Erosion Control Mat for Stabilization and Reinforcement

Constructed from machine-spun woven bristle coir twine, our coir erosion mat provides a reliable layer of support that easily accommodates seeding and vegetative growth both before and after installation.

When compared to another sedimentation control mat, coir mat 70 has a higher strength that allows it to be used in areas with slopes up to 1:1 and flows up to 12 fps (feet per second). The standard life span for Coir Erosion Control Mat 70 is 4-6 years, depending on location and project-site conditions.
