About us
Proven Infrastructure Expertise Since 1948
When a project's success comes down to expertise, equipment and reliability, you choose a partner that has proven itself for almost 80 years. We build the foundations on which society grows.
Built on Experience
Founded in 1948, Niskasen Maansiirto Oy has grown from a small local operator into a well-known and reputable contractor and partner for infrastructure projects and specialised earthworks in Northern Finland. For nearly eight decades, we have built our reputation on reliability, expertise and quality.
Our story began with an old army artillery tractor, a bulldozer called the International, which was used to cut ditches across the bogs and clear land for settlements in the post-war reconstruction era. As the years went by, the company expanded into public works, while our fleet grew to include excavators and haulage equipment. At the turn of the millennium, we entered the piling business with a single rig. Piling would soon be followed by further investment in equipment and services for retaining walls and excavation shoring. As the years have passed, our business has steadily grown towards the role of a main contractor for infrastructure projects. With our four piling units and one unit for retaining walls, we are a well-established operator known for our quality. We are best known for specialised and demanding projects. As a new service, we also offer drilled piling (DTH).
Yet our story is much more than equipment, specialisation and projects. Our story is one of trust.
Whether a municipality needs a water network or sewer, a contractor needs challenging earthworks or an industrial project needs a contractor for demanding piling, we answer the call. We pride ourselves on being the one partner a customer can trust to deliver. This trust is what we, Niskasen Maansiirto, are known for, year after year.
Originally from Haapajärvi in Northern Ostrobothnia, we have expanded our operations across a wide area of Finland and Sweden. Our expertise covers earthworks, municipal utilities, driven and drilled piling and retaining walls. Our modern fleet and use of the latest available technologies keep us at the forefront of a developing industry.
Niskasen Maansiirto's greatest strength is our people. We pride ourselves on being a solution-focused, forward-looking team that tackles challenges head-on. Dwelling on problems and indecisiveness are simply not part of our habits and philosophy. Our people combine a down-to-earth attitude, strong expertise, an open mind and Ostrobothnian tenacity. We see our long history as an asset. Few contractors can claim to have been a part of building up Finnish infrastructure for nearly eight decades. Every completed contract, every site completed right the first time is part of our story, building Finnish society from one generation to the next.
Today, Niskasen Maansiirto Oy operates as part of the NYAB Group, combining our specialised expertise and local knowledge with the resources and opportunities of a larger organisation while retaining the core values on which our reputation has been built: reliability, quality and pride in our work.
We build the foundation for our society to grow on.
