Sticking Stones | Studio Agne

In the Sticking Stones project, Studio Agne investigates how historical adhesives based on wood tar can be revived. In the past, natural adhesives like these were used to repair and join stone. The project builds on ongoing research at TU Delft into medieval stone adhesives and explores how waste streams can serve as binders and fillers. These offer an alternative to the synthetic, fossil-based grouts and adhesives currently in common use. The research combines material analysis, laboratory testing and application studies on stone, brick and ceramics. The intended outcome is a series of proof-of-concept adhesive systems that enable restoration and reversibility in the built environment, with reduced reliance on primary raw materials and petrochemical building products.
