HydraMatriCx Delivers Successful Performance in AASHTO's NTPEP Testing

North American Green’s HydraMatriCx hydraulically-applied erosion control products have posted the best results ever published to date in large-scale slope protection tests by the American Association of State Highway Transportation Officials National Transportation Product Evaluation Program (AASHTO-NTPEP), the company said. HydraCX2 Extreme Slope Matrix demonstrated 100% soil protection, and HydraCM Steep Slope Matrix registered 99.7% effectiveness in reducing soil erosion.

“HydraCX2 Extreme Slope Matrix is the first and only HECP in the industry to demonstrate no measurable soil loss in NTPEP large-scale slope testing,” said North American Green’s president, Tim Lancaster. “The ASTM D6459 large-scale test employed by NTPEP, originally designed for testing rolled erosion control products but modified to accommodate HECPs, utilizes rainfall intensities up to 6 in. per hour and really taxes the performance capabilities of an erosion control material.

“In fact, it’s easy to see that HECPs can suffer catastrophic failures when tested under this grueling protocol. The results demonstrated by both the HydraCX2 and HydraCM products are truly incredible for HECPs, or any erosion control materials for that matter. Furthermore, both products have excellent vegetation establishment capabilities, so they not only lock down soil immediately, but ensure long-term erosion and sediment control by quickly establishing a dense vegetative stand.”

HydraCX2 Extreme Slope Matrix registered no measurable soil loss or erosion during testing. HydraCM Steep Slope Matrix also posted successful results, with two of its three plots experiencing no measurable erosion, while the third plot experienced only minimal localized soil loss, the company said.

“The NTPEP test results quantitatively suggest that North American Green’s HydraMatriCx Series of mulches can deliver greater erosion control performance than even our single and double net erosion control blankets,” said North American Green manager of engineering and business development, Gabe Weaver. “We feel these results illustrate the products' exceptional performance capabilities and further support our confidence in delivering high performing, reliable and cost-effective products for erosion protection and sediment control.”
