Groynes and Breakwaters

Sustainable Coastal and Bank Protection

Conventional stone fill structures generally comprise a core, several filter layers and a top layer. Industrially manufactured geosynthetics and tailored system solutions incorporating custom-fabricated units allow the optimization of structural geometries and cross-sections. Furthermore, the use of locally sourced materials such as sand vastly reduces the need for cost-intensive material shipments, e.g. of armour stone. The straightforward installation process and the use of geosynthetics of certified quality help to minimise risks and avoid the irregularities typical of mineral filter layers. Moreover, filter-stable installation of the core containment system prevents any erosion of the core material.
