ECMDS® 5.0 ensures the proper evaluation and design for soil-loss prediction,product specification and project planning.

“All recommendations within the latest version of ECMDS® are based on data Tensar has collected from controlled laboratory and field research involving erosion control blankets, turf reinforcement mats,vegetation establishment, hydraulic mulches, sediment control devices, and transitioning devices,” said Tim Lancaster, Director of Erosion Control and Marine Technology at Tensar International.

“Tensar’s ECMDS® 5.0 testing has been conducted by reputable organizations like the American Association of State Highway Officials’ National Transportation Product Evaluation Program (AASHTO-NTPEP),Texas Transportation Institute (TTI), San Diego State University, and Colorado State University, among others,” Lancaster continued. “Tensar is proud to exceed the standards and regulations set forth by the Erosion Control Technology Council (ECTC), ASTM International and Environmental Protection Agency (EPA). Engineers, designers and contractors can quickly and easily design highly cost-effective erosion protection for their projects to comply with today’s strict erosion and sediment control regulations when utilizing our design software.”

“Providing our software in a web-based application helps to better serve Tensar’s end-users,” said Gabe Weaver, Manager of Engineering and Business Development at Tensar International. “In today’s world of portable handheld devices, Tensar’s software registrants now have access to design projects from their smart phones, notebooks or anything with an Internet connection. Our registrants are not limited simply to a desktop computer or CD-ROM disc. The application offers robust calculations to develop cost-effective,sustainable erosion control and vegetation establishment with both rolled erosion control products (RECPs) and hydraulic erosion control products(HECPs). It also features dynamic graphics throughout its various analysis pages.”

ECMDS® 5.0 provides valuable insight for anyspecifier or engineer by providing comprehensive analysis for site-specificconditions, ranging from channel and slope protection to new features includingtransition mats and drop structure designs.
