Hybrid-Doweltreeslab

The Hybrid-Doweltreeslab (HYB-D) is composed of the concrete layer above and the solid wood dowel-beams below. Two dowel-beams are sawn from each tree trunk, then dried and profiled. Depending on the requirements of the structure, different heights and widths of dowel-beams are available and are offered in a wide variety of qualities and types of wood. The shear-resistant connection between the elements occurs via a patented system of a connection profile in combination with notch connection, which together guarantee the high load-bearing capacity of the system! Due to the patented construction, the Hybrid-Doweltreeslab can be stretched up to 9.00 m with an element width of up to 3.00 m.
