When horizontal space is limited, the shallow vertical groundbed is the most effective choice. This type of groundbed accommodates situations where the lateral area available for installation is restricted, allowing engineers to utilize vertical space instead. By employing a vertical configuration, multiple ground rods can be placed in a narrow footprint.

This method maximizes the surface area in contact with the soil and increases the grounding system's effectiveness, especially in areas where water tables or soil conditions necessitate deeper installation. In cases where conventional or distributed anode groundbeds are impractical due to space constraints, the shallow vertical groundbed provides a practical solution.

Furthermore, the design of a shallow vertical groundbed can lead to reduced costs and simplified installation compared to digging extensive horizontal trenches or excavating larger areas necessary for other types of groundbeds.
