Step 1 - Site Work. Before concrete can be poured, the site needs to be prepared to reduce the chance of heaving from expansive soils and frost. On small projects, use hand to tools to clear the area of all grass, rocks, trees, shrubs, and old concrete, exposing bare earth. Earth moving equipment speeds up the process, especially for large pours.
