Coir Matting Applications
Because of their biodegradable nature, the coconut erosion control blanket is great for environmentally sensitive areas like wetlands and protected areas. This all-natural coir matting provides strong erosion control while not adding harmful elements to the surrounding wildlife. When slopes and banks need stabilization and support from the effects of erosion, using a coconut erosion control blanket will aid in support of vegetation and natural erosion control.
Coir Matting Frequently Asked Questions
Coir mat 70 differs from other coir erosion control blankets in its weight. Coir mat 70 weighs 700 grams per square meter. This durability and strength sits between other coconut coir matting weights of coir mat 40 and coir matt 90. Coir mat 70 can handle higher flows than coir mat 40. Coir mat 70 is an erosion control blanket that can handle flows up to 12 feet per second. Shear stress also differs for different weights of coir blanket. Shear stress for coir mat 70 is 4.5 lbs./sq. ft.
The lifespan of a coconut erosion blanket will depend on several factors. You must consider your site conditions, the slope of your location, the flows you are experiencing, and the timeline of your project. Typically, coconut coir matting will last anywhere from 4 to 6 years, depending on specific site conditions.
