BEBO Concrete Arches

BEBO arches are precast component bridging systems that provide great strength in relatively light concrete shell structures.

First tested in 1965, the BEBO arch capitalizes on soil-structure interaction between the reinforced concrete arch/foundations and the surrounding fill. Spans range from 3.66m to 31m, and are uniquely capable of ultra low-profile geometries – with span-to-rise ratios as low as 10:1. The versatility of the system makes it attractive for a multitude of applications.

BEBO structures are manufactured and sold under a licensing agreement with BEBO A.G. of Zurich, Switzerland.
