Construction Process of Residential Concrete Foundations
The construction process of a residential concrete foundation involves several steps that must be carried out with precision to ensure a strong and durable foundation for the home. Here is a breakdown of the construction process:
Site Preparation
To ensure the stability of the foundation, clear any debris, rocks, or obstructions from the site that could impact its integrity. Level, grade, and compact the site thoroughly to create a flat and even surface.
Formwork Installation
Formwork, or shuttering, is a temporary structure containing concrete while it sets and cures. The formwork is typically made of wood or metal and is set up in the shape of the foundation walls and slab.
Concrete Pouring
After installing the formwork, the construction team carefully pours the concrete into the forms. They meticulously distribute the concrete to achieve an even distribution, eliminating any air pockets or voids that could compromise the strength and integrity of the foundation.
