Disposable Formwork Systems for Lightweight Filling

GOOPLAST | Adjustable-Height Disposable Formwork & Void Former System (5–300 cm)

An economical fill solution designed to raise finished floor levels above existing slabs or structural bases while minimizing additional dead load and material consumption. The Gooplast disposable formwork system is composed of single-use recycled plastic modules that function as void formers during concrete casting. Once installed and poured, the elements remain permanently within the slab, creating reinforced concrete floors with integrated void spaces.

By replacing traditional solid backfilling, the system reduces concrete volume, lowers structural weight, and accelerates installation, resulting in faster and more cost-effective construction.

Gooplast provides a durable and high-performance alternative to EPS filling, offering improved strength, stability, and long-term reliability. Adjustable height configurations from 5 cm up to 300 cm allow flexible floor elevation for residential, commercial, and industrial applications requiring lightweight filling.
