The construction of buildings is responsible for 36% of EU carbon dioxide (CO2) emissions. Concrete has been an excellent choice in building construction, yet it produces 0.5 tons of CO2 per 1m3 of concrete used. The EU has already set binding targets for CO2 reduction for which alternative safe, carbon-neutral building methods will be crucial. If a substantial reduction of CO2 emissions is to be achieved, conventional construction practices must be reassessed. Timber presents itself as an alternative to concrete with a much lighter carbon footprint (absorbs and stores 1 ton of CO2 per 1 m3). However, despite offering the potential as a sustainable building material, timber slabs currently only allow a uniaxial load bearing action. Thereby, in comparison to reinforced concrete slabs, timber slabs often result to be thick, expensive and complicated to build. To establish a structural solution equal to concrete slabs, TS3 present their proprietary butt-joint technology capable of biaxial load bearing and the possibility to build timber structural elements at any length and size. This technology represents the next generation of timber construction. Timber slabs now become viable with spans of 8x8m and loads of 500kg/m2, with free-form shells being possible too.
