Aggregates: the way you need them

Our production, logistics and sales are not isolated processes, but part of our system. We provide you with a single contact whenever and wherever you need standardised aggregates for road, water, concrete or railway construction.

We use state-of-the-art technology in our quarries Jelsa, Tau, Dirdal and Larvik to quarry a full range top-quality aggregates. We have a virtually inexhaustible source of granodiorite, quartz diorite, syenite, granite and gneiss for aggregate in varying fractions for your particular application.

Mibau and Stema also supply armour stone for hydraulic engineering and blocks for erosion control as well as breakwater and pier construction.

Rounding off our product range we can also provide sand and gravel from a number of gravel pits.
