PERMANENT SITE SOLUTIOn
Flexamat® is a vegetated concrete block mat utilized for stabilizing slopes, channels, low water crossings, inlet/outlet protection, and shorelines. It consists of concrete blocks (6.5in x 6.5in with a 2.25in profile) locked together and embedded into a high strength geogrid. There is 1.5in spacing between the blocks that gives the mat flexibility and allows for optional vegetation growth. The mat is packaged in rolls, making transporting and installing Flexamat® efficient.
Tied Concrete Block Mat is a generic term for Flexamat.
