If the depth of the excavation is below the water table then dewatering is essential. The walls of excavated part should be supported using sheet piles or timber piles or soldier piles etc. The excavation for floating foundation should be done carefully. Here also, floating foundation helps to reduce the shear stresses to satisfactory level and hence settlement is prevented.ĭifficulties in Construction of Floating Foundationĭuring the construction of floating foundation some problems may arise which can be prevented by taking proper care.
