Erosion Control Mat Applications
Environmentally sensitive areas need all-natural biodegradable erosion control mat solutions. An erosion control blanket for steep slopes will handle heavy flows and different site conditions. One of the best things about the coconut coir mat is its ability to encourage vegetative growth and establish natural erosion control. This can be accomplished through seeding the ground before or after installation of the coco coir mats because of its open weave design.
Coco Coir Mat Frequently Asked Questions
Installing coconut coir mat is not a difficult task but requires careful consideration of site conditions and planning. If you wish to seed the area to establish vegetative growth, this should be done before you install the coconut coir mat, if the mat in question has a small weave design. Coir mat 90 is an erosion control mat that has an open weave design, so seeding can be done before or after coconut coir mat installation. Next comes the trenching of the ground at the bottom and top of the erosion control area. Once you've measured your coco coir mat, you unroll it and lay it in the direction of the water flow. Properly installing your erosion control mat will mean using the proper installation accessories.
For proper installation of coco coir mats, you need the proper tools. Overlap your erosion control mat rolls with a minimum of 6 to 8 inches. Once your erosion control mat has been laid out, secure it in the top trench with U-shaped metal staples. You could also use wooden stakes. The top and bottom ends of the coconut coir mat should be secured to ensure the proper of installation of the coco coir mats.
