The BIO-ANCHOR Tested
As more products emerge for the Erosion Control Industry, claims by manufacturers
must be tested and proved. Good Lab Practices, repeatability and standard
methods are required to substantiate claims in advertising.
The BIO-ANCHOR was tested under such parameters to quantify the force required to remove the unit from standard test pots. These tests were run on other types of blanket fasteners and the results are compared below.
- 200 mm diameter x 150 mm deep pots were filled with silty sand compacted
to 90±3%of Standard Proctor density, at a soil moisture within ±3% of
optimum moisture content ASTM D-698.
- A single anchor was machine “forced” vertically down into the soil to
the prescribed depth at a rate of 2 inches per minute. The Bio-Anchor
was pushed to the prescribed depth of 2.5 inches and the metal staple
to a prescribed depth of 6 inches.
- After one minute, the anchor was “extracted” vertically upward at a
rate of 2 inches per minute while measuring/recording the force required.
- Each test was conducted on freshly prepared cores.
The index anchorage tests were performed using the following protocol:
These tests show that the 3" BIO-ANCHOR holds more than twice as better than a six-inch, eleven gauge wire staple, 30% better than an eight inch, eight gauge wire staple, and 10% better than a 4" single leg product.
