Types of Foundation
There are two types of foundations: deep & shallow foundation) which are used for building the constructions such as homes, buildings, roads, etc. Usually, the choice criteria for such foundation also depend upon the soil condition and load for the structure to be supported. There are many foundations that are widely used for different purposes. Let’s take a quick look at them.
Most of the people think that poured concrete walls are the only type of foundation available for commercial purpose. Actually, there are several types of foundations which can be installed for different purposes. Foundations such as poured concrete walls do not require any additional work from the builders or owners. Other foundations, such as concrete slabs, steel walls and steel flooring, require additional work from the builders or owners. In case of steel flooring or concrete masonry units, the foundation contractors provide the materials for the walls and these too need to be installed by them.
Also called as slab foundations, these types of foundations are commonly used in colder climates. The slab foundation is made by putting earth on the base of the structure and then filling the ends with concrete. The foundation of a house is mostly made up of such a type of foundation. The slab’s thickness usually ranges between six and eight inches.
The footing, also known as dynamic foundation, is another type of foundation. In case of a normal house structure, the footings or the ground support system to provide the required weight stability to the structure, but for houses which are in extreme climates, the footing becomes the burden. The footing is a type of load-bearing wall. A typical example of such a wall is a slab. A foundation supports a slab and prevents slabs from sliding down.
As mentioned above, the slab foundation is the most popular one among the rest. It doesn’t require as much work as wooden foundations. It is also easier to build and maintain than the wooden ones. The only thing that is required here is to make sure that there is no contact between the slabs and the ground. In order to achieve this, the concrete is poured into the holes and spread using spas and pumps. Wood foundations require the foundation to be deeper.
The concrete is then placed on top of it and forms a level surface. All types of house foundations have the following three basic elements: load-bearing walls (the footing), protective barriers (structural wall or beams) and soil conditions. Load-bearing walls are required to bear the weight of the soil. For wooden foundations, these are usually made of cement blocks or bricks. The load-bearing walls usually run parallel to the slope or gradient of the soil.
The combined footing and pervious footings are the next two types. A combined footing is made up of several layers of soil that are separated by a permeable gravel layer. The permeable layer made of gravels conducts water away from the house and keeps it outside. A pervious footing is made up of soil and sand. The soil’s moisture is retained by the pervious layer.
These are just two main types of foundation. You can also learn more about other foundation types by researching the load-bearing walls of your house and the permeable nature your soil. There are many other factors that you should consider when it comes down to foundations. However, these two main types should help you decide which of them would be the best for your house. Be aware that you must have a foundation in place before you begin building.
