Sidewalks are made of concrete and can last for many years but sometimes they may crack, chip or sink due to weather conditions, movement of the soil, or just general usage. Fixing these problems at an early stage would avoid their escalation, reduce expenses on replacement, and provide a stable surface. In this guide, I will show you easy ways of fixing some of the most frequent sidewalk issues, including cracked surfaces, small pits, or wavy slabs.
Step 1: Clean the Area
For a deeper look into cleaning and preparing your sidewalk for repairs, check out this guide on how to pour a concrete sidewalk in easy steps. A clean surface will guarantee that the repair materials stick well to the existing concrete. Sweep the area with a stiff bristle broom to remove debris dirt and any loose concrete pieces from the floor. In case the cleaning is more thorough, you might need to use a pressure washer to wash off the remaining dirt and dust. When repairing cracks ensure that you remove all the small stones or any other particles within the crack since they hinder the filler from setting.
Step 2: Choose the Right Repair Material

For small cracks, the use of a concrete crack filler or patching compound is adequate. These products are easily found at most hardware stores and are usually dispensed in bottles with a squeeze nozzle or in tubes. If the crack is deeper or has a hole it may be necessary to use a concrete patch mix which is a stronger mix used for more intensive repairs.
Step 3: Repairing Small Cracks
For small cracks, you can use a concrete crack filler. Here’s a simple process:
1. Apply the Filler: Apply a crack filler that is suitable for small cracks and is a concrete crack filler. These are in tubes that are already prepared for use by the user simply squeezing it directly into the crack. Use a little at a time and rub it on the crack from one end to the other.
2. Smooth the Surface: When applying the filler, level it with the surface of the surrounding area using a trowel or a putty knife. This assists in the blending of the repair and gives a flat finish.
3. Allow to Dry: Follow the manufacturer’s instructions for drying times. Avoid stepping on or disturbing the area until it’s fully set, as this can affect the bond and the durability of the repair.
Step 4: Patching Large Cracks or Holes
For larger cracks and holes, use a concrete patch mix. Here’s how:
1. Prepare the Mix: Follow the instructions on the package to mix the patch compound. It should be thick enough to hold shape but still spreadable. If you’re using a pre-mixed compound, it’s ready to go without additional mixing.
2. Fill the Area: Use a trowel to apply the patch mix into the crack or hole. Press firmly to ensure the compound fills all gaps and adheres to the surrounding concrete.
3. Level the Patch: Smooth the surface with a trowel until it’s level with the sidewalk. Feather the edges to blend with the rest of the concrete. This creates a seamless repair that’s less noticeable.
4. Cure the Patch: Allow the patch to cure for the recommended time. Avoid walking on it or placing any weight on the repair until it’s fully hardened.
Step 5: Resurfacing the Sidewalk (For Widespread Damage)
Resurfacing involves applying a thin layer of concrete over the entire surface, giving it a fresh, smooth appearance. Here’s a basic guide:
1. Prepare the Surface: Ensure the sidewalk is clean because any material on the surface will hinder the resurfacer from sticking properly. A pressure washer is useful in washing off dust, dirt and also old concrete particles.
2. Mix the Resurfacer: It is recommended to mix the resurfacing compound according to the instructions on the product package. The consistency should be like that of pancake batter so that it spreads uniformly on the concrete surface.
3. Apply the Resurfacer: Spoon the mixture onto the sidewalk and then use a scraper or a trowel to level it. Act fast because the resurfacer can start to harden in about 20-30 minutes.
4. Finish the Surface: To this, you can add more traction by lightly brushing the surface after spreading to give it a rough feel. This step is not mandatory but it is advised in order to avoid slipping especially when the ground is wet.
5. Allow to Cure: Allow the resurfaced area to cure according to the manufacturer’s instructions on the product used. Avoid anyone walking on the area until it has had time to set properly.
Maintaining Your Concrete Sidewalk
Sidewalk maintenance can help you avoid frequent repairs and also increase the lifespan of your sidewalk. Ensure the surface is clean by sweeping it frequently and avoiding the accumulation of any substances that may cause the formation of moisture on the surface. Do not use strong chemicals for de-icing during winter since these chemicals will damage concrete surfaces gradually. For concrete surfaces, sand or safer de-icing products should be used in place of the above.
