Cardboard void formers for foundations

It looked far too ambitious for many people. More than once I got asked if I was serious.

Armadillo™ 500R/C Foundation – Pods Layout

It was a difficult but an exciting challenge.
It was 2012. I wanted to create an alternative to materials made from petrochemicals to be used as void formers. That’s when I began looking at for the development of a cardboard pod.
Carton formers were already used in the construction industry (to form the void) space between the bottom of grade beams and slabs over expansive soils [1] to form pockets [2] and to construct circular columns) but I needed something different. I wanted my cardboard to be modelled in a complex shape, to be suitable for use in wet weather, to provide enough strength to resist under the pressure of wet concrete and to be safe for a builder to walk on.
It looked far too ambitious for many people. More than once I got asked if I was serious.
We worked relentless for three years and eventually achieved a wonderful product able to satisfy all our needs.
We have been the only (so far) and first to use a pulped moulded cardboard for this application: The Armadillo 500R/C at CTV news

Unfortunately, the limits in the production efficiency forced us to suspend the use of this amazing material for the time being. Industrial processes are evolving so in the future I hope that we or someone else will be able to use this material on a larger scale.
