1.   Determine Soil Type

Anchor holding capacity will vary in different soils. Increased capacities can be expected in harder soil classes (numerically higher blow count classifications) and lower capacity can be expected in the softer soil classes (numerically lower blow count). To see our holding capacities chart click here.

There are various ways of testing soils. A torque probe is the best for quick classification in the field. Core samples are best for detailed classification but are expensive and take time to obtain results. Generally resistance to driving the DUCKBILL is a good indicator of soil class. Stiff resistance normally results in positive anchoring. Easy anchor driving may mean the soil is soft and steps should be taken to ensure adequate capacity. Simple anchor-locking will verify the capacity of the anchor in any soil class.

2.   Drive the DUCKBILL anchor to proper depth

Using a hammer and drive steel (a smaller jack hammer can also be used together with power drive steel) drive the DUCKBILL® into the soil. As it is being driven it is actually compacting the soil around the anchor head. Once anchor is at proper depth, the drive steel is removed.

3.   Set the DUCKBILL anchor in soil

To set the anchor in normal soil, wrap the wire rope around the drive steel or insert rod through the loop in wire rope and pull upward a distance approximately the length of the anchor body. Or use the DUCKBILL Anchor Hook. The upward pull on the wire rope rotates the anchor into a perpendicular load lock position in undisturbed soil.

4.   Lock anchor into position

When you pull on the cable, the anchor locks into position like a toggle bolt. As you pull harder, the anchor will compact the soil, thus increasing the holding strength.
