Timber and concrete

It is in the name, and on the site.

Tre og betong is Norwegian for timber and concrete. A frame going up in one place, a slab poured over heating pipes in another, and the concrete work that carries a power station or a sports hall.

Standards

How we build.

  1. 01

    Quality, safety and the environment

    A consistent focus on all three, from the start.

  2. 02

    A short chain of subcontractors

    Fair wages and working conditions, in line with Norwegian law and rules. So we keep the number of subcontractor tiers under us limited, and we check all our suppliers and partners.

  3. 03

    Buildings with a long life

    We have always been after flexible solutions, and we build for a long service life. Today that means greener ones too.

Work with us

We hire for the long term.

We are always looking for skilled craftspeople. We mainly look for people with ties to the region, who want to live and work on Helgeland.

Apprentices are welcomed here, and work beside experienced people on modern equipment.
