Information About Concrete Foundation And Its Different Types

Foundations are an architectural structure element which connects and transfers the structure loads to the ground. They are generally considered as either shallow or deep and soil and rock mechanics are applied in designing them. Shallow foundations will be used to support small and light buildings and the deep ones support large and heavy structures.

Shallow ones are called spread as well as open footings also because they are made by excavating the earth first till its bottom which makes them visible during construction. Then ideally, each footing of Kennebunk concrete foundation will take the entire load from the column then spreads it to a huge area. This prevents the definite weight on soil to exceed its safe bearing capacity.

These foundations should be protected from freezing in cold climates because the surrounding water would freeze and expand damaging them. They must be build beneath ground level that freezing occurs or the frost line. If this is not possible then an insulation must protect them that is the little heat permeating into the ground from that building to prevent freezing.

Shallow footings have several types and one of them is individual footings which the columns carry the building load. Every column has their own footing which is either a square or rectangular tablet of concrete that it sits on. The size pads are dependent on the load. The columns are usually connected by horizontal plinth beam together and is built either below or at the ground level.

Another example is strip footings which are common in masonry constructions that bears load acting as long strips supporting the weight. These are for the time when walls are used in carrying building loads rather than separated columns. Small strip of concrete is placed into a trench and steel is used to reinforce them.

Another one are raft foundations commonly used when basements would be constructed and the floor slabs will act as its foundation. Building weight is spread evenly over the entire footprint which looks like a structure floating in soil hence naming it raft. They are used if the ground is weak so it can spread the load on large area.

Pile foundations are long cylinders of strong materials like concrete which is pushed in the ground to support the structures on top. The following conditions are the basis of when to use them with the first being when the soil is weak and bypassing this layer is needed because it is unable to support the weight. Another is for concentrated heavy loads of high rise structures.

These have two types and end bearing pile is one where its bottom rest on specially strong layer of soil and rock. The piles act like columns by transferring the load through it in to the strong layer and bypasses the weak one. Its key principle is its resting on the weaker and stronger surface layer intersection.

Another one are friction piles where friction is used in transferring the entire weight across the full height. This can support more if it has greater buried depth. The weight it could support is proportional directly to the length.
