Solved! What to Do About Cracks in a Concrete Driveway
Jul 27, · While unsightly, these cracks in a concrete driveway do not indicate underlying structural problems. As long as the rest of your driveway is sound (no heaving, sinking, or crumbling), you can. If the rest of the concrete is sound and the surface is primarily smooth, fix the crazing by applying a concrete resurfacer. This puts a thin repair layer over the cracks. Follow the application instructions for repairing a concrete driveway on the product label.
By Donna Boyle Driveeay. Q: Parts of my concrete driveway are flaky, cracked, and pitted. How do I halt the deterioration and return the surface to its formerly pristine condition?
A: Its strength and durability make concrete a preferred material not only for driveways like yours, but for a range of applications, indoors and out. The good news? Here, the top layer of the concrete flakes away, leaving the surface patchy and pitted while exposing the aggregate underneath. If you ignore spalling, it eventually spreads, compromising the integrity of the surface until crqcking is beyond repair, leaving how to rip music from video no recourse but to rip it out and start over.
After all, spalling starts out as a merely cosmetic imperfection caused by cold weather. When the temperature drops below freezing, moisture in the concrete tends to expand, creating internal pressure. Over crac,ing course of a winter, or over the course of years, as the internal pressure rises and falls, it stresses the surface layer of the concrete, which leads to spalling.
The fix typically involves nothing more than applying a new surface layer to give your driveway a smooth, like-new appearance and to protect it against future damage.
You just need to equip yourself with the right materials and follow the simple steps outlined below. Specially formulated to restore lackluster concrete, resurfacing products like Rapid Set NewCrete available from The Home Depot make it quick and easy for homeowners to address spalling on their own, without having to hire a contractor.
The resurfacing material simply spreads over the existing, spalled concrete surface to create a fresh, flawless finish. NewCrete in particular stands out, because it simplifies and speeds up the process. For one thing, it rarely requires the use of primer. For another, you can consider the job done as soon as the product has been applied, because in most conditions, NewCrete cures all by itself. You can return to regular use of your driveway after only 60 to 90 minutes. First things first: Thoroughly clean the driveway by means of a pressure washer, using the high-powered tool to remove dirt, dust, and debris—really, any extraneous material that could potentially interfere with adhesion and bonding.
In some situations, a crqcking grinder may be needed for proper preparation before using the pressure washer. Not many tools are needed—only a long-handled squeegee view example on Amazon and a cordless drill chucked with a paddle-type mixer view example on Amazon.
In a bucket, tub, or how to store bed sheets, combine the resurfacer with water in the ratio recommended by the manufacturer. Next, after lightly dampening the driveway, prefill any cracks or holes with a small amount of the mixture. With that done, pour the rest of the resurfacer onto the driveway and, with your long-handled squeegee, push and how long to bbq lamb cutlets the material across the surface to cooncrete an even layer up to an eighth of an inch thick.
Indeed, you can use resurfacer to revive just about any worn-out concrete surface. In especially dry, windy, or hot conditions, it may be necessary to mist the area while the resurfacer gains strength.

By Glenda Taylor and Bob Vila. Is repairing a cracked driveway a do-it-yourself job, or will I need to hire a contractor? A: While concrete is certainly one of the most durable construction materials around, over time it can develop cracks and other types of problems. For the most part, fixing driveway cracks is a relatively simple do-it-yourself project. While unsightly, these cracks in a concrete driveway do not indicate underlying structural problems.
This cement-based product contains polymer modifiers and additives that are designed to form a durable and permanent bond with the existing concrete. The existing concrete must first be meticulously cleaned with a high-power pressure washer. Check out this slab-resurfacing video from the Quikrete team for complete instructions. Like spider web cracks, these small cracks do not indicate a larger problem, and they often show up soon after the concrete is poured.
Sealing can prevent bigger problems down the line, and the non-sag consistency and matte gray color of Advanced Polymer Concrete Crack Sealant will even out the surface and is textured to blend into the existing driveway, disguising the fact that there ever was a crack. Flexibility is key to a good sealant. Because concrete expands and contracts slightly with temperature changes, the sealant needs enough give to not pull away from the edges of the crack.
After that, filling small cracks is an easy DIY project, but for the best results, watch this concrete crack repair video before you start. This type of crack is typically caused by a heavy vehicle driving along the edge of the driveway and putting pressure on the outside edge, the weakest spot. By thoroughly cleaning the cracked or crumbled edge, and then mixing and applying the two products as demonstrated in this instructional video , you can restore the edge of your driveway to its original good looks.
In cases where entire corners of a concrete driveway have broken off, using a structural repair material like Quikrete Polymer Modified Structural Repair that is easily sculpted and shaped to reform the edge is great choice. When large slabs of concrete are poured, the contractor either forms or cuts joints every eight to 10 feet, with the goal of limiting any shrinkage cracks caused during the curing process or by future slab movement.
In this way, cracking is hidden deep within the joints so the smooth surface of the driveway is maintained. Unfortunately, a control joint may widen and separate over time, creating a gap that detracts from the overall look of your driveway—and it could get worse. If left alone, the crack can fill with debris, and vegetation can start to grow. Be sure to clean the crack thoroughly before you apply the sealant, using a standard caulking gun.
Find out how in this instructional video. These could indicate an underlying structural problem, especially if the surface of the driveway is higher on one side of the crack than the other. Though the project may sound intimidating, this helpful slab-pouring video from Quikrete will tell you everything you need to know. This content has been brought to you by Quikrete.
