The construction of a concrete floor slab involves several key steps to ensure a durable and level surface. Here’s a concise overview of process:
Site Preparation: The area where slab will be placed is cleared of vegetation, debris and any existing structures. The ground is then graded to create a level surface, ensuring proper drainage.
Excavation: Depending on design, excavation may be necessary to reach required depth for slab. This step may involve digging out soil to accommodate thickness of slab and any underlying materials.
Subgrade Compaction: The soil beneath slab is compacted to provide a stable base. This step is crucial to prevent settling and cracking in future.
Formwork Installation: Wooden or metal forms are set up around perimeter of slab area to contain concrete. The forms are leveled and secured to ensure slab maintains desired shape and height.
Reinforcement Placement: Steel rebar or wire mesh is placed within forms to provide additional strength to slab. This reinforcement helps prevent cracking and enhances slab’s load-bearing capacity.
Pouring Concrete: Ready-mix concrete is delivered to site and poured into forms. It is spread evenly and worked into place using tools like shovels and rakes.
Finishing: After pouring, surface of concrete is finished to achieve desired texture. This may involve smoothing with a trowel, adding a broom finish for traction, or applying decorative techniques.
Curing: The concrete must cure properly to gain strength. This typically involves keeping surface moist for several days, either by covering it with wet burlap or using curing compounds.
Form Removal: Once concrete has cured sufficiently, forms are removed. Any necessary edge finishing or sealing can be done at this stage.
Final Inspection: Slab is inspected for levelness, surface quality and any potential issues before it is put into use.
The cost of concrete floor slabs varies depending on type and complexity. Basic slabs typically cost between $4.00 and $8.50 per square foot, while reinforced slabs range from $6.00 to $11.50.
Decorative slabs such as stamped or exposed aggregate are more expensive, costing from $8.50 to $15.00 per square foot due to additional labor and materials required. Polished slabs, offering a smooth and glossy finish, typically range from $8.00 to $15.50 per square foot.
