With their professional and reliable service, they ensure that clients' expectations regarding the project are met. At one point concrete contractors were responsible for making the concrete necessary to complete a project. These days, ready mix plants are readily available in most areas so they don't have to do this job.
Concrete contractors first need to determine the concrete shape, size (color, finish, and depth) that will be used. These factors should all be considered before any concrete project can begin. Each option can drastically change what is required, and can have an impact on the final result.
Concrete contractors are responsible for site preparation. This involves backfilling and excavating. Contractors make sure that any rocks, trees or garbage are removed from the site. They also ensure that the ground is leveled, graded and compacted to allow it to support the building's needs for many years. The ground must be prepared to withstand the settling moisture and dirt. This can cause concrete problems which could compromise the structure of the building and the safety and security of those who will live there.
Concrete has the ability to take on many shapes and designs. This is one of the greatest characteristics. Concrete contractors also have to do the formwork. Many innovations have been made to formwork today. Prefabrication is one such innovation. This makes formwork easier, more cost-effective, and less wasteful. They use formwork to create and maintain the concrete mixture in place during concrete hardening to achieve the designs and shapes that they desire. The shapes and forms that are used for concrete can be set in plastic, metal, wood, or a combination of both.
Placing concrete is another important task for contractors. This is where the concrete is poured in forms. The construction team will then move it through the forms with rakes.
