Carrières de Maffle and Marbrerie Crombé are two family-run SMEs managed by the Crombé family, which has been active in the natural stone processing sector for over 125 years. The companies supply stone for construction and renovation projects, and also reclaim materials. Marbrerie Crombé restores, sells and installs old fireplaces. Carrières de Maffle transforms reclaimed stone into slabs and paving stones, among other things, or any other product on request. For example, thick columns can be split into strips of a few centimetres to make terrace slabs. Or granite slabs can be cut to make window sills.
