The design of many engineering structures requires foundation systems to resist vertical uplift or horizontal pull-out forces. In such cases, an attractive and economic design solution may be achieved through the use of tension members. These members, which are referred to as soil anchors, are typically fixed to the structure and embedded in the ground to sufficient depth that they can resist pull-out forces with safety. Soil or 'ground' anchors are a lightweight foundation system designed and constructed specifically to resist any uplifting force or overturning moment placed on a structure.
