Rock engineering and geology

Our experts are ready to help you with all challenges related to rock engineering, geology, and rock mechanics in your project. We have been involved in several significant underground and above ground rock engineering projects, designing a new sustainable urban environment, traffic routes, and enabling the transition of green energy. Contact our experts and ask more about our services when you need help with rock engineering or geology!

Rock engineering, geology, and rock mechanics

Our expertise comprehensively covers the design of underground rock spaces and aboveground rock structures, from preliminary studies to detailed designing and site services and later to maintenance designing. We can also act as the main designer of an underground rock facility design project and participate in the layout design. In addition, we have specialized in inspections of old rock spaces and slopes and their repair planning. Our strength lies in seamless cooperation with other design disciplines and teams in extensive and demanding mobility, industrial and construction projects and in different project formats from traditional models to alliances and EPCM assignments.

Rock engineering has become more and more important and common in Finland in recent decades as important infrastructure, such as rail traffic, parking and water supply have increasingly begun to be placed underground in bedrock. This frees up space on the ground for other activities and, on the other hand, enables a safe and undisturbed environment for critical functions in society. In addition, new fossil-free forms of energy production, such as wind turbines, small-scale nuclear power plants and heating and cooling plants, as well as energy storages, needs reliable and cost-effective rock engineering as part of a large and long-term investment.

Many underground spaces and rock slopes built in Finland during the 1900s are reaching the end of their technical service life, and their original design and implementation no longer meet today’s technical and safety requirements. This creates a need for inspections, surveys and repair planning of old rock slopes, shafts, railway and other tunnels and rock shelters. In addition, old rock spaces can be modified or expanded to meet new uses.
