The structure of the development anti-flood barriers from recycled plastics is composed from metal and plastic sources. When designing the geometry and constructing the barrier, the first stage was to design a structure based on the shape of unified blocks made from PP and PE. The last generation of metal construction was constructionally optimized by renowned producer KONSTRUKTA-Industry, a.s.. Unified plastic blocks were designed in Slovakia at Chemosvit Environchem, a.s. in cooperation with Chemosvit; the focus was to produce blocks made from recycled materials and their subsequent application for beneficial use. The structure underwent numerous optimization processes including load field trials, finite element analysis (FEA) and internal/external stability analysis. Production documentation, prototypes, and field tests were also performed. The latest changes to the design are being performed in order to prepare it for mass production. Our development is the subject of protection [Soos 2011], [Soos 2013], [Soos 2014b], [Soos 2014c], [Soos 2014d]. The latest generation of the strategy is in Fig. 1.
