The collection is named after the cement powder code 325 and the concept of a laboratory as a place for creative experimentation. It comes in three different surfaces: BASE, minimalist smoothed concrete; FORM, inspired by concrete removed from formwork; and METAL, reproducing vintage-look reinforced concrete. LAB325 features a wide range of solutions, from WIDE large-size slabs (160×320/120×280 cm) to 6 modular sizes with a thickness of 9 mm for indoor floors and walls, and an exterior slab with a grip surface and 20 mm thickness.
