Sustainable Coastal and Bank Protection

Economical alternative to traditional constructions

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.

Long-term stabilityThe 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.
