Pile Foundation Using Under Reamed Method
Under reamed piles are bored concrete piles having more than one number of bulbs formed by enlarging the pile stem. These piles are best suitable in soils where considerable ground movements occur due to seasonal changes, filled up grounds and soft soil. Its main advantage is increasing the bearing and uplift capacities. It also provides better anchorage length at greater depths. These piles are effectively used in over bridges, machine foundations, electrical transmission tower foundation and sand water tanks.
