Know About Footings Types in Construction

Footings are an essential component of foundation building. They are normally composed of concrete with rebar reinforcement, which is poured into a dug trench. Footings support the foundation and prevent it from settling. Footings are especially significant in places with unstable soils.

The building of footings by Concrete Contractors Brisbane is best left to professionals who can examine soil conditions and determine the required depth and breadth for the footings, as well as their location. The dimensions of footings are also determined by the size and kind of structure being erected. The placement of footings is critical for providing enough support for the foundation and, eventually, the building.

Four Different Types of Footings

Individual footings

Individual footings are the most popular form of footing. They are typically used for small constructions like sheds and porches. Individual footings are also employed for all four walls of a structure when the soil is extremely soft or there is a high water table.

Combined footings

Combined Concrete footings in Brisbane are utilized when two or more foundation walls are near together and share the weight. Combined footings are also employed when one of the foundation walls is much higher or longer than the others.

Strip footings

Strip footings support a long foundation wall, such as the side of a house. They are also utilized to support load-bearing walls that are parallel with one another.

Raft or Mat Foundation

A raft or mat foundation is a large slab of concrete that supports an entire structure. Raft foundations are utilized when the soil is too poor to sustain individual footings or when the structure is too massive.

How Are Footings Built?

After excavation, the first phase in building is typically to lay footings. The hole for the footing must be dug first, followed by the construction of the footing.

Once the hole has been excavated, the footing must be constructed. This can be accomplished by pouring concrete into the pit or by utilizing prefabricated blocks of concrete, stone, or brick. The footing must be flat and extend past the hole's sides to sustain the weight of the building.

The foundation walls can be erected once the footings by Concrete Contractors Brisbane are completed. The foundation walls are often constructed of concrete, although they can also be built of stone, brick, or wood. The walls must be sturdy enough to withstand the building's weight and tall enough to reach above ground so that the structure does not collapse.
