1. Clear the Area: First and foremost, it is important to clear the area of any debris, rocks, roots, etc. This will help ensure a smoother and more even finished surface.
2. Grade the Area: Depending on the size and nature of the project, some grading may be necessary. This will help ensure a level surface and proper drainage.
3. Compact the Soil: Using a compactor, the soil should be compacted to create a stable base for the concrete.
4. Install a Vapor Barrier: If necessary, a vapor barrier should be installed to prevent moisture from seeping up through the concrete.
5. Install Rebar or Wire Mesh: Rebar or wire mesh should be installed to reinforce the concrete and help prevent cracking.
6. Edge the Form: If necessary, a form should be created around the edges of the concrete to contain it.
7. Install Joints and Expansion Control: Expansion joints should be installed to allow for expansion and contraction of the concrete.
8. Pour the Concrete: Finally, the concrete should be poured to the desired level and troweled to a smooth finish.
Step 1
Dig to the required depth in the earth. Establish the required depth by measuring the concrete slab's height. If the soil is generally damp or has a high proportion of clay, add 2 inches to the depth for gravel. Most concrete slabs will be 1 to 2 inches higher than the ground and 2 to 3 inches below the dirt's surface, requiring 3 to 5-inch hole depth.
Step 2
To create a level surface, use the flat side of a rake to smooth out the ground. Any low locations should be filled up with soil.
Step 3
Use a hand or mechanical tamper to compact the soil. A hand tamper is a long, slender pole with a flat metal base and two side grips. Most hardware stores rent mechanical tampers, which come with instructions on how to operate them. The earth is compacted by the tamper. Walking across the completed product should scarcely leave tracks.
Step 4
For further drainage, pour 2 inches of tiny, rounded pebbles. Tap the rock until it is flat and smooth.
