Everything You Need To Know About Concrete Foundations
Posted on: 25 September 2023
When it comes to constructing a building, the most essential part of the entire process is the foundation. The foundation serves as the support system of the building, ensuring that it stands firm even with the weight of the entire structure on top of it. Concrete foundations have become increasingly popular in recent years, primarily because of their durability and longevity. For new construction or renovation projects, here are key facts about concrete foundations you should know.
What Is a Concrete Foundation?
In the context of construction, a foundation refers to the base of a building that lies below ground level. A concrete foundation is constructed by pouring concrete into a trench that's been dug out to the right depth necessary for the building. Simple construction may only require a slab foundation, whereas a structure with more weight may require a deeper foundation. Concrete foundations are highly durable and can last for several years, making them a dependable choice for construction.
The Importance of Preparing the Site Before Concrete Pouring
Before pouring the concrete, the site needs to be appropriately prepared. This involves leveling the ground, backfilling, the installation of drainage or waterproofing systems, and, most importantly, the establishment of a concrete formwork. The formwork gives a mold into which the concrete is poured, ensuring that it takes the specific shape and dimension of the building plans.
Types of Concrete Foundations
Several types of concrete foundations can be used in construction, but the most common ones are the slab and the pier. A slab foundation is built by pouring concrete into a specific area, usually a trench, to form a flat, solid surface. Slab foundations are typically used in areas with warmer climatic conditions as they offer a more efficient form of insulation. A pier foundation, on the other hand, uses reinforced concrete columns to form a broad base that sinks deep into the ground, providing ample support for the building. This type of foundation is usually used when constructing buildings on unstable soil or ground with a high water table level.
The Cost of Concrete Foundations
Compared to other foundation types, concrete foundations generally incur higher costs due to the expenses associated with raw materials and labor. However, the cost varies depending on the size, shape, and complexity of the building, the climatic conditions and soil stability, and the current market price for raw materials.
