Telescopic formwork

Ground-breaking innovation in wallforms

In recent years, the requirements for reinforced concrete walls have been increasing steadily. Self-compacting concrete, symmetrical ties and joint structures, class SB 4 fair-faced concrete or "Dyckerhoff white" (white Portland cement) are just a few keywords found in connection with these tough demands. The demands placed on the concrete are largely responsible for the standards that have to be applied to the formwork. PRIMAX telescopic formwork is the first wall formwork to be specially adapted to deal with these modern requirements.

PRIMAX fulfils not only the need for flawless concrete surfaces and concrete load capacity, but also that of economy and provides unique variable height adjustment(!).

By means of a telescopic principle designed specifically for use on the construction site, it is possible to extend the grid, adjust it exactly to the respective wall height and apply a formwork lining piece by means of a quick-release fastener.

The following panel heights and widths are available:

New development

The PRIMAX Vari clamp allows infinitely adjustable bolt positioning in a vertical direction.

Essential product benefits at a glance:

  • Height adjustable using telescopic functionality
  • High load-bearing capacity (80 kN/m² or 100 kN/m² depending on anchor position)
  • Low deflection (in compliance with DIN 18202 line 7)*
  • Low anchor ratio (ideally 0.5 anchors/m² wall area)*
  • Free choice of formwork lining – change by means of quick-release fastener
  • Formwork lining is attached from the rear – no impressions of the screws in the concrete

* fulfils requirements for fair-faced concrete
