FoundationsFoundations in building and construction are the part which gets into contact with the ground and the main role these foundations play is to transmit the whole load of the building to the ground this is done in a way that settlement is limited and failure of the underlying soil is avoided. Foundations are classified in two types, either shallow foundations or deep foundation. The types of foundations too be used also is dependant on several factors, these being: - Influence such as water tables and gravel contours. - Size of building; - Type of soil; - Size of building; - Influence such as water tables and gravel contours. Strip foundationStrip foundations are mostly used for domestic building, these types of foundations are used to support a line of loads; this can be due to a load-bearing wall and it can also be when a line of columns need supporting. Trench FillThis is highly used in areas where there is a high water table; it can also be used in areas where there are trees being grown near the building area.
This may result to the ground soil being loose thus the foundation type is recommended. Raft FoundationThese types of foundations are usually used on the grounds where there is a soft soil that is the soils that are loose and with low bearing capacity; the reason why it is recommended for these types of soils is that they can spread the loads over a larger area.
