The concrete solution should meet the requirements of compatibility with the soil chemicals. The different types of shallow foundation are: A strip footing is provided for a load-bearing wall. The floating foundation tends to move along with the movements of the ground and, thus, the load on the walls is weakened. Disadvantages of Starting a Private Foundation. Sometimes, Brick flat soling is made instead of PCC. If a building has several columns with high localized loads this footing may not be appropriate.

When erecting a foundation on solid ground, it can be the same width as the walls, so the trench needs to be expanded only by the thickness of the formwork boards. As mentioned above, the foundation is the main part of the structure and therefore, how strong and durable the building will be depends on how the type of foundation is chosen correctly, how accurately the soil analysis is carried out, and, of course, the quality of the foundation itself. The type of foundation whose depth is more than that of width is known as a deep foundation. They are briefly described as follows: Pre-cast concrete piles are one of the most commonly used pile foundations. 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. The advantages of raft foundation are as follows: Raft foundations are constructed for shallow depths hence, it requires less excavation. Any and all calculations you require should be carried out by registered, experienced engineers and only after local soil testing and load bearing requirements have been established.
