Opus signinum is a type of ancient Roman mortar made from a mixture of lime, sand, and crushed pottery fragments, which was often used in the construction of floors and waterproof structures. This material was valued for its durability and ability to create strong, water-resistant surfaces, making it ideal for public amenities such as baths, fountains, and aqueducts. The use of opus signinum reflects the Roman innovation in urban infrastructure and their emphasis on functionality and aesthetics in public spaces.
