Prestressed floor panels in a nutshell
Prestressed floor slabs are foundations made of prestressed concrete
Tendons are used to apply compressive stresses to the concrete. This so-called prestressing ensures that no or only low tensile stresses occur in the concrete, which concrete can generally only absorb to a small extent.
As a result, the slack reinforcement usually used to absorb the tensile stresses can be significantly reduced. At the same time, surface protection systems can be dispensed with and the thickness of the floor slab can be reduced in the best case. A distinction is made between prestressing without bond and prestressing with subsequent bond.
4 Key Benefits
Cost efficiency & material savings
By using pre-stressed floor slabs, the amount of reinforcement can be reduced by 30-50%.
This means that less reinforcing steel is required, which not only lowers material costs, but also reduces overall construction costs. In addition, the prestressing makes more efficient use of the concrete, which means that the slabs can be made thinner. In addition, the surface protection system can be dispensed with in accordance with EGS a, variant A1.
Improved construction quality & durability
The prestressing of a floor slab can completely prevent cracking, which leads to increased durability and impermeability of the structure. This is particularly relevant for water-impermeable structures such as underground garages, basements or infrastructure buildings, as cracks can often lead to leaks.
The absence of cracks also prevents the ingress of water containing chloride, which minimizes corrosion of the reinforcement. The BBV post-tensioning system is designed for a service life of up to 100 years and meets the highest technical standards, reducing maintenance and repair costs in the long term.
Sustainability & CO₂ reduction
The reduction in material requirements - especially for steel - saves considerable amounts of CO₂ emissions. For example, in one case study, up to 19 tons of CO₂ were saved compared to conventional construction methods by reducing the amount of reinforcement.
Less concrete and steel also means lower energy consumption for production and transportation, which significantly improves the ecological footprint of the construction project. In addition, the possible elimination of a surface coating means that regular repair measures are no longer necessary, which further reduces the environmental impact.
Made in Germany
BBV Systems has over 50 years of experience in the field of prestressing steel work and offers a comprehensive overall package for prestressed floor slabs.
The tendons are produced entirely in Germany by qualified specialists. This guarantees the highest quality standards, short delivery routes and sustainable added value in the region.
The prestressing work is carried out by our German-speaking and experienced BBV personnel. Thanks to this professional and flexible staff, we are also able to carry out tensioning work on Sundays and public holidays. This enables us to react quickly to project requirements, minimizes construction delays and ensures maximum efficiency on the construction site.
