Concrete is the most used material in building structures for buildings.

It has excellent fire resistance and low maintenance costs. It offers the biggest weight, which can be an advantage when trying to increase the structural stability as well as greater protection against chemical attacks. It is excellent against tensile or compressive pressure, and has high durability. In fact, it presents an optimal cost in relation to the useful life it offers.

In return, its elements are heavier than other similar wood or steel at equal strength.

The material used is HLE-25/B/10/IIa concrete with oblong straps.
