What is a case foundation?

Case foundations are a type of deep foundation used in construction to support structures where surface soils lack sufficient bearing capacity. They typically involve drilling a hole into the ground and filling it with reinforced concrete to create a stable base for buildings, bridges, or other heavy structures. This method is especially common in large commercial or infrastructure projects where standard shallow foundations would not provide adequate support. Case foundations ensure the load of the structure is transferred to deeper, more stable soil or rock layers, enhancing safety and longevity.
