Who we are
An integrated aggregates and civil-works operator.
KBS quarries, crushes and supplies specification-grade stone for road construction, mining and civil engineering across Namibia, controlling the full chain – in-pit extraction, crushing, screening and delivery.
The primary quarry at Aris, near Windhoek, sits on a phonolite formation meeting Roads Authority hardness and gradation standards that most Namibian rock cannot. Quarry and crusher are co-located, keeping haul distances and unit costs low.
The Aris quarry face and stockpiles.
Operations
Three quarry sites, one standard of supply.
Each site is matched to its market – road-spec aggregate from Aris, regional construction supply through the Karibib corridor and the north.
