VoidX™ Cardboard Sheets

Danterr’s VoidX™ Cardboard Sheets are lightweight, durable cardboard void formers designed to create space between reactive soil and concrete foundations. Made from recyclable honeycomb cardboard, they help protect concrete structures from upward pressure caused by soil expansion.

Available in 2400mm x 1200mm sheets, with thicknesses ranging from 25mm to 150mm, these concrete void formers support the weight of wet concrete during pouring before gradually breaking down to create a void for soil expansion. Their strong yet lightweight construction makes them easy to handle and install, improving efficiency on site.
