Permanent Erosion Control
Flexamat® is a permanent erosion control mat utilized for stabilizing slopes, channels, low water crossings, inlet/outlet protection, and shorelines. Tied Concrete Block Mat is a generic term from Flexamat. It consists of concrete blocks (6.5" x 6.5" with a 2.25" profile) locked together and embedded into a high-strength geogrid. There is 1.5" 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. It is manufactured with various underlayments, determined by onsite conditions.
Work with Nature, Not Against
Incorporating perennial vegetation into storm water treatment plans will encourage the benefits of phytoremediation which is the direct use of living green plants for the removal, degradation or containments of contaminants. The establishment of perennial vegetation increases infiltration of storm water runoff into the soil, increased removal pollutants found in road and parking lots runoff (oils & grease, metals, brake dust, salt, garbage, nutrients) through filtration and phytoremediation. The perennial vegetation also reduces or eliminates the thermal impacts storm water runoff by shading the concrete blocks from sunlight and aiding in infiltration and filtering the runoff, unlike rip rap or other armor alternatives.
