Erosion Control Solutions CONTECH Silt Fence Controls Sediment NPDES Regulations Require Immediate Action Uncontrolled silt deposits owing from unprotected construction sites can create health, safety and environmental problems. Recent regulations, covering virtually every construction site today, mandate runoffrelated sediment control. The building boom of the past 25 years has increased stormwater runoff volumes and peak ows. The direct result of this growth are the requirements of the National Pollutant Discharge Elimination Systems Act (NPDES) that mandates that stormwater runoff be controlled to reduce damage to municipal sewers and waterways. CONTECH Silt Fence is a site-proven, effective and economical method to control runoff-carried sediment. Silt CONTECH Silt Fence helps maintain overland sheet ow and lters out Fence offers a combination of suspended soil particles, preventing downstream deposition and acting as UV resistance, strength and a defensive erosion control practice. hydraulic properties to make them idea for use in aboveground sediment control CONTECH Offers a Variety of Other applications. Stormwater doesn’t just runoff. It carries pollutants, sediment and debris, contaminating the drainage system—which empties into streams, lakes and rivers, degrading water quality. Stormwater management issues are nationwide, and with the implementation of Phase II of NPDES, the issues will surface on nearly every construction site. Operators affected by Phase II are required to implement stormwater discharge management controls known as “Best Management Practices” or BMPs. Temporary and permanent erosion control solutions are recognized BMPs. CONTECH Construction Products Inc. provides cost-effective solutions to soil erosion and sediment control problems. Erosion Control Solutions Synthetic Engineering Solutions with Geotextiles CONTECH offers the broadest range of high-quality geosynthetics available: woven and non-woven. CONTECH Geotextiles, with their high strength and dened ltration qualities, have a solid history of long-term performance in applications involving separation, ltration, drainage and erosion control. Woven Geotextiles Woven geotextiles are generally preferred for applications that need high strength properties, have less critical ltration requirements and do not require planar ow. Since woven textiles, on a unit weight basis, achieve higher strengths at lower elongations than non-woven geotextiles, they are extremely efcient in strength priority applications. Non-Woven Geotextiles Non-woven geotextiles are needle-punched, continuous lament engineering fabrics that provide ltration and planar ow, reduce hydrostatic pressure and prevent subsoil migration. Typical applications include subsurface drainage systems, roadway separation, hard armor underlayment and asphalt overlays. Erosion Control Solutions Hard Armor Solutions for Channels, Streams and Shoreline Applications The Armortec® family of products (including ArmorFlex®, A-Jacks®, ArmorWedge™ and ArmorLoc®) can be used to protect against erosion and scour in the most severe hydraulic conditions. Modular Welded Wire Gabions for Erosion Control and Bank Stabilization Modular Welded Wire Gabions are fabricated from steel wire mesh assembled into rectangular cells of varing size. They are lled with stone to form a monolithic, exible structure which provides low cost, long-term erosion control and soil stabilization. Cellular Connement Systems Create an Erosion Barrier Cellular Connement Systems employ a exible HDPE matrix lled with native granular materials to create an erosion barrier. These systems have been proven on a variety of construction, architectural, landscaping, and erosion control situations. ©2009 CONTECH Construction Products Inc. 800.338.1122 www.contech-cpi.com CONTECH Construction Products Inc. provides site solutions for the civil engineering industry.
