Click ‘Calculate’ to see the total volume of concrete and the number of concrete bags required. Design of post-installed reinforcing bar connections requires that the type, size, spacing and quantity be established for the connection. In some cases, the grout within the post pocket just simply weathers or turns to rubble (Figure 6). Simply provide the dimensions of the post holes and the coverage per cement bag, and click “Calculate”. Inadequately sized footings can lead to uneven settlement, structural instability, or permit rejection. Calculate Total Concrete for All Posts Total concrete = 0. The concrete base will be core drilled, the steel pipe post inserted into this void, and the gap between pipe and concrete filled with non-shrink grout with a higher f'c than the concrete, which has a f'c=4000psi. The depth of embedment is the main design parameter for these pole foundations.
