Over time, concrete sinks deeper into the ground on which it rests, causing dips, sinking, holes and cracks. This is a normal occurrence for concrete, especially heavily used concrete such as driveways. If your concrete driveway has deteriorated to the point at which there is standing water after a rainfall, you may go hole by hole to fix the problem and make the driveway smooth.
Clean the surface of the spot you intend to repair with a broom to remove any loose chunks and dust/dirt.
Put on the face mask and apply the concrete cleaner to the entire surface as directed by the manufacturer. Follow all safety precautions listed on the container as improper use can damage you and/or the concrete and tools.
Soak the surface with water for 20 to 30 minutes, then use a rag to absorb excess water. Don't rub the concrete surface itself with the rag; the surface should stay damp.
Mix a small amount of a thin concrete mix per manufacturer's instructions, then add approximately twice as much water as it calls for. Take a brush and apply the thin mix to the entire surface to prime it for the larger concrete application. If desired, use concrete adhesive that can be applied in the same way, instead of a thin concrete mix.
Mix the larger batch of concrete per manufacturer's instructions. Apply as much of it as is needed to the surface. Once the concrete is on the surface, take the cement smoother and evenly smooth out the new concrete across the entire area. If you need more concrete, quickly make a new batch and add it to the area. If you used too much, scoop some of it out with the cement smoother and re-smooth the surface.
Allow the concrete to set for the length of time specified on the container or bag before using that area of the driveway.
