Machine foundations

Durability and fatigue strength

There are a wide variety of machines used in the industrial sector (compressors, turbines, rotating machines, centrifugal pumps, etc). Most of them require a foundation, which is generally made of reinforced concrete. The foundation is submitted to dynamic loads, and in some cases to temperature cycles or impacts. These effects may crack it, generating a loss of stiffness that affects to the performance of the machine and that may even damage it at short-term. The use of UHPC instead of ordinary concrete for these foundations has several benefits:


  • UHPC reaches almost half of its compressive strength after 24 h, so the machine can be installed and come into operation after only few hours.
  • The high bonding strength of the UHPC matrix to the steel reinforcement and to the steel fibers reduces the possibility of cracking. In case that they appear, UHPC provides a significant post-cracking mechanical capacity. This provides an excellent fatigue strength to the UHPC option.
  • The depth of the foundation can be lower than with ordinary concrete, reducing the amount of material consumed and gaining space that is available for other uses.
  • UHPC has an exceptional resistance to high temperatures, performing better than other options with ordinary concrete. Besides, the corrosion strength is significantly higher than for steel or ordinary concretes.

UHPC Projects


RDC can evaluate the affordability of using UHPC in an specific Project, conduct an optimized design and deliver the tailored Formex® premix to carry out the in-situ works.





UHPC (Ultra-High Performance Concrete) is an extremely compact and ductile cementitious composite. Its properties make it perfect for applications where durability or maintenance play a significant role, where a lightweight structure is particularly relevant, or where the slenderness or thickness of piece is is important.



RDC works closely with the client to evaluate the technical, economical and environmental viability of replacing its current solution by UHPC. A tailored premix of Formex® is proposed to maximize the competitiveness of the new element.
