Cracked concrete

Repairing Cracks in Concrete Driveway or Walkway

Although concrete is one of the strongest building materials and is commonly used for building driveway and sidewalks, Mother Nature still has a way of moving things around, causing the concrete to crack. Before it gets bigger and allows water and debris in, which will help it get worse, you need to repair the cracks

Repairing cracks in concrete is an easy DIY project with today’s repair materials and a little guidance.

Patching Concrete Cracks

Clearly not all repairs require resurfacing the entire driveway. Driveway cracks come in a host of sizes and shapes—from hairline cracks to more significant fissures. Regardless of the size of the crack, there a few simple steps that should be taken before fixing the crack.

Clean It – The crack should be cleaned thoroughly to ensure proper bonding between the old surface and the repair material. Cleaning entails removing loose pieces of the old concrete with a chisel or equivalent tool and then removing the remaining debris with a wire brush and sweeping it away.

Fill It – The crack can then be repaired and filled with something as simple as concrete caulking for hairline cracks or concrete sealer (pourable concrete mixture) designed to fill larger cracks. You should also use a trowel to compress the material firmly into the crack.

For an aggregate driveway, you will want to pour sand over the concrete patch and roll over it with a somewhat heavy object.

Let It Cure – Once the patch is in place, it has to be allowed to dry and cure before you park a car on it. Curing is not the same as drying. Pourable concrete is easier to work with than the polymer coatings, not only because you are working on a much smaller area than you would be if resurfacing an entire driveway, but because they typically dry more slowly, allowing you time to work, plus many patching products are designed to cure quickly, to reduce the wait after you’re done. Obviously, referring to the manufacturer’s instructions will alleviate any difficulties.

If you’ve used sand on the crack of an aggregate driveway, sweep or wash away the excess after the curing process has finished.

Seal It – Concrete is porous and water is one of the major culprits that can do damage to your driveway. To help minimize water damage, it is always a good idea to regularly apply a high-quality water sealer.

  1. As a 20 year concrete contractor these steps will not help repair a crack ! Consult a concrete professional before attempting repair to save yourself from wasting money that could be used to actually repair the problem properly!

  2. 27 years in the concrete industry and this is all bullshit. It will look good for a very short time then you will have to hire a professional to repair it anyway. First thing to do is call a concrete manufacture and let them look at your problem and they will recommend the best way to repair it.

  3. How about give the individual who even took the time to write the article some credit. There are a million ways to perfection and everyone has their own viewpoint. Appreciate the post.

  4. I use a mortar / concrete patch material that comes in a tube from lowes and home depot. I fill so many stress and settling cracks on properties. And it bonds great. And have had no problems to date with any of the repairs. I have homes that are up to 2 years old. That are still in tact. I service foreclosure properties all over florida. Never had a repair fail to date. All of the so called professionals will always discredit things like this. Because they want you to pay over priced fees to them. The repairs i do and the material i use was advised to me by a concrete specialist like the same guys ragging on this page. Same materials he uses. So why not let the home owner do the repair and save some serious money.
