Advantages And Disadvantages Of Strip Foundation Like any other type of foundation, strip footing also has some advantages and disadvantages. Advantages of a prefabricated foundation: The base, which is erected by assembling prefabricated slabs, is ideal for low-rise buildings. Deep foundations are necessary where the bearing capacity of the surface soils is not adequate to support the loads imposed by a structure and so they need to be transferred to deeper layers with higher bearing capacity. A deep foundation is a type of foundation that transfers building loads to the earth farther down than a shallow foundation does to a subsurface layer or a range of depths, the function of deep foundations is to transmit the weight of the building to the firm layers deep inside the ground. To determine the overall dimensions of the block, its volume and mass, the value of which must be taken into account when choosing lifting equipment, is determined from its marking. They are briefly described as follows: Pre-cast concrete piles are one of the most commonly used pile foundations. If we are talking about a shed or garage, then you can not add additional flooring, but use the surface of the foundation as a floor.
