This document discusses different types of flooring materials, including structural glass flooring which is used between floors and has a thickness of 10-30mm, marble flooring which is used where sanitation is important like in hospitals due to its hard and durable surface, PVC flooring which is laid on concrete but can be slippery so is used on walls, and asphalt flooring which comes in tiles, terrazzo and blocks and is dustless, elastic, durable, waterproof and non-slippery making it suitable for places like chemical labs.
