Coir Mat 90


The Strongest Erosion Control Coir Mat

Coir Blankets for Slope Stabilization and Erosion ControlCoir mat 90 is one of the strongest options for erosion control, stabilization, and vegetative growth. Featuring a high strength woven coir twine, our coir erosion matting can handle slopes up to 1:1 and areas with flows up to 16 fps. As our strongest erosion control coir mat option, it is ideal for demanding restoration projects with its ability to naturally stabilize areas affected by erosion.

As with all of our coir erosion control matting, coir mat 90 is designed from 100% natural coconut fibers that will biodegrade over a period of four to six years.
