One of the most common problems with concrete is cracks, especially when it is old. Luckily, repairing them is a relatively easy process that requires a few simple steps. Firstly, clean the crack with a brush, then mix a patching material and apply it to the crack’s surface. Make sure to cover the entire crack and let it dry for several hours or overnight. Finally, sand the area with fine-grit sandpaper until it’s level with the rest of the surface.


Another issue that concrete, particularly garage floors, driveways, and patios, faces is spalling, which occurs when the material breaks or flakes. It’s caused by moisture penetration, freeze-thaw cycles, and the use of de-icing chemicals. Restoring the spalled area is simple, begin by chipping out the broken concrete, then apply a polymer-modified cement-based product and allow it to cure according to the manufacturer’s instructions. Finally, level the surface with a concrete resurfacer and let it dry thoroughly.


Pitting happens when small holes form on a concrete surface, leaving it looking rough and ruined. It occurs in high-traffic areas like garages, porches, and driveways, where exposure to chemicals and moisture is common. You can fix it by using a bonding adhesive to coat the surface, then filling the pits with a cement-based repair mix and smoothing it. Wait for the material to cure entirely before sanding the surface to make it even.


Scaling results from the top concrete layer flaking off and leaving the surface patchy, also appearing in areas exposed to extreme weather, salt, and freeze-thaw cycles. The repair requires removing the damaged area and applying a concrete resurfacer using a trowel or squeegee. For small-scale repairs, you can use a patching compound instead of a resurfacer, though with larger areas, this method will not be sufficient to deliver quality results.

Frost Heave

Frost heave occurs when frost penetrates beneath a concrete surface, causing the soil to swell and lift the concrete with it. To repair a badly heaved concrete slab, remove the affected area, add a layer of crushed stone, and install the new concrete slab. For minor lifting, consider being able to inject a polyurethane foam beneath the affected portion to lift up the sunken slab. Any remaining voids in the ground should be filled with a high-density polyurethane foam to prevent further problems.

In conclusion, even non-experts can perform minor concrete repair tasks by using the correct materials and strategies. While many repairs seem straightforward, if they cover large areas or involve structural damage, it’s always best to call a professional. Remember that your driveway, patio, or floor can last for decades if you tackle the signs of wear and tear with regular maintenance and attention to detail.
