Reparation of Kuhalankoski dam, Forssa

Underwater construction

Approx. 100m3 of underwater casting

The work included different kinds of concrete jacketing.

A work dam was built to enable the safe completion of repair work.

The structures of the dam were renewed, e.g. jacketing of concrete structures as winter work, concreting work on the lower bed and hatch repair work.

After the construction of the work dam, the water level in Loimijoki River was closely monitored according to a separately prepared inspection programme.
