The prerequisite for a long life span is durable load bearing structures, including the floors. Hollow core floors will retain their structural capacity for 100 years and more because of their high concrete strength, low porosity and sufficient cover to the prestressing reinforcement. The manufacture has to respond to the national product standard (e.g. European Product Code EN 1168), and is strictly controlled according to a system of self-control, supervised by an accredited external body.
