G-Weave Fabric Developments
• Gunderboom Testing and Results– Tensile Strength – 440 vs. > 1400 lbs.*
– Sew Seam Strength – ½” from edge
– Pressure Wash Durability – No Signs of Wear
– Agitation – No Signs of Wear; Heat Welds Held Up
– Rip Stop – 200 vs. 1150 lbs.*
– Puncture Durability – No Resultant Tearing
*Traditional Non-Woven vs. G-Weave Woven
G-Weave Fabric Developments
Biological Survivability – Testing at Alden Labs
Survival of Blueback Herring eggs after exposure to the G-Weave fabric in the laboratory was high
Alden described that, “the mortality experienced in this study... may potentially reflect natural mortality”.
There was no significant difference between the survival of eggs exposed to the new G-Weave fabric, or other Gunderboom fabrics, and the control samples.

“Conclusion -Calculation of ichthyoplankton exclusion rate based on seasonal
paired plankton sampling and analysis yielded a 95.4% exclusion for fish larvae and 96.4% exclusion for fish eggs.”

HEAVY DUTY TURBIDITY BARRIERSpecification:
“A. Silt/turbidity barrier shall consist of heavy duty non-woven skirt, flotation elements, PVC coated
reinforced vinyl debris boom, top tension cable and bottom chain ballast or other anchorage system which
will not obstruct navigation.B. Barrier shall be full-height, extending from the water surface to the river bottom. The height will depend on the alignment of turbidity barrier and the bathymetric
contours along that alignment.C. Non-woven skirt shall be comprised of 100%
polypropylene filaments, needle punched and heat set.”
