If you want the most secure and cost-effective method of anchoring movable soccer goals you’ll want to consider using Duckbill anchors.
There are many ways to anchor movable soccer goals; driven stakes, anchor weights, j-hooks, sandbags, concrete footings, etc. … All these methods of anchoring help soccer goals become more secure if used properly, especially when compared to a soccer goal with no anchors at all. However, each has drawbacks.
“If normal soil conditions exist, we feel the Duckbill anchor is the most effective way of anchoring a movable soccer goal” said Chris Bielefeld, Structural Engineer at Keeper Goals.
A Duckbill anchor is a small metal anchor attached to the end of a galvanized wire rope. It is driven into the ground using a hammer and a steel driver rod (no holes, no digging and no concrete is required). By applying an upward pull on the wire rope, the Duckbill anchor rotates into a perpendicular position in the soil. The result is an extremely strong anchor. Typically a chain and lock are attached to the free end of the wire rope to attach to and secure the goal. Plastic ground sleeves may be purchased separately to allow for the chain and lock to be stored and protected below the ground surface. When a goal needs to be moved, the chain and lock can be easily removed and stored, whereas, driven stakes or j-hooks could be difficult to remove and will need to be stored separately.
Duckbill anchors can sometimes be difficult to drive into the ground, no different than any other driven anchor or stake. Duckbill anchors are safer than traditional stakes or anchors because they leave no rigid rods or stakes above ground that could cause injury.
Stake and j-hook style anchors could pull out very easily when installed in very wet or very dry soil. Per the manufacturer, a Duckbill anchor has a specified rated capacity, whereas, driven stakes and j-hooks do not. A rated capacity provides a stated value of uplift resistance when installed in normal soil conditions. The uplift resistance of driven stake and j-hook style anchors cannot be quantified without testing them in the soil at the actual goal location.
