What is the purpose of an edger in concrete work?

The purpose of an edger in concrete work is specifically to produce a neat rounded edge along the slab perimeter. This tool is used at the edges of a concrete slab to create a finished edge that helps prevent chipping and cracking while enhancing the overall aesthetic appearance of the concrete. By producing a rounded edge, an edger also aids in facilitating the drainage of water away from the slab, which can further protect the integrity of the concrete over time. The rounded edge helps to provide a professional look, making the finished product more visually appealing and durable.
