Longitudinal Protection

Longitudinal protection structures are hydraulic structures with their length parallel to the river flow. These structures are often built on, or supporting, existing natural banks and they typically extend for a considerable distance.

Riverbank protection solutions must be sufficiently robust and well-designed to counteract erosive forces generated by flow current and transported sediments.

Abrasion load due to materials carried by the flow is among the most critical forces exerted on riverbanks or on the toe of the banks. For this reason, we developed PoliMac, an exclusive polymer coating for double twist wire products to withstand mechanical loads and chemical attacks that impact river structures.  

Rigorous test campaigns and a deep understanding of the performance of our solutions enable us to make more cost-effective designs that will give our solutions an increased competitiveness in comparison to equivalent and alternative (traditional) systems. Bank protection constructed using Reno Mattress Plus can have a thickness reduction of up to 73% compared to traditional bank protection with Rip Rap. This enables significant materials savings and reduction of the environmental burden of the riverbank protection.

Our systems for riverbank protection are studied and optimized to find a balance between the demands of our societies and environmental equilibrium. In this regard, our solutions are designed to create ideal conditions for the natural re-vegetation of the bank; moreover, recent studies demonstrates that our nature-inclusive systems offer a natural habitat for living species, enhancing biodiversity through the protection of the benthos.
