Erosion control is the technique of preventing or controlling wind or water erosion in agriculture, land development and construction. Effective erosion controls are important techniques in preventing water pollution and soil loss.
Erosion controls are used in natural areas, agricultural settings or urban environments. The controls 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. On construction sites they are often implemented in conjunction with sediment controls such as sediment basins and silt fences.
EnviroRemedy employs the following methods in erosion control:
Gabions and Reno mattresses – A gabion is a cage, cylinder, or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building for slope stabilisation and erosion control. Our operations team has years of experience in the construction and installation of different types of erosion and sedimentation control structures.
Advantages of gabions in erosion
- Their modularity and ability to be stacked in various shapes unlike loose riprap; they are also resistant to being washed away by moving water,
- Gabions also have advantages over more rigid structures because they can conform to ground movement, dissipate energy from flowing water, and drain freely.
- Their strength and effectiveness may increase with time in some cases, as silt and vegetation fill the interstitial voids and reinforce the structure.
- They are sometimes used to keep stones which may fall from a cutting or cliff from endangering traffic on a thoroughfare
Riprap – Is rock or other material used to armour shorelines, streambeds, bridge abutments, pilings and other shoreline structures against scour, water or ice erosion. It is made from a variety of rock types, commonly granite or limestone, and occasionally concrete rubble from building and paving demolition. It can be used on any waterway or water containment where there is potential for water erosion.
