VoidForm “Sacrificial Formwork”

VoidForm offers an extensive list of products that are all focused on “forming voids” for concrete walls, slabs, and piers, as well as below-grade utility isolation. VoidForm’s products address a simple but enduring problem: In areas with expansive soils, void forms provide temporary support during concrete placement. Once the concrete is self supporting, these forms provide a cavity where soil can expand, preventing the transfer of uplift pressures into the structural slab or beam above. voidform.com
