The design involves laterally braced columns piercing through weaker soil and reaching the suitable ground. The lateral loading receives resistance in the pile foundation through bending. The use of pile foundations is appropriate for areas that do not have sufficient land for construction, or the ground is soft. Therefore, you can notice clearly that there are differences between the raft and pile foundations. The most prominent point of different lies in the types of buildings for which they are suitable.
Both types of foundation are distinct in terms of design and offer different cost benefits also. For example, raft foundations prove cost-effective in the short-term while pile foundations are built for the long journey! News Home News.

The slab is spread out under the entire building or at least a large part of it which lowers the contact pressure compared to the traditionally used strip or trench footings.
What are types of piles? This method is practically suitable for all type of ground condition. What is raft foundation and their types? Raft foundation is a thick reinforced concrete slab which spreads over a large area of soil and provides support for several columns and load bearing walls.
