Step 1: Tools and Supplies
3. Concrete trowel
5. Rebar ties
7. Mag float
9. Measuring tape
11. Hammer- if needed
12. Drill hammer- if needed
Step 2: Grade Your Area
1. Remove or add dirt to your pad until you're 4 to 5 inches deep. The measurement should be from where the top of the concrete will be to the dirt level.
2. You can set heights with wood boards on large pads. On smaller pads, you can just place a level across for your height.
Step 3: Place Rebar Into Walls, If Needed.
1. Drill 5" inwards into the wall with a 1/2" drill hammer bit.
2. Grab #4 rebar and place into the hole. Hit the end of the rebar with a hammer until rebar is inserted the 5".
Step 4: Install Rebar
1. Place your rebar 16" to 18" apart from each other.
2. Tie the rebar at the crisscross sections.
3. Also, tie the rebar from the wall to the parallel rebar if needed.
4. Remove 2 inches of dirt underneath the rebar. You need the concrete to surround the rebar for strength.
5. Add dobies to ensure the rebar is lifted. The rebar should be around 2 to 3 inches from where the top of the concrete will be.
Step 5: Pour Concrete
2. Dump the concrete into your area. Use a woodboard to flatten the top of the concrete for height. It doesn't have to be perfect, but should pretty even.
3. Grab your mag float and start smoothing out your concrete. Add concrete to low areas and holes to fill in voids.
4. Wait till the concrete starts to harden. Constantly smooth the concrete with the concrete troul over the next few hours.
5. Once the concrete is dry and smooth enough then let it dry completely.
