2. Construction details

All of the construction we will inform you about this time is floor slab replacement work. In this work, the concrete floor slabs that have been damaged due to deterioration and the increase in the number of large vehicles will be replaced with new, more durable prestressed concrete slabs. In addition, high-performance floor slab waterproofing is applied to the waterproof layer to prevent deterioration of the floor slab.
