The SMK system is a single-sided formwork solution with a truss structure consisting of MK Walers. A distinctive aspect of this system is that it is flexible enough to consider access solutions on site, particularly important for tunnel projects. This system has a maximum height restriction of 10.5 m. There are several truss types depending on the required formwork height. There are different SMK frame sizes to accommodate differing wall heights:


SMK Frame no. Max. wall height
3 3m
3.4 3.4m
5.4 5.4m
8.7 8.7m
10.5 10.5m

System Advantages


  • Single-sided formwork systems are compatible with any type of ULMA vertical formwork either modular (i.e. ORMA) or beam formwork (i.e. Enkoform VMK).
  • Quick and easy fixing to panels.
  • Once assembled, each set of panels and trusses can be lifted and moved to the required pouring locations.
  • For safety, when working at high elevations, working platforms can be incorporated into these systems.

Applications and Solutions


  • Compatible with ORMA
  • Can be anchored to the concrete floor
