Cast concrete is a high-performance, pigmented concrete composite specifically developed for hand-casting sanitary surfaces such as washbasins. It combines CEM I 52.5R cement, micro-fillers, quartz aggregates, and dispersion additives to achieve high strength, low porosity, and a tactile aesthetic. The surface is sealed with an eco-friendly, water-based coating.

NOTES
Due to the handmade nature of the product, each unit may exhibit variations in color, structure, surface holes, and micro-pores. These characteristics do not represent flaws, but rather the authentic expression of the material. Tests are conducted in accordance with industry standards; results may vary depending on form, conditions, and application.
