Hard Armor is a term used to describe permanent stabilization solutions, which exist in many forms, both vegetated and non-vegetated. Such solutions are indicated when water velocities in channels or ditches require very robust reinforcement to prevent erosion problems.
Filter Point Concrete Linings with filtration points (drains) provide erosion-resistant, permeable concrete linings for ditches, channels, canals, streams, rivers, ponds, lakes, reservoirs, marinas, and protected port and harbor areas. Filter Point Concrete Linings have a cobbled surface and a relatively high coefficient of hydraulic friction in order to achieve lower flow velocities and to reduce wave run-up. The filtration points provide for the relief of hydrostatic uplift pressures, increasing the system’s stability.
