Foundation on Made-up or Reclaimed Ground
Sometimes, low lying areas or previously excavated areas are filled by dumping debris, refused and excavated soil. This type of fillup land is known as made-up ground or reclaimed ground. Such grounds have some unreliable and peculiar properties.
It should be remembered that reclaimed grounds are not properly consolidated, and also the bearing capacity of such soil does not remain constant. So, before starting construction on such lands, their peculiar properties should be carefully considered. Otherwise, it may cause damage to the structure.
In founding structure on the made-up ground or reclaimed ground following precautions should be considered:
1. If small pockets are found on the reclaimed ground or made-up ground, they should be cleared and replaced with good-quality soil
2. If the load of the structure which is to be constructed on such lands is not too heavy, the raft foundation will be the best choice. But, if the load of the structure is too heavy and unevenly distributed, a pile foundation should be considered.
