in addressing the dampness and protecting the building against the effects of rain or condensation.

Rehabilitation: Restoring the Deteriorated

Furthermore, restoration actions have been initiated. Thus, damaged or loose tiles were removed and replaced. The skylights' waterproofing was also addressed by renewing their seals, and the waffle slab coffers in the basement were repaired due to the oxidation of the reinforcements.In keeping with this approach, the facades were cleaned and finishes were meticulously cared for, using exterior acrylic resin paints to ensure that the painted surfaces do not absorb moisture or germs of any kind.The aim of all these efforts has been to ensure the waterproofing and reinforcement of the building's structure. Concurrently, enhancing the livability and comfort within the headquarters of the Canary Islands Presidency.Discover our work at www.desarrolla.esVisit us at our office in Las Palmas de Gran Canaria.
