The project ran between May 2022 and May 2024.
The project developed and validated XLoc™, a resource-efficient, metal-free mechanical joint for cross-laminated timber (CLT) that replaces conventional screws. This innovation reduces CO₂ footprint, enables easier reuse, improves structural safety, reduces work injuries and speeds up installation. The joint is CNC-machined directly in the CLT panels, moving assembly steps from site to factory, increasing precision and cost effciency. Full-scale tests confirmed strength and functionality, and on-site installation exceeded expectations. XLoc™ supports a circular bio-based economy, strengthens CLT’s competitiveness against concrete, and contributes to UN SDGs 9, 11, 12, and 13.
