Pour a Concrete Slab

Steps 12 (cont.) & 13

Where you cannot reach across the slab, place two pieces of plywood, each about 2 feet square and screwed into 1-by-2 handles (to make the plywood easy to pick up), on the concrete. One piece is for your knees and one is for your feet.

When you need to move, pick up the foot piece and kneel on it, and put the piece that was under your knees under your feet.

Step 13 (shown here)
Cut the edges.

Slip a mason’s trowel between the inside of the form boards and the concrete and slide all along the perimeter of the slab. This will eliminate the pockets of air that can weaken the concrete.
