Coir Matting 70 Details
If you need coir matting that can handle steeper slopes and higher flow conditions, Coir Matting 70 (also called Coir 700 Matting) is a dependable choice. This coconut erosion control blanket is designed for permanent and semi-permanent erosion control on 2:1 to 1:1 slopes where you want both performance and a natural, biodegradable solution.
As a heavy-duty coir blanket, Coir Matting 70 is capable of withstanding flows up to 12 fps (3.7 m/s). It weighs 700 g/m² and uses a 65% open weave to hold seed and soil in place while still allowing vegetation to grow through the mat. That makes it a good fit for coir erosion control blankets used on embankments, channels, banks, and other areas where you need reliable stabilization and long-term vegetative cover.
Standard roll sizes include 6.56 ft. x 165 ft., 13.1 ft. x 83 ft., and 13.1 ft. x 165 ft., so you can match the coconut erosion blanket to your site layout and installation methods. Installation is straightforward and maintenance is low-effort when used as part of a well-designed erosion control plan. See our detailed installation guidelines for best results.
