Main Engine Room | Structural Restoration & Reinforcement

The concrete roof slab of the main engine room in the power plant of Skyros Island had visible damages due to insulation failure that led to steel rebars corrosion. The slab has a span of approximately 15m x 40m and it rises 9.5m above the ground level and the power engines which produce energy 24/7. Specific parts of the slab was severely damaged with parts of corroded concrete falling, creating a significant danger for personnel and machinery of the power plant. Without obstructing the power plant’s operation the slab was structurally restored by applying proper, high-quality, cement repair mortars and chemical, corrosion inhibitors. The magnetic depiction of the remaining reinforcing rods of the slab proved that it couldn’t support the slab adequately. Thus, carbon fiber plates (FRP) were applied on the lower surface of the slab with use of a special 2-compound epoxy paste in order to restore its load bearing ability.
