The process of installing a new concrete slab typically involves the following steps:
Site preparation: The first step in the process is to prepare the site where the slab will be installed. This involves clearing the area of any debris, rocks, or vegetation, and leveling the ground.
Depending on the application, purpose of use and project specs- soil compaction may be required and a moisture membrane to be laid on top of the soil.
Formwork: Once the site is prepared, the next step is to create a formwork, which is a structure that will hold the wet concrete in place while it sets. While the formwork is usually made of wood, it can also be made of metal, or plastic and is placed around the perimeter of the slab.
Reinforcement: Depending on the size and intended use of the slab, reinforcement may be required. This can be done using steel bars, wire mesh, or fiber mesh according to specifications and requirements.
Pouring the concrete: With the formwork and reinforcement in place, the next step is to pour the concrete. This involves mixing the concrete according to the manufacturer's instructions and project requirements and then pouring it into the formwork. The concrete is then leveled and smoothed out using tools such as a screed.
Finishing: Once the concrete is poured and leveled, it will begin to set. During this time, the surface can be finished using various techniques, such as troweling, stamping, or polishing.
Forms removal: usually the forms shall be removed within 12-24 hours from the time of pouring.
Curing: After the concrete is finished, it must be allowed to cure, which means that it will harden and strengthen over time. This process can take several days to several weeks depending on the conditions.
Sealing: Once the concrete is fully cured, it may be necessary to apply a sealer to protect the surface and extend its lifespan.
Overall, the process of installing a new concrete slab requires careful planning, attention to detail, and the use of specialized tools and materials.
