Biaxial hollow core slab

In case of the biaxial hollow core slab, special displacers are introduced in order to reduce concrete consumption, whereas a wide variety of displacers are available on the market. Only after installation on site, the remaining cavities around the displacement bodies are filled with concrete. The main advantage is that approx. 1/3 of the deadweight is saved and the occurring payloads are discharged biaxially. In addition, very high spans can be achieved with low construction heights.
