We are proud to participate in a project that doesn’t just build houses, but sets new standards for energy efficiency, safety, and speed. This is about the application of the modern Sismo system—a permanent formwork technology that is redefining construction benchmarks.

What is Sismo?
It’s like a construction set from the future: two panels of high-density expanded polystyrene (EPS), connected by steel ties. Concrete is poured into the resulting cavity, forming a monolithic, ultra-strong, and well-insulated wall.

Why is this a breakthrough for Spain?

1. Passivhaus-Level Energy Efficiency
   Hot summers and cool winters in central regions are no longer a problem. Sismo provides exceptional thermal insulation, significantly reducing air conditioning costs.
2. Seismic Resistance – Hinted in the Name
   The rigid concrete framework is ideal for regions with high seismic activity, such as Granada, Alicante, or Murcia. Safety becomes the foundation of the home.
3. Speed – Like Building with LEGO
   Wall assembly speeds up the construction of the house structure by 30–50% compared to traditional brickwork (ladrillo). Construction timelines no longer need to intimidate clients.
4. More Space – Thinner Walls
   The structure is thinner than multi-layer counterparts while maintaining superior insulating properties. The result is extra usable floor area without compromising comfort.

The Numbers Speak for Themselves
The project is being implemented in 2.5 years with impressive financial efficiency:

• ROE ~25%
• ROI ~19.5%

This is more than just construction—it’s an investment in technologies that pay off through increased demand, faster project delivery, and long-term savings for residents.

Sismo is the answer to modern challenges: climate, seismic risks, urbanization, and the demand for quality housing. We build faster, warmer, and safer. And this is just the beginning.
