The home of FORMAVOID
Next Generation Drainage
We believe in more than sustainable drainage - we believe in better drainage.
This is a mission to be more than sustainable and improve the way we manage stormwater. The devastating effects of flooding remain a constant threat, and traditional sustainable drainage systems are not enough. We have to adopt better drainage to implement improvements and reverse the effect.
Welcome to the next generation of drainage and stormwater management at source.
WHAT?
A simple way of enhancing traditional construction methods to create void space for managing rainwater at source.
The Formavoid® module is shaped to encourage aggregates into a series of columns & arches. Load is spread through the fill material to the columns, creating an extremely strong & robust product. The space beneath the arches remains open, creating a shallow void space beneath the surface which can be utilised for stormwater attenuation and management.
WHERE?
Subbase attenuation in the built environment | Sports field drainage | Podium deck & roof drainage
WHY?
Reduce construction depth | Increase void/storage volume | Reduce carbon footprint | Reduce construction costs | No underground tanks
Product Features
