Functional longevity is a term describing how long an erosion control material is predicted to provide desired performance attributes. Actual functional longevity is determined by a material’s physical composition as well as site-specific conditions such as temperature, moisture, sunlight, soil composition, biological activity and other environmental factors.

The ASTM D5338 protocol confirms Flexterra HP-FGM’s observed functional longevity of up to 18 months. As illustrated in the test results presented on the right, Flexterra® HP-FGM™ is proven to last longer than other hydraulically applied erosion control products. 

Long-lasting Flexterra HP-FGM is designed to:

• Provide protection on bare soil over periods of dormancy, such as winter or extended dry periods, when seed germination is not possible; yet soil erosion and seed washout can occur from snow melt and runoff.
  • Flexterra HP-FGM assures that when more optimal growing conditions arrive, the seed and nutrients are still in place and in an environment conducive to germination and emergence.
• Ensure sustainability of plants
  • Emerging seedlings need moisture and nutrients near the surface. The exceptional absorptive properties of Flexterra HP-FGM nurture vegetation to better withstand environmental stress.
• Accommodate a broad range of vegetative species
  • Seed from native and forage grasses, fine turf, shrubs, forbs and other types of vegetation have different germination and establishment requirements. Flexterra HP-FGM protects and helps to cultivate even the slowest developing species.
