Here at Curbed, we’re not immune to the charms of terrazzo, the suddenly ubiquitous material made from chunks of marble or stone set into concrete. From trendy restaurants to high-design apartments, the material is in the midst a serious comeback.
With terrazzo’s reemergence on the design world stage, there’s been some intriguing innovation in the centuries-old material-making process, which typically requires manually placing marble chippings in a pattern before casting them in concrete.
Meet Altrock, a new marble-based surface material from London designer Robin Grasby. Altrock terrazzos are made from a combination of stone waste products like marble flour, marble chips, and broken pieces from marble slabs sourced from interior projects. These materials are mixed with a bit of resin and then hand-casted into slabs that can be used for new products like tables, flooring, and countertops. Design-wise, Grasby opted for a “beautifully chaotic appearance” in which no two slabs are the same, rather than putting in place carefully arranged stone patterns.
Though Altrock is simply terrazzo by another name, it’s notable for using 87 percent recycled materials—and an on-the-nose perfect millennial color palette.
