PEC-MAT
PEC-MAT® is the permanent soft armor solution for many hard armor applications. PEC-MAT protects seed and soil during germination and provides long term turf-reinforcement for established vegetation. Its dense web design guards seed and soil from wind, rain and storm-water forces, while retaining moisture and solar energy to promote seedling development. The new vegetation's roots entwine with PEC-MAT to produce a reinforced turf capable of withstanding flow velocities up to 20 feet per second and a shear stress of 6 pounds per square foot.
