Types and Benefits of Combined Footing
Combined Footing
Combined Footing refers to several columns in a straight line that spreads out over a single spread footing. When two columns are close together, the soil bearing capacity is lower and the combined footing use is higher. It is better to provide a combined footing than separate isolated footings when two columns are close together. The cost of isolated footings is typically lower.
When you use Combined Footing
Combination footings can take the shapes of rectangles, trapezoids. It is ultimately necessary to achieve uniform pressure distribution under the entire footing area. It is best to align the center of gravity of the footing area with that of the total load of two or more columns.
