Erosion Control Blankets EROSION CONTROL TECHNIQUE ... • Allowable flow velocity can be increased by using a synthetic mulch layer, or increasing the strength of the mat reinforcing. Erosion Control Blankets and Mats The term blanket is usually used for lighter-weight materials and mat for heavier, more permanent ones, but both terms are often used interchangeably. EcoArmour is a synthetic erosion control blanket that has been designed to be sprayed through high pressure Hydroseeder equipment. However, a closer look at the results showed that even at flow velocities up to 6 m/s (20 ft/s) the TRM remained intact. Erosion control blankets are generally applied to soils subject only to sheet flow such as road batters. Available in both Single Net, and High Velocity/Double Net. Australian designed and manufactured, EcoArmour™ is a synthetic erosion control blanket that has been designed to be sprayed through high-pressure hydroseeder equipment. 167 0 obj <>stream ��/�)��#9b�T)�R����PS9��>Q Erosion Control Blankets Our erosion control blankets are effective in controlling erosion on slopes and channels, stabilizing soils long enough for re-vegetation seeding to establish on the site. Application of RECPs. High Velocity (HV)/Erosion Cotrol Blanket. TRMs are placed in steep areas, or where ground maintenance is challenging to access. 0000003891 00000 n Unvegetated, they reduce soil loss to less than 0.5 in. Erosion control blankets are usually woven from a chosen material and are meant to slow ... Coir logs supply protection to a stream-bank from erosion in areas with a low-velocity current. EcoArmour lasts a lot longer than traditional erosion control blankets. ... Shotcrete is the process of pneumatically projecting mortar or … The highly durable mats are also versatile enough to form around any contours of soil. Permanent: Permanent erosion control blankets are long-term erosion control solutions that do not degrade over time. B. Curlex High Velocity erosion control blanket (ECB) consists of a specific cut of naturally seed free Great Lakes Aspen curled wood excelsior with 80% of the fiber ≥ 6 inches in length. 5.11-1 SECTION 5.11 REVEGETATION AND SITE STABILIZATION Stabilizing a site with vegetation following any drainage improvement project is a critical component in reducing sedimentation and armoring the site against future erosion. These blankets are made with exclusive soft barbed interlocking curled Aspen excelsior fibers and are free of any weed seeds. x�b```b``�������� Ā B@1V� @�-��Sb�Z�J4 ��s���ȏ6=ߒ:'�I��[w�. h�bbd```b``�"��H�� �i�d�"��H� �ELV�e%��`��`�7@$W�k0Y"�U��t�V��$�����O20]�v# ��L�? Benefits of Using EcoArmour Safe and Easy Application Through HydroTruck equipment, 0000004312 00000 n High velocity winds are common during the south west monsoon and dry winds blow in March - April. Non-woven coir geotextile erosion control blankets (Coir ECB) are fixed at the top of the slope, by the side of the concrete edge drains of the stadium. 0 The various features listed above are displayed in Photos 6 to 13. Minimum Order: 15 Mats Applicability Dam spillways Plunge pools/stilling basins Channelized river and stream reaches Steepened river and stream reaches Canal drops Fish blocks or fish passage channels. Turf Reinforcement Mats (TRM) are a type of erosion control blanket used for permanent applications to stabilize hillside soil and to promote vegetation growth. 20605P Erosion control blanket; referring to products put in place to reduce the impact of raindrop and low-velocity flow. Temporary methods can be organic (biodegradable), synthetic (photodegradable), or a mix of the two. 0000004210 00000 n EcoArmour dries … vegetation provides permanent erosion control. Applications range from gradual to steep slopes, and low to high-velocity water flow channels. Turf Reinforcement Mats (TRM) RECPs are divided into temporary and permanent erosion control materials. The high lignin content of the coir helps the pallets to cope with water that is coming at a high velocity, thereby protecting the vegetation against water erosion. 0000003216 00000 n INSTALLATION /A PPLICATION CRITERIA: The mean average rainfall in this district is 2322 mm. Perfect for banks, slopes, hillsides, or channels, these sediment erosion products reinforce surrounding areas to prevent erosion and allow vegetation to take root. Coir erosion control blankets can be easily transported and deployed, and once the biodegradation process starts, the spun and woven coir blanket’s remnants can found in the form of hummus. These mats reduce soil loss and protect vegetation from being washed away or uprooted, even under high stress. 127 0 obj <> endobj The principal hydraulic design parameter is either the allowable flow velocity or allowable shear stress. Ranging from open meshes to dense mats and even hydraulical applications, erosion controls blankets protect vulnerable soil from wind and water erosion.. Turf Reinforcement Mats (TRM) are the ideal product for long term erosion protection on slopes and in channels. However, they can be placed in a narrower right-of-way and … 1.62 lb/yd. 9 m 0000000791 00000 n The Curlex High Velocity blanket comes from seed free Great Lakes Aspen Excelsior Fibers designed to provide extended protection for grass seed and topsoil from wind and water erosion for approximately 36+ months, while simultaneously promoting ideal growing conditions on steep, long slopes and/or in channel applications. An erosion control blanket composed of processed slow degrading natural or polymer fibers mechanically bound together between two slow degrading synthetic or natural fiber nettings to form a continuous matrix or an open weave textile composed of processed slow degrading natural or polymer yarns or twines woven into a continuous matrix. Netting types can be matched to the job site ... staples are typically used in high velocity channel applications. Use approx. Netting types can be matched to the job site requirements. Erosion control blankets are used in place of mulch on areas of high velocity runoff and/or steep grade, to aid in controlling erosion on critical areas by protecting young vegetation. ... Extended-term erosion control blankets have the features of all-natural products but with a longer life cycle. M�l 0000002612 00000 n This may give some indication of the potential for instability.
