How much deeper should holes for poles be set in angles, corners, or marshes than a standard hole?

Setting poles in angles, corners, or marshes requires deeper holes than standard ones due to several factors. The correct choice reflects the need for additional stability and support in these more challenging locations.

In these areas, conditions can vary significantly from standard installation sites, often resulting in less soil holding power or more potential for movement of the poles due to environmental factors like water saturation or shifting ground. Thus, increasing the depth by 6 inches provides added anchoring, which helps ensure that the poles remain upright and secure even when subjected to additional stresses that are common in marshy or irregular ground conditions.

Furthermore, this depth adjustment helps to counteract the potential for soil erosion around the base of a pole, enhancing its longevity and effectiveness in holding up structures such as fences or signage in areas that might experience frequent changes in moisture levels or ground stability.
