Industrially Manufactured Net-Zero Timber-Earth-Slabs for Multi-Storey Timber Construction

The production of floor slabs, with their high requirements for fire protection, thermal mass, and sound insulation, is a central challenge in multi-storey timber construction. The research project explores the possibilities of timber-earth slabs (TES) that can meet such high demands while being fully recyclable. TES comprises a hybrid structure, which aims to combine the strong tensile properties of wood with the beneficial properties of earth in terms of thermal mass, thermal activation capabilities, fire resistance, and sound insulation. It integrates a novel material technology capable of casting earth with low water content and combines it with robotic technology that enables the bespoke fabrication of a filigree wooden structure tailored to mechanically interlock with the earth infill.
