ABS Void formworks are concrete-shaping structures made of recycled plastic that are only used once. Also known as disposable formworks, void formers, permanent formworks or single-use formworks, they create reinforced concrete raised floors up to 300 cm, offering a lightweight, fast, easy and economical fill solution for any structure. Compared to conventional fill applications, reinforced concrete raised floors constructed with ABS Void Formworks are faster and easier to build, lighter in weight, and more cost-effective.

ABS Void Formworks can be used for any sort of lightweight fill application. Uses include sunken slab fills, landscape fills, amenity floor construction, inverted beam fills, fills between foundation footings, car park ramps, swimming pool decks, elevator/staircase hallway fills, crawlspace construction, LV distribution rooms, rainwater harvesting and flood prevention.

ABS Void Formworks are produced in two different types depending on whether the leg height is ABS Level fixed or ABS Plus adjustable.
