PREP FOR PROJECT
-
Measure the area you wish to pour the concrete. VERY IMPORTANT!
-
The formula for concrete is width x length x depth, divided by 27
-
Example: 1/4 = 0.25

BEFORE YOU POUR
-
Purchase forms. Most commonly used are 2x4 planks with stakes placed every 18 inches.
-
Lay out the corner position of the slab. Use your stakes and twine. Run along edge to each corner.
-
Measure diagonally from corner to corner. Ensure that all measurements are equal.
-
Place form board at corner and alongside your twin. Stake so 1/8" is above your twin. Be sure to stake deeply enough for the forms to have the strength to hold your concrete.
-
Prepare the area by compacting the material you have chosen as your sublease. We most commonly use gravel. You will want about 4-6" of sublease, in some cases you may need more.

POURING + FINISHING
-
Wet down the sublease in your formed area with a hose.
-
Pour concrete out of the BB cart trailer. In some cases you may need to pour into a wheelbarrow, and then dump the wheelbarrow. Spread concrete with square shovel or rake during this step to fill the form evenly.
-
Use a 2x4 screed board to level. Move back and forth and move from each end. You will need to work quickly to finish before concrete sets.
-
Used a bull float to compact the concrete and allow gravel free concrete to come to the surface. Move away from you and back toward you while keeping the tailing end slightly elevated.
-
Take a hand float to the surface using sweeping motions after water bleeds to the surface.
-
Use an edger and move it along the edge of your form. This will ensure clean edges when your form is removed.
-
Sweep a soft bristled brush across the surface once it can hold your weight. This will add design and traction to your concrete.
