TYPICAL FIELD FOUNDATIONS

SEPLA• Combines advantages of suction embedment and proven plate anchor

technology (Developed by U.S. Navy During 80’s)

• Uses suction embedment follower with plate anchor slotted into base to install plate anchor

• Follower is then removed by reversing pump action, leaving plate at depth

• Plate is then rotated to orientation close to perpendicular to direction of load

• Geotechnically efficient shape

Shallow Foundations Used For Light Loads
