Williams Form Engineering markets a product line called Manta Ray Earth Anchor Systems. The low capacity anchors (range of 0.2 - 20 kips) involve the use of a small plate at the end of a rod and can be installed with a jackhammer along with some special equipment which can be rented or purchased from Williams. The manufacturer's literature provides approximate holding capacities and embedment depths which are correlated with blow counts and soil type. Equipment is available to test the actual capacity in the field. The phone number for Williams Form Engineering is 616-365-9220. The phone number for the manufacturer of the system (Foresight) is 800-325-5360.

Basically these would be steel stakes driven into the ground to anchor a building or canopy. Specifically, they will hold down a steel carport structure. The soil nails, "stakes", are driven about 24-30 inches into the ground. The deformed bars (rebar?) are threaded at the top so that a nut can be installed to hold down a base channel. I am not aware of any guidelines on their use, have never seen any testing or engineering data. There are no catalogs listing these and their capacities. Does anyone on this list have any suggestions on how to evaluate these anchors? Is this all done by "feel" alone? Does the installer just monitor how far his hammer will drive the anchor per blow and apply some driving resistance factor? I am at a loss. Any suggestions would be appreciated. The loading on these small structures is due to 70 mph winds, no seismic to speak of. Roof loads of 20 psf.
