Permanent erosion-control system for vegetated slopes

EnkaMat A20 is a high-performance erosion-control mat designed to protect slopes from eroding, which are subjected to high water velocities and moderate wave attack. It consists of a durable geosynthetic monofilament matrix with a flat structure on its lower face. The three-dimensional matrix is pre-filled with stone chippings. This permanent erosion-control mat is flexible enough to conform to curves and prepared ground profiles.

EnkaMat A20 is 22 millimeters thick and weighs more than 20 kilograms per square meter. It is the heaviest erosion-control mat available on the market today to support the establishment of vegetated slopes.

EnkaMat serves as a green alternative to hard armor solutions like concrete mattresses, gabions, stone setts or rock revetments (riprap), and to standard bank protection by means of wooden or concrete revetments. The prefilled EnkaMat A20 controls erosion below and near the waterline. The key advantage of EnkaMat A20: it allows the development of vegetation. With its high weight of 20 kilograms per square meter, the product offers immediate protection to applied seeding. The allowable flow velocity depends on the specific project conditions, flow duration and vegetation development stages. EnkaMat A20 creates an environment which is favorable for seed germination below the mat. The open structure of EnkaMat A20 stimulates fast plant growth and provides a foothold for its root system. The most appropriate vegetation type can be assessed by an ecologist, and will be based on specific site conditions and regional seed sources.
