Controls Erosion Immediately
HydraCX2 is hydraulically-applied erosion control that protects against soil and seed loss from heavy rain and wind—even before germination; then effectively establishes permanent vegetation.
ASTM D 6459: Standard Test Method for Determination of Erosion Control Blanket (ECB) Performance in Protecting Hillslopes from Rainfall-Induced Erosion
The modification of this test method evaluated the ability of HydraCX2 to protect a slope from rainfall-induced erosion by utilizing full-scale testing procedures rather than bench-scale testing procedures. The full-scale testing procedures were intended to mimic conditions that are typical for final earthwork conditions, but prior to any establishment of vegetation. The test method provided a comparative evaluation of the product to baseline bare-soil conditions under a controlled and documented environment.
An earthen embankment was constructed using conventional earthwork procedures to create a plot surface of 3H:1V that was 40 feet in length and 8 feet in width. Testing was performed for three separate, 20-minute durations at target intensities of 2 inches per hour, 4 inches per hour, and 6 inches per hour, respectively. (Actual intensities in HydraCX2 testing exceeded these target intensities. See table.) A C Factor, or Cover Factor, indicates the product’s performance capabilities, and was calibrated from the test data by comparing the soil loss in a bare-soil scenario to the soil loss in a protected-soil scenario.
