Lightweight Void Formers (ABS Raised Void Filling Systems)

ABS Void Formers are single-use, recyclable plastic molds used to create lightweight, elevated concrete slabs up to 300 cm. They replace traditional heavy fill methods with an eco-friendly, fast-installation solution that reduces load, speeds up construction, and provides under-slab voids for utilities. The system supports ramps, partition walls, insulation, and acts as a vapor/radon barrier.

• Lightweight – Minimal logistics – High load capacity • Up to 300 cm fill height – Fast setup – Radon/moisture barrier • MEP ready – LEED-compliant – Compatible with internal/external use
