If you have a gravel driveway but are considering a concrete one, then you will need to know how to edge your concrete driveway. One of the common ways to edge a concrete driveway is to use a concrete edging tool around the perimeter of the driveway while the concrete is still wet. This creates a large half-circle depression in the driveway that can warn people when they are coming close to the edge. Another way to edge your concrete driveway is to lay small concrete barriers or pressure treated 4-inch by 4-inch wood around the edge of the driveway. If you want a decorative edging idea, plant shrubs around the perimeter of the driveway and keep the sides of the shrubs that face the driveway trimmed flat.
