Another arrangement of piles to reduce differential settlement is by changing the geometry of the piles. For perimeter area, piles with soft toes or short expanded base piles can be used and long straight shafted pile can be considered for the central region of the slab. Soft toe can be obtained by placing loose sand or soil at the base of bore hole prior to the pouring of concrete.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
