Given the crisis in which our country is mired, todos hemos sido testigos del great impact they are having small solidarity actions of businesses and citizens. In this line, a group of Spanish SMEs based on the initiative of Alberto Alarcón, CEO de la company Holedeck, we wanted to combine our work and effort and launch a crowdfunding project with which to support the work of health professionals in Spain.

Our goal is to provide health centers and hospitals 50.000 masks to help protect professionals against COVID-19. Masks are already manufacturing and Tuesday 31 March we will have the first 3.000 units.

Our masks are being created with local media to ensure self-sufficiency and not depend on import of the material. Es un ASEM112 supported project is the Agency for Safety and Emergency Madrid 112, which it has already closed its cooperation to facilitate the assembly and distribution of masks.

This project is already underway, It goes against the health emergency. Y arrancarlo ha sido posible gracias a la donation made by relatives of Eladio Jimenez Alarcon, a victim of coronavirus. His nephews have decided to donate 6.000 euros to support the fight against this pandemic that is causing thousands of deaths worldwide.

But we need more. We need your help.

How I can make my donation?

  • Puedes hacer tu donación a través de este account number:

Headline: Juan Sebastián Alarcón
Account number: ES8901280073640100046957

It is important that the concept always indicated the word donation: "Donation mask COVID-19".

  • También puedes hacer tu donación a través de BIZUM to the phone 645 035 760 Juan Sebastián Alarcón.
  • Otra opción para hacer la donación es la DRIP platform microfunding.

Each sum gesture, why only we stop this virus States.

Funds and Budget

In a first phase, the aim is to produce 20.000 units and reach 50.000 in a second phase.

In this document you can see the itemized budget of the first phase.

As of 27 March 2020, we have raised 5.895,36 euros that, added to the 6.000 euros donated by the nephews of Eladio Alarcon, for a total of 11.895,36 euros.

How useful are these masks?
Yes, they are useful, They have been tested and approved by medical personnel.

Are they coming to hospitals?
Yes, We are directly distributing masks and are in contact with hospitals and with the Community of Madrid.

They Are Approved?
They are in the process of approval, but approval would delay the process. This is war, masks are needed and, homologated or not. Health that are using the version made with 3D printer are very satisfied with them.


From 2020, the energy consumption of buildings will be nearly zero (NZEB). But do we know how to achieve it?

Holedeck and Uponor have developed HOLEDECK ACTIVE BASIC an innovative thermally-activated concrete slab, result of the research project carried out with the participation of ¨Holedeck¨, the ¨Spanish Institute of Cement and its applications¨ and ¨Eduardo Torroja Institute of Building Sciences¨.

This Holedeck lightweight slab is already the most efficient solution of the market in relation to material consumption, minimizing the environmental impact. In addition, the use of perforations for the passage of facilities currently reduces the height required on the ground of non-residential building and promoting the possibility of having an additional plant for every x plants built. The design of the HOLEDECK ACTIVE BASIC slab allows integrating systems and elements specifically designed for standard modular ceilings, as well as geometries and adapt to conventional modulations.

In addition, this slab can thermally activate by the integrating system Uponor TABS (Thermal Active Building System). By a framework of integrated circuits into the slab, water runs into the structure previously heated or cooled by any source of renewable energy (geothermal, aerothermal, solar…) to modify the temperature of the concrete slabs and use its inertia. This way, the slabs contribute to cooling and heating the environment in a healthy way, silent, without air drafts and according to the needs and comfort of air conditioning required at all times.

HOLEDECK ACTIVE BASIC contributes to the achievements of buildings NZEB and European targets of Circular economy. Running costs are reduced by more than 30% regarding existing buildings, and energy consumption by up to 60%.

Structures that must resist seismic loads have to be designed and conceived under this premise from the very beginning of the process. This fact is so relevant that can (and should) affect in a general way the selection of the structural system.

In general, every seismic-resistant building consists of three types of elements:

Since installations have become a fundamental aspect of projects, with a significant presence in the overall budget, and volume of the building, designers have tried to integrate them as much as possible with the building, making them coincide with other architectural elements such as structure and envelope.

Welcome. From HOLEDECK we are convinced of the structure’s relevance in sustainability. We believe that future structures should have the smallest direct and indirect impact on the carbon footprint, should be flexible, and allow for versatility which translates in greater possibilities of configuration and uses, which can contribute actively and/or passively in the construction of nearly zero-energy buildings (nZEB). That is our commitment.
