Funicular floor system


Technology Description

The funicular floor is a thin concrete element consisting of vaults and optimised stiffening fins. The thickness of the slab and fins is no more than 20 mm, which allows 70% of the concrete to be replaced by low-density insulation materials to improve the thermal performance of the floor.

Relevance for Net Zero

The funicular floor system uses (on-average) 70% less concrete than a traditional slab and uses no reinforcement. It also has better environmental performance.
