Concrete Foundations are used for all buildings to make sure they are able to be erected upon. Houses, commercial structures, and pretty much everything else in between are all constructed upon concrete foundations. Concrete has always been used as a basis for foundations for more than a century, long before architects realized how versatile it could really be for structures.
The most common type of concrete foundations are slab-on-grade foundations. This type of foundation allows for flexibility in shape because the concrete slabs are stacked on a straight column that forms a shallow base on which the foundation’s weight is applied. The slab-on-grade foundation is commonly made out of expanded polystyrene, expanded polycarbonate, or polyethylene. These materials are mixed together using a catalyst and then poured to form a concrete slab.
Other types of concrete foundations include post-tension and poured concrete foundations. Post-tension foundation allows for tensioned concrete that is poured directly onto the earth’s surface, while pouring concrete foundations are poured onto precast walls that are then bolted to the earth for additional strength. Both of these types of foundations have their advantages and disadvantages. Poured concrete foundations can actually be poured right onto a parking lot, garage, or other open area where a home or business may be located. Post-tension foundations must be poured into a reinforced hole in the ground or on a foundation sloped to a yard.
A concrete foundation comes in several different varieties, depending upon the application. A very popular type of foundation is the slip-site foundation. These types of concrete foundations are usually installed on low-sloping sites because this prevents soil water from eroding and moving to the base. Slip-site foundations should also be constructed with the drainage necessary to avoid subsidence due to runoff from parking areas or streets.
Concrete foundations come in two forms: vertical and horizontal. Horizontal foundations are created by digging a hole and filling it with gravel; then installing wooden piles at each end. The depth of the holes can vary, depending on local conditions and construction requirements. Vertical foundations use vertical wooden piles that are arranged in an X pattern to hold up the concrete. Because of the way the piles are set, they tend to be sturdier and usually require fewer layers of wooden piles.
There are a few different ways to install concrete foundations. You can purchase a kit and have the site graded and prepared; then once the site is ready, you can pour the concrete. Another option is to purchase a slab-on-grade foundation. With slab-on-grade foundations, the ground is excavated, slabs are poured, and footings are set on top of the excavated ground. Most concrete foundations require concrete footings of a certain thickness and width to adhere to the surface and prevent sinking.
Concrete footings are another type of foundation. They’re typically circular and allow for movement between the layers of slabs. If you have a lot of precipitation, you might want to consider using t-shaped footings. T-shaped footings are used in wet clay soils where movement between layers is less likely.
These three types of foundations are the most common. The others include concrete blocks, poured concrete, and slab-on-grade foundations. All three types have their advantages and disadvantages. Slab-on-grade foundations and poured concrete are by far the least expensive. In addition, these types have the most flexibility when it comes to site design and construction.
Concrete block foundations are constructed using two parallel rows of concrete. One row is directly below the other, while retaining the top row of concrete for covering and stabilization. Concrete slab-on-grout is poured directly over the first row of concrete and is then covered with concrete grout.
slab-on-grade foundations are built on a concrete slab. There are three types of concrete foundations. These are straight, curved, and free-standing concrete foundations.
Straight and curved concrete foundations are the easiest to construct. The first layer of stone or earth is set in the upward direction, and slabs of poured concrete are set below the first layer, all forming a right angle. For free-standing foundations, two slabs of poured concrete are set in the upward direction, slabs are set on each side of the first layer, and then the concrete foundation is poured onto the second layer. This type of footings is most susceptible to settling.
