The chambers are designed in high-specification, high-resistance concrete, which allows maintaining high pressures within, achieving an airtight seal with the aid of imported doors and special seals in passages for ducts and energies.

The challenge in this job was to achieve a monolithic casting to be able to comply with the specifications required by the dynamometers for optimal performance. This was achieves through special arch centering, which does not use ties to avoid pressure losses and later cracking.

The concrete was redesigned in Mexico, through one of the most important concrete companies in the country. Its specification is of German origin for this particular project, capable of resisting pressures of 300 bar/cm2, with special additives to self-compact and casting retardant.
