When Söderfjärdsbacken Daycare in Malax was completed in summer 2025, more than 100 children got new premises for their daily activities. An important part of the 1,600-square-meter building is its approximately 100-square-meter civil defense shelter. For the project’s main contractor, Byggtjänst H-E Storlund, JTK Power was a natural partner from the outset.

Completed in 2024, Savilahden Luola in Kuopio is a large civil defense shelter built into the bedrock, with capacity for approximately 7,000 people. In normal conditions, the facility serves as a sports and event centre with capacity for around 2,500 people. JTK Power supplied the shelter with custom-made double and single civil defense shelter doors, hatches and more than 500 other civil defense shelter components.

In 2017, we supplied pressure doors and gas-tight doors for the underground facilities in Jätkäsaari. This is an S3-class civil defense shelter.
