Ground Anchor 3 x 63 x 0.14in (for 2" SGA) Installation

Installation Instruction Manual

For

ICC ES AC 443

Pre-Installation

• Know your soil composition: If you don’t take time to determine your soil composition

you must use the minimum allowable loads for the particular screw you are using when

planning your structure. Determine as cohesive (high clay) vs. non-cohesive (low clay or

high sand) to determine load capacity as listed in the relevant section of the ICC-ES

report. By code a complete Geotech report and engineer certification is required.

• Safety equipment/PPE: Use adequate safety equipment while mechanically installing

ground screws, i.e., steel toe shoes, safety glasses, gloves, hard hat, etc.

• Dial 811 call before you dig to ensure a clear path from utilities for the screw to

penetrate into the subsurface.

• Be sure of above ground clearance of obstructions and nonessential personnel.

• Locate your desired screw positions with flags.

• Pilot holes to improve accuracy are helpful for very hard soil, but not necessary. If you

choose to do so, predrill with a 1/3 diameter by 1/3 deep wood bit, or drive a rod or

stake into the ground as plumb as possible. You will still need to use a level during

installation to maintain plumb. Adjustments to level can still be achieved through the

initial 2/3

depth of installation.

Installation

• The product may be used as a foundation system to support various constructions,

provided that it is installed according to the manufacturer's current instructions and

within the scope

of ICC ES AC443. Wood and metal framing preferred.

• Follow safe handling instructions laid out by the mechanized driver manufacturer

• Confirm that the adapter connecting the drive shaft of the mechanical driver to the

screw that is being installed lines up and seats properly.

• If using a Model 3 (open top with 3 welded nuts) ground screw, install the bolts so

they are flush with the inside of the ground screw before installation to help

maintain the integrity of the nut during installation.

• If using a screw with a pre welded flange, make sure that the flange face and adapter

face match and are bolted tight prior to attempting the install.

• • Ground screws must be installed in a clockwise rotation and uninstalled in a counter clockwise rotation. During installation the rotation of the ground screw must be accompanied with appropriate downward pressure (crowd) to advance the screw one thread pitch per rotation. For example, the thread pitch is 40mm (1 1/2-1 5/8”) on all ICC approved ground screws. Therefore, the screw should advance downward approximately 40mm or 1 1/2-1 5/8” per rotation.

Should churning or augering occur without immediate correction, the screw should be removed and repositioned. If using the same hole is required, 3/8” “chip” gravel can be poured into the hole to re-establish the load-ability following the installation procedures described above. A maximum of 15 RPMs is advised and only with a mechanical driver capable of enough crowd to advance the screw as described above. • • • Rotation must be used during installation.
