Cellform HX System

Cellform HX combines the benefits of Cellcore HX B with an economical and simple to install permanent formwork system. Each Cellform HX panel is supplied to the required beam width and depth, allowing them to be quickly installed with the range of accessories available.


  • Combined heave protection and permanent formwork
  • Manufactured to suit ground beam dimensions
  • Range of accessories available including connectors, corners and form braces and staple clips
  • Material scheduling service available

The principle of Cellform HX is that the hinged side panels are supported off the reinforcement cage by concrete spacers, which then allows the excavation to be backfilled. The backfill then supports the formwork against the concrete pressure whilst the beam is cast and thereby avoids the need for fixing and striking traditional formwork.


The Cellform HX range is designed for use as a combined ground heave protection and permanent formwork system for the construction of ground beams.
