If you are planning to build a home, the foundation is one of the most important aspects to consider. Good foundations and the best construction materials will enable your home to withstand the elements for a very long time. There are five types of foundations available.
A raft foundation is the simplest type of foundation, consisting of a single raft of concrete. A raft foundation is commonly built by filling up a wooden frame or a concrete block to create a concrete base for the house. Since the foundation is only a single layer of concrete slab, there is no room underneath the foundation for first fix work. A raft foundation is best for smaller structures like sheds and storage rooms.
Raft foundations are also more appropriate in areas where the soil is loose and sandy; this type of foundation could also be fit areas that are waterlogged.
Strip foundation is another durable type of foundation. This is actually the most common foundation and is primarily used in areas where the base has a strong soil and in areas that is non-waterlogged.
In this type, concrete blocks or frames are built along the outer perimeter of the infrastructure that is thicker than the actual walls of the house. The weight of the house is spread over the foundation to make it more stable.
A piled foundation is a form of deep foundation made using a hollowed block or poured concrete with piles, and supporting walls at the centre of the house, to provide support. This is actually the most expensive type of foundation yet it is considered the strongest. Most geotechnical engineers recommend deep foundations because they add support in poor soil and for larger buildings.
A crawlspace provides an extra space between the floor and the ground that is tall enough to allow a person to crawl within it. Crawlspaces allow technicians to install air conditioning units and wiring projects beneath the floor. One of the advantages of this type of foundation is it places the house in a higher ground, preventing the foundation from becoming damp or from being infested with termites. It is costs less.
A basement is a space between the floor and the ground that is large enough for a person to stand in. Some homeowners may transform a large basement to create additional family rooms.
The type of foundation that you need will depend on what you have to build. Nevertheless, deep foundations are preferred to allow better support for the house.
