Installation of Coconut Coir Fiber Mats
Question regarding Installation of Coconut Coir Fiber: Can you tell me more about installing Coconut Fiber Coir-Logs?
Answer: Thank you for contacting Granite Environmental. I would be happy to tell you more about our Coir Products. Our Coir Logs are strong and flexible. They are compact coir cores which form a Coir Web for superior filtration, covered by exterior coir mesh netting.
Coir logs aid in the stabilization and re-vegetation of sites where you encounter steep slopes or exposure to waves along or currents which cause instability on a site. The extended longevity (2-4 years) of Granite coconut fiber products and also superior performance in the field has helped make it a favorite among landscape architects, contractors and engineers for the installation of coconut coir fiber.

Installation of Coconut Coir Fiber
- Grade the Shoreline. If the shoreline or streambank that needs restoration is severely eroded, grade the shoreline or streambank according to the natural terrace of the area (2:1 slope is generally recommended). Immediately, place an erosion control blanket along the graded slope (refer to blanket installation guide) to prevent erosion.
- Place Coir Rolls: Rolls should be placed along the top of the bank where the water level is 1/2 to 2/3 of the coir roll's height. Proper submersion of coir rolls is important for successful establishment of vegetation. Tie the ends of adjacent coir rolls together with (6mm) 0.25 inch thick coir twines (BioD-Twine). Use extra loops of coir twine through the outer netting of adjacent coir rolls. Use of 4" x 2" wooden wedges with a 3-4" nail at the top (4" x 2" x 36") for 12" diameter coir rolls for regular flow and soil conditions is recommended for coir roll installation.
- Placed a Wooden Wedge: Place a suitable length wooden wedge at 36" (24" spacing for high flow conditions) on the waterside if the bank will support the coir rolls on the landside. If the bank does not support the coir rolls, place wooden wedges on the landside as well as on the waterside. Pound the wedges down so that the nail is pressing the coir roll at the top.
Tying coir rolls to wedges with several loops of coir twine will provide extra support. Bend the ends of the first and the last coir roll towards to the shore and dig them into the bank. This will avoid water getting behind the coir rolls and will prevent pull-out.

Planting with Coir Logs
Begin planting on the coir rolls after the coir rolls have been installed properly. Select plant plugs of the preferred native wetland plants. If sufficient water is available, place plant plugs into the coir roll by pulling the coir roll fibers apart with the fingers and gently pushing the plug deep into coir roll.
In case of high density (9 lbs/cu. ft) coir rolls, some difficulty may exist in planting into the coir rolls. In this situation, be sure to place the plants in soil adjacent to the coir roll.
