GreenArmor System, Your Ultimate Guide

Bridging the gap between robust engineering and ecological sensitivity, the GreenArmor System ingeniously combines the strength of hard armor solutions, like concrete or rock, with the lush, aesthetic appeal of vegetative cover. This guide delves into the intricate workings of the GreenArmor System, exploring its unique components, such as the innovative Futerra Turf Reinforcement Mats (TRMs), and shedding light on its multitude of benefits.

What is the GreenArmor System?

Used for erosion control and environmental restoration GreenArmor System combines the strength of a hard armor solution like concrete or rock with the environmental benefits and aesthetic appeal of vegetative cover. GreenArmor's three-dimensional matrix core offers unmatched synergy with high performance hydraulically applied mulches.

How does the GreenArmor System work?

While the GreenArmor System is a reliable replacement for hard armor, it is also an excellent alternative to traditional stitch-bonded and densely woven TRMs. It begins with the unique design of Futerra Turf Reinforcement Mats (TRMs). To create a homogeneous matrix, Futerra TRMs are made of continuous nylon monofilaments thermally fused at their intersections. Unique because 95% percent of its three-dimensional matrix is open space, it does not inhibit vegetation establishment and provides maximum reinforcement of plant root systems. When fully vegetated, Futerra TRM can withstand water velocities as high as 30 feet per second and shear stresses of 20 pounds per square foot! Futerra TRMs are available in various designs that offer varying performance to meet your design needs in the most cost-effective manner.

What are the benefits of the GreenArmor System?

Providing immediate erosion control and aiding in environmental restoration, the GreenArmor system offers several significant benefits such as:

• Enhanced long-term stability against water and wind erosion
• Rapid establishment and integration of vegetation for ongoing soil stabilization
• Support for local biodiversity through the use of native plant species
• Creation of habitats for wildlife in restored areas
• Aesthetic improvement of landscapes, blending engineered structures with natural surroundings
• Reduced soil loss and sedimentation in adjacent water bodies

What are the best applications for the GreenArmor System?

Relatively easy to apply with standard construction equipment, the GreenArmor System’s process involves laying down and anchoring high-strength turf reinforcement mats, followed by hydromulching the targeted area. This is a straightforward and relatively quick process, making it a practical option for numerous projects with tight timelines.

Is the GreenArmor System difficult to maintain?

Generally not difficult to maintain once installed and the vegetation has been established, maintenance is minimal and consists of occasional trimming or replanting of vegetation and landscaping care best practices.

What is the lifetime value of the GreenArmor System?

Due to its durability once vegetated and the sustainable nature of its design, the GreenArmor System's lifetime value is high. While the initial material costs might be higher than some traditional erosion control methods, the less expensive installation cost, reduced maintenance requirements, and the extended lifespan of GreenArmor Systems can lead to considerable cost savings over time.

Using GreenArmor System for Slopes and Channels

Implementing the GreenArmor System for slopes and channels involves steps to ensure effective installation and optimal performance. Here's a step-by-step guide:

1. Site Preparation:
A. Clear the slope area of debris, rocks, or vegetation that might hinder the installation.
B. Grade the slope to the desired angle, ensuring stability and uniformity.

2. Base Layer Application:
A. If necessary, apply a base layer of soil or other material to provide a stable foundation for the turf reinforcement mats (TRMs).

3. Laying Turf Reinforcement Mats:
A. Roll out the TRMs across the slope, starting from the bottom and working upwards.
B. Overlap the edges of adjacent mats by a few inches to ensure full coverage.
C. Secure the mats with staples or stakes, especially on steeper slopes.
Burying the system into perimeter trenches may also be necessary, depending on the application, to mitigate the risk of the system being undermined.

4. Seeding and Planting:
A. Apply a seed mixture or plant seedlings appropriate for the local climate and soil conditions.
B. Ensure even distribution of seeds or plants across the entire area.

5. Initial Watering and Care:
A. Water the slope thoroughly to encourage seed germination and plant establishment.
B. Protect the area from erosion during the initial growth phase using temporary barriers if necessary.

6. Channel Preparation:
A. Clean the channel area, removing debris and ensuring a smooth surface.
B. Shape the channel as required, paying attention to flow lines and drainage patterns.

7. Installing TRMs:
A. Lay the TRMs along the channel bed and sides, ensuring they conform to the channel's shape.
B. Overlap the edges according to the channel's flow direction, and securely anchor and trench in the mats to prevent displacement by water flow.

8. Vegetation Establishment:
A. Plant or seed the channel with species that are tolerant of wet conditions and can thrive in the aquatic environment.
B. Consider using plants that can withstand periodic flooding and water flow.

9. Maintenance and Monitoring:
A. Regularly check the channel for signs of wear, especially after heavy rain or flooding.
B. Maintain the vegetation, ensuring it remains healthy and capable of reinforcing the TRMs.

10. Long-Term Care:
A. Over time, ensure the vegetation is well-established and the channel remains stable.
B. Periodically clear the channel of debris to maintain effective water flow.
