Prefaxis is your partner for precast products, from basement to roof points. Your needs and concerns are our priority!

In addition to twin walls, we also offer ceramic precast walls and beams. With this, we respond to the demand for more efficient construction methods and to the growing trend toward prefabrication in construction, ranging from utility buildings and apartments to combined complex projects. This is always commissioned by contractors and architects.


  • The Ploegsteert Group has more than 100 years of experience in the building industry.
  • All our products carry the CE and/or BENOR mark. Our ceramic precast walls have the ATG mark.
  • We continuously invest in the latest production technologies.
  • We are only too happy to put our expertise in stability and other construction advice, site start-up and product selection at the disposal of our customers.
  • The integration of the various steps in the production chain within the Ploegsteert Group naturally contributes to the greater reliability of our products and services.



  • Prefaxis goes for 100% worry-free building: our technical commercial advisors are your point of contact for all our products.
  • They provide a prefab proposal worked out down to the last detail, assist you with the approval of the drawings and, if required, help with the start-up of the site so that you can look back on a smooth collaboration.


  • At Prefaxis, innovation is in the DNA: Prefaxis is the only company that uses polyurethane to glue prefab walls, thereby significantly reducing the lead time.
  • Prefaxis is also distinguished by the almost infinite possibilities of applying surface structures in industrial concrete.
  • Our engineering office has fully embraced BIM, making most complex projects no problem for us.
