The foundation (1) comprises an inner tube (2) and outer tube (3) separated by a gap (5), in addition to a foundation plate (4) placed on top of the upper ends of the two tubes. The column is securable to the foundation plate. The inner tube can be pressed into the tube and the gap between the tubes can then be filled with concrete. The length of the outer tube is less than that of the inner tube. |
