FORMAVOID 100
F1001

Formavoid is a 100mm deep plastic void former that encourages fill material into an extremely strong series of columns and arches, leaving 60% open void space beneath the arches for source control water management & storage. When filled with aggregates, ranging in particle sizes from 1mm – 40mm, Formavoid combines with the aggregate to create a granular base with enhanced stability and increased water storage capacity.
