This document provides an overview of bubble deck slabs. It discusses that bubble deck slabs are constructed using high density polyethylene hollow spheres placed between steel reinforcement on the top and bottom of the slab. This creates voids and reduces the slab weight by 30-50% compared to conventional solid slabs. The advantages are less material usage, faster construction, reduced costs, and lower environmental impact through less emissions. There are three main types of bubble deck slabs: filigree elements, reinforcement modules, and finished planks. The document compares the structural behavior and costs of bubble deck slabs to solid slabs.
