We are building hundreds of new apartments and parking spaces in Helsinki’s Koskela neighbourhood in preparation for its vibrant future.
Earthworks and foundation engineering
Earth works is needed for many construction projects and it plays a particularly important role in infrastructure construction.

Foundation engineering from small projects to large urban development projects
We have a wide range of civil engineering equipment, modern technical equipment and a skilled team that is able to implement projects from the foundation construction of individual apartment buildings to large urban construction projects, such as railway engineering.
We use the option most suitable for the structure of soil in each earthworks and foundation reinforcement project, such as stabilisation, retaining walls and anchoring or piling. We also perform quarrying.
Tips for choosing the appropriate implementation model
The implementation form of the construction project is important for the success of the project. In the project model guide, you can find different project models, the kinds of projects the model is suitable for, and the benefits and challenges of the different project models. Download the project model guide so you can choose the right implementation form for your project.
The type of earthworks is selected as needed
Column and deep stabilisation are suitable for the reinforcement of soft underlying soil and for road, field, yard and street areas. Pile slabs are used for the foundation reinforcement of roads, railways and fields subject to heavy loads in demanding, fully rigid structures. Mass stabilisation is a foundation reinforcement method used in massive soft and loamy silty soils. It can be used instead of replacements of soil of as much as 4–5 metres, thereby conserving non-renewable gravel resources.
Reinforced concrete piling is a traditional foundation reinforcement method used in street and bridge construction, for example, as well as in the construction of buildings. Traffic routes, bridges and buildings subject to heavy loads are often supported by means of pipe and bored piles. Excavation piles, on the other hand, are customarily used in projects requiring very high loads, such as bridges and the foundations of machines.
Quarrying is sometimes needed in the foundation engineering for buildings. The retaining walls of building pits are usually realised by means of sheet piles and support elements. Difficult and deep excavations are also supported using dam walls implemented by means of excavation piling. The anchoring of the retaining wall is used in earthworks for tensioning against the soil and water pressure. Concrete supporting walls are often needed at the edges of open cuts to support the surrounding soil layers.
The foundations of a building may require renovation or renewal during the building’s lifecycle due to the rotting of timber piles, for example. Such work is usually executed by transferring the loads of the building on new piles using a variety of available methods.
If necessary, we also perform special drilling in sites with earthworks and foundation engineering, as well as tensioning in bridge and other projects.
