Coir Mat 70


Erosion Control Mat for Stabilization and Reinforcement

erosion and sedimentation control matsCoir mat 70 is a natural, biodegradable product used for slope stabilization, bank reinforcement, and wetland restoration projects of any size. 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 other erosion and sedimentation control mats, coir mat 70 has a higher strength that allows it to be used in areas with slopes between 2:1 and 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.
