Needle Dam Installation at Isohaara Hydropower Plant

We worked as a subcontractor for Ramago Oy on the installation of a needle dam at the Isohaara hydropower plant. The needle dam was installed in front of the spillway gate. Our tasks included inspecting and cleaning the bottom sill, installing the needles, and performing sealing work.

The installation and sealing process proceeded according to plan, and we achieved a solid and satisfactory result for the client. All diving operations were carried out safely, following the prepared safety plan for the project.
