Soil anchors are primarily designed and constructed to resist outwardly-directed loads imposed on the foundation of a structure. These outwardly Ð directed loads are transmitted to the soil at a greater depth by the soil anchors. Buried anchors have been used for thousands of years to stabilize structures.
In general at the present time, anchors placed in soil can be derived into six basic categories: anchor plates, direct embedment anchors, helical anchors, grouted anchors, anchor piles, drilled shafts and soil hook systems. The new form of soil anchor used for resisting vertically directed uplifting loads is Soil Hook System (SHS) that can be installed without excavating and grout to the required depth in the ground.
