Footings Explained

Learn about the solid foundation of your home

Posted in News

At Weeks Building Group, we are more than happy to handle your building process from start to finish. But for those of you who are interested in the nitty gritty of your build, we’ve compiled a series of articles on the ins and outs of home construction so you can stay informed and up to date!

First up, what are footings?

Footings are the first element to be laid on your block in the initial stage of construction, and are located underneath the slab. They are most often made of concrete, and prevent your new home from shifting by supporting its load into the ground.

It is important to lay the correct footings in order to prevent your home from moving or leaning, which can lead to cracking or deformation. As such, footings are specified by an experienced and qualified engineer to ensure your home is solid from the very start.

There are many factors that determine what kind of footings you require, including soil type, slope and type of home to be built.

Soils vary from strong to weak, with different natural abilities to support the weight of a home. A strong soil is one that is highly compactable and firm, whereas a weak soil is one that shifts and slides easily. For example, sandy soils can often alter and move, meaning that steel rods may be required to reinforce standard concrete footings.

On sloped sites, footings may need to be placed in a ‘step down’ fashion to allow for the elevation change, or else excavation may be required to level the block.

Footings are also influenced by the type of home to be built. The heavier the home, the larger the footings required. For example, multi-storey homes require more substantial footings to properly support the weight of the home.

The cost of footings can vary substantially according to these factors. Furthermore, unforseen conditions such as underground rocky outcrops or tree roots can cause difficulties with footings, leading to unexpected costs.

Footings are the very base of your new home, which will support and maintain its core structural integrity. It is important to prioritise quality footings in order to ensure your home is stable and solid for generations to come.
