Suomen Maastorakentajat Oy

Construction quality since 1987

Belief in our own expertise and a burning desire to deliver optimal quality for the client is the foundation on which Matti Haataja, Mauno Nieminen and Eero Ylhäinen founded Suomen Maastorakentajat in 1987. As experienced professionals in the infrastructure industry, they knew that this foundation would also ensure the firm’s growth.

Maastorakentajat has grown into a nationwide operator with core competencies that include concrete construction. The Group has extensive expertise, ranging from challenging soil conditions for foundations to turnkey deliveries.

A trusted operator for demanding infrastructure construction

Maastorakentajat rapidly gained a reputation as a skilled builder of power plants.

The company has also completed countless major infrastructure projects ranging from bridges and other demanding highway construction undertakings to area construction and various industrial installations.

In Maastorakentajat clients find a reliable partner with an experienced staff capable of implementing functional solutions to even the most demanding special construction projects.

We have a responsibility for a sustainable future

The company’s strengths have always included co-operation, responsibility and a human face in ownership. Its experienced staff share their expertise, seeking optimal solutions through open and direct interaction with both colleagues and clients. A human face in ownership especially means that the owner feels personal responsibility for the quality of a service or solution, and for the welfare of staff.

Responsibility has been part of Maastorakentajat operations since the very beginning. The company founders understood that building high-quality infrastructure also means taking responsibility for a sustainable future. Current Maastorakentajat staff members are all dedicated to accomplishing that mission.
