Waterway Bed Protection

Economical Alternatives to Conventional Stone Fill

Unlike conventional stone revetments, concrete mattresses allow the installation of slender, efficient, heavy-duty revetments, e.g. for boat landings, even at greater water depths. They can replace stone layers of several metres thickness: Providing a robust alternative scour protection solution. Prefabricated sinking mattresses or sand mats can also be used for conventional stone revetments to optimize construction thickness or ensure controlled installation. Geotextile containers allow the placement of filter-stable layers both under exposure to strong currents and for scour fill with steep slopes.
