Pile Caps

The depth of the pile cap should be enough for anchoring the column reinforcement as well as that of the pile. The pile should project 50 mm within the concrete of the cap. The cap should be rigid sufficient to distribute the load to the pile and to take care of differential settlements, if any. The overhang of the pile cap beyond the outer pile is of the order of 100 to 150 mm. The cap is commonly cast over a 75 mm thick bed of leveling concrete. A clear cover of 60 mm is given for the major reinforcement.
