Water works and shoreline construction

Water works and shoreline construction

We implement all kinds of shoreline and water works construction

We have participated in the development of both international and Finnish harbours. Our professional staff are able to slip form retaining wall elements as well as piled quay structures.

We have our own water works equipment for the execution of basin excavation and dredging. We have the tools necessary for the cost-efficient planning and implementation of stabilisation of the dredged sediment masses. We continuously develop our existing water works equipment. 

In order to improve the usability of shores and increase the value of areas, we have participated in the construction of new shoreline structures and the renovation of existing ones. We have also implemented projects in accordance with the wishes of the museum authorities, respecting the old structures. We are able to implement the dredging, element construction, stonework and all above and underwater work required for shoreline construction with high quality, cost-effectiveness and in environmentally sustainable manner. 

We use our own water works equipment in the dredging and excavation of waterways. If necessary, we are able to stabilise the dredged sediment masses using our own equipment and plan a cost-efficient implementation. We use our special environmentally friendly scoop in the dredging of contaminated soil. Read more about the remediation of contaminated soil.

Our water works construction equipment and professional personnel are able to perform many kinds of difficult tasks in demanding conditions. We have repaired lighthouses, set up new beacons, built underground foundations for bridges and developed wind power station foundations.

Beacons

Beacons are used for the controlling of waterway traffic and for navigation, built on water or near it on the shore. Beacons may be stationary or floating, lit or unlit. They are usually fitted with reflectors to improve visibility in when it’s dark.

Stationary beacons can be installed like piles by driving them until the load-bearing base or rock or by installing them into an excavated opening in the rock. Beacons may also be founded on a concrete caisson. The foundation method is selected based on the depth and the ground type of seabed.

Floating beacons are anchored to the seabed. The anchor chain may be tight or loose. A tight anchor chain does not allow the beacon to move around its anchoring point, whereas loose anchoring allows free floating.

Projects

  • Construction of beacons
  • Waterway controls
  • Safeguarding of shipping
  • Harbours and marinas
  • Repair and renovation of old beacons
