GeoHay.com

TRI/Environmental, Inc. of Austin, Texas completed testing four configurations of GeoHay in comparison with major competitor’s products. Results from “testing procedure number ASTM D 5141” clearly indicate that GeoHay products significantly outperform the other major erosion control products where it counts in Filter Efficiency and Turbidity Reduction.

An additional point to be made is that Silt Fence, if installed properly will remove a significant amount of the larger particles as indicated in the Filter Efficiency but is rather poor in Turbidity Reduction which is an indication of total particle removal.

GeoHay has shown capable of reuse, several times, making it not only the best performing erosion control boundary control product, but also the most cost effective.
