Large-area formwork Top 50

The large-area formwork for all shapes and loads

Large-area formwork Top 50 is a 'construction kit' large-area formwork system that is pre-assembled on a project-specific basis and is designed to accomplish many very diverse types of task. The shape, size, tie-hole pattern and form-facing of the elements can be adapted to suit any requirement.


Executional reliability
resulting from project-specific design 

  • fulfils any architectural requirement, as there are no restrictions on the choice of form-facing and tie-hole pattern
  • permits any pouring rate, as it can easily be dimensioned for any fresh-concrete pressure

Fast, efficient working
thanks to optimised formwork solutions 

  • cuts equipment costs by allowing high numbers of repeat uses
  • cuts labour costs by facilitating short forming-times
  • minimises the craneage requirements because of its large, optimised shifting units

thanks to precision pre-assembly by the Doka Pre-assembly service 

  • perfect joint pattern thanks to the exact element joints
  • time and space savings at the site
  • no finishing-work needed, as the elements fit exactly
  • special solutions for bridge, tunnel and industrial construction

Comprehensive workplace safety
with compatible ladderways and working platforms 

  • safe vertical access with the Ladder system XS
  • workplace safety on all sides with the Platform system Xsafe plus
  • practical accessories – such as panel struts, lifting/repositioning devices etc. – make for safe, easy handling of the formwork



Top 50 in detail

The Doka formwork beams H20 (1) and the steel walings (2) are spaced closer together or further apart, depending upon what loads are expected. The form-facing (3) is freely selectable, to meet widely differing requirements.

Formwork built by Pre-assembly

The individual parts of the Top 50 system can quickly be assembled into site-ready elements by means of easy-to-use connecting devices: this saves on assembly costs. Having the elements pre-assembled ensures top-quality, meaning precision element joints and a first-class joint pattern, even with challenging geometries. For high numbers of repeat uses, fielding Large-area formwork Top 50 pays off even more.

Free choice of form facing and form-tie pattern

With the Top 50 system, key architectural specifications can be fulfilled.


Fair-faced concrete

Because it can be used with any form facing and adapts to any shape of structure, Large-area formwork Top 50 is particularly suitable for forming concrete that has to meet stringent specifications regarding its surface finish (i.e. fair-faced concrete).
