Erosion & Sediment Control
Erosion is a natural process of land degradation. Water and wind are the two primary causes of erosion and sediment and account for about 84%; however, human activities have increased erosion and sediment significantly.
Erosion and Sediment whether wind, rain or from human causes on slopes and hillsides without ground cover create both "on-site" and "off-site" problems because nutrient-rich soil particles are dislodged, and the effects of the dislodged particles are multiplied by the gathering speed of the water and force of the winds upon the slope or hillside. Making erosion a significant environmental problem. Therefore, how you control erosion on slopes and hillsides matters because there is always potential for erosion and sediment.
In urban and construction areas erosion and sediment control become a problem when dislodged soil particles clog storm drains, which causes flooding and infrastructure damage.
Erosion and Sediment Control is the practice of preventing or controlling the effects of wind, water or human activities in land development. Effective erosion control handle surface runoff and are important techniques in preventing water pollution, soil loss, wildlife habitat loss and human property loss. Erosion and Sediment Control is often part of storm water runoff management plan, and they often involve the creation of a physical barrier, such as vegetation or rock, to absorb some of the energy of the wind or water that is causing the erosion and are often implemented in conjunction with sediment control required by local governments when doing construction.
The primary methods for controlling erosion and sediment are:
Geogrid: A geogrid is geosynthetic material used to reinforce soils and similar materials. Commonly used for soil reinforcement applications such as retaining walls, steepened slopes, bridge abutments, embankments, and embankments.
Erosion Control Blanket (Woven + Non-Woven Geotextile): Erosion Control Blankets prevent soil erosion and are used for soil filtration, drainage, separation, and reinforcement. Cost-effective environmental alternative to traditional construction materials. Our Erosion Control Blankets are manufactured in Canada and consist of a machine produced mat of clean straw and/or Coconut combined with light, photodegradable, bio-degradable, or rapid degradation netting (single or double netting). This combination produces strong and effective natural organic netting that protects vulnerable areas from all weather conditions, while providing ideal growing conditions for all types of grasses and legumes. These blankets are designed to protect seed and soils for up to 12 months; after the blanket breaks down the vegetation keeps the soil in place. These blankets are designed for use on projects with moderate slope or moderate waterways.
Gabion Baskets: Gabion Baskets are also used for erosion control for bank stabilization, channel linings, and weirs. Ideal where a retaining structure is required which is also aesthetically pleasing and environmentally friendly. Permeable, allowing environmental growth and preservation.
Armour Stone: A natural quarry stone. Durable and erosion resistant. Used as a retaining wall.
Turf Reinforcement Mat: Designed for use on critical slopes and channels requiring permanent erosion control and turf reinforcement. Available in polypropylene, polypropylene/coconut, & polypropylene/straw.
Slope Interruption Devices: Elongated tube of compacted straw and/or other fibers wrapped in UV stabilized degradable tubular polypropylene plastic netting. Used for temporary erosion and sediment control applications. Designed to allow runoff/water to penetrate through the fiber while reducing sediment migration.
Turbidity Curtain: A geosynthetic barrier made with high strength geotextile or vinyl fabric, equipped with a heavy- duty float and ballast weight chain system that suspends the curtain in the water. Works as a shield to protect aquatic ecosystems by stopping solid particles from going into aquatic environments.
Hydraulically Applied Products: Have special cross-linking bonding agents that when dried create a matrix over the soil, drastically reducing soil loss and aiding seed in germination. The two types of hydraulically applied products are:
Bonded Fiber Matrix (BFM) is a hydromulch and represents a breakthrough in erosion control technology. It conforms to the contours of the ground and dry to form a Bonded Fiber Matrix blanket. After drying, the matrix can be hydrated repeatedly and will hold soil and seed without washing away. As vegetation takes hold, the Bonded Fiber Matrix slowly decomposes to enrich the soil. Bonded Fiber Matrix combine the erosion protection of blanket, and the ease of hydraulic application. It is a one or two-step erosion control system that revolutionized the practice of soil conservation.
Fiber Reinforced Matrix (FRM) is a hydromulch, engineered with pasteurized wood fibers, dispersable synthetic fibers and exclusive soil-bonding agents for immediate and effective erosion protection on challenging terrain, even during hard rains. The nontoxic matrix formula maintains fiber flexibility and loft for impact resistance, air circulation and moisture retention that promotes seed germination and plant growth.
