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.
