The Beginners Guide To (From Step 1)
A home, business, or any structure that sits on the ground needs a strong foundation. There are different types of foundations, and the type that is best for your structure will depend on its design, location, soil, and budget. Concrete foundations are an excellent choice for many projects. They will make your structure stronger and more secure, and they are permanent.
There are two basic types of concrete foundations: poured concrete foundations and concrete block foundations. While poured concrete foundations are sturdier, concrete blocks tend to support more weight in the top. You should consult your construction company when choosing a type of foundation for your building. Changing your foundation type is not a simple process.
The thickness of a footing must be a minimum of 6 inches. The width of the footing should extend two inches beyond both sides of the foundation wall. A footing thickness that is too thick can lead to flexure of the building. Make sure to consult your local building code before deciding on the thickness of your footing.
Residential concrete foundation walls are typically 6 to 10 inches thick. Their compressive strength is between 2,500 and 3,000 psi. Higher tensile strength can be obtained by increasing the thickness of the wall and installing horizontal and vertical shear reinforcement. This method is known as shear friction, and it relies on the resistance of the concrete and dowel action of the reinforcement. Regardless of the method, however, a concrete foundation wall’s capacity is determined by the concrete strength and the thickness of the reinforcements.
A concrete foundation can last more than 100 years. This type of foundation will withstand a building’s weight and weather conditions. As a result, a concrete foundation is an excellent option for new homeowners. Depending on the concrete price at the time of installation, a home-sized concrete foundation may cost $10,500 or more. The price for a larger foundation, however, can be significantly higher.
Concrete is made up of Portland cement and other materials. Its density depends on the types of aggregates used in its mix. Normal-weight concrete has a density of approximately 144 to 156 pounds per cubic foot. This is the most common type of concrete used for residential foundation walls. If you need a more durable concrete for above-grade applications, choose Type III cement.
A concrete slab dries faster than a poured basement. Because it dries faster, a concrete slab minimizes the risk of flooding and gas leaks. In addition to being more durable, a concrete slab is quicker to construct than a traditional basement. You don’t need to wait days for a concrete slab to dry, which makes it a great choice for those with a tight budget.
Another important consideration when selecting a foundation is climate. In areas where termites and other wood pests are common, it would be wise to avoid a wood foundation. Cold climates often cause slab foundations to crack. You’ll also want to consider the type of soil you live in and the type of compaction in the ground.
