to be constructed after they have been driven into the soil a small portion of each pile remains above the ground level but the height or level of the remaining tops of the piles are not even as mentioned before along the lines connecting the piles according to the designed layout trenches are dug and rubble and gravel are placed in the trenches and leveled so as to form the bed for the footing the bed may be solidified by adding mortar or cement milk leveling elements such as shown in fig1 for instance are placed so that their apertures receive the top of the piles and are oriented so that the indentations are aligned fig2 shows a leveling element 2 placed on the bed 3 so that the top of a pile 1 extends upward through the aperture 24 usually it is impossible to make the centers of all the piles exactly accord with the designed center lines of the continuous footing as mentioned above however the cross section diameter of the aperture in the leveling block is considerably larger than the cross section diameter of the piles therefore the leveling elements can be placed exactly on the designed footing lines thus the continuous.
