Clayform Honeycomb Cardboard Void Former (includes bag)

The Cardboard Void Former (includes bag) is a moisture-sensitive, honeycomb-structured sheet designed to support wet concrete during pouring and then break down over time to accommodate ground movement. Its protective bag ensures the product remains intact during transport and handling, making it a reliable solution for construction on reactive or expansive soils.

Features + Benefits:

Engineered Void Creation: Decomposes after curing to form a void beneath the slab, reducing stress from soil movement.
Honeycomb Structure: Offers strong load-bearing support and efficient load distribution during concrete pouring.
Bagged for Moisture Protection: Prevents premature degradation before installation on site.
Ideal for Reactive Soils: Helps minimise cracking and structural issues caused by soil expansion and contraction.
Product Uses: Suitable for slab-on-ground construction in residential, commercial, and civil projects where soil movement is a concern.
Pack Size: 2400mm x 1200mm x 50mm and 20mm (includes moisture-protective bag).
