How to calculate formwork for a retaining wall?

The construction process cannot function without additional support tools, as well as consumables. This applies especially to wall formwork, without which it is difficult to imagine any concrete wall structure. One-sided formwork is used for building retaining walls, columns, and foundations. Its design features consist of the availability of a modular frame system (buttress): when one-sided concreting is done pressure of concrete is transmitted to the base through the retaining frame. The buttress element facilitates transportation, installation, and operation of one-sided formwork, allowing the accomplishment of work in the shortest time and with less effort.

The difficulty of calculating formwork largely depends on the shape of the concrete form you’re supporting. While a square or rectangular form will be straightforward to calculate and suitable for modular formwork, round or irregular forms may be more challenging and needs to be custom-made.

If we use plastic formworks which can be used several times on the same project or on different projects, this will lower the overall cost. However, the measurements need to be precisely the same each time. Plastic formwork can be reused multiple times, but wooden formwork may not stand up to reuse, especially over long periods.

Formwork is needed to support vertical concrete forms such as walls, columns, pillars, etc. For wall forms, calculate the perimeter of the base and multiply it by the height. Nova Formworks is known for its modular formworks system. Connect with us for your next project!
