Like anything else, concrete driveways need to be maintained. Concrete is a very durable building material and an excellent material with which to pour a driveway. Basically, concrete is a mixture of sand, aggregate, water, and cement. Best Concrete Driveway Crack FillerThe cement is the base in which the sand is embedded and glued together with the help of water. While we all think of concrete as being very strong, it can be damaged by freezing water, standing water, excessive heat, expansion and contraction of the sand or aggregate from which it is made, shifting of the ground, tree roots, over loading, and even certain kinds of bacteria. Its strength is compression, but it is weaker in tensile strength (pulling) so things like this can easily cause it to crack. Fortunately, repairing most concrete driveway cracks today is a relatively inexpensive, straightforward do- it- yourself project. Resurfacing Concrete. Asphalt driveways have always been popular because they are much less expensive than concrete and easily repaired. ![]() Diy Driveway Sealing CracksOne needs only to scratch out the cracks, clean and scour the surface to aid in bonding, and then pour a thin layer of asphalt on the surface. Compress and leave to cure for a few days and the driveway looks good as new. Years ago, worn concrete driveways were typically replaced and required a very strong back because the old driveway needed to be jack- hammered and the old concrete carted away. Today, there are acrylics and polymer- based cement mixtures that can be used to resurface your old driveway more easily than resurfacing asphalt. One manufacturer makes a driveway repair product made with Portland cement and polymers, which is mixed with water, and can be simply applied with a squeegee or broom. W word of caution: it cures very quickly. Once you add water, you have but 3. That said, it does a great job and truly rejuvenates the driveway. 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. Moral of the Story. Repairing cracks in a concrete driveway is a simple project for most DIYers. Whether or not your driveway needs a complete overhaul or just the repair of small weathering cracks, there are products available that make the job easy. An ingenious way to fill gaps between concrete driveway slabs. June 1. 5, 2. 01. By Tim Carter, Tribune Media Services | Ask The Builder. DEAR TIM: My concrete driveway has eight large slabs. The driveway slopes down from my garage to the street. The straight- line gaps between the slabs has enlarged, and some cracks are as wide as 2 inches now. I patch them and they open up again. Is there a guaranteed way to repair these cracks so I don't have to do it every other year? Ed S., Steator, Ill. DEAR ED: Concrete cracks of any type are the bane of many a homeowner. They can be in flat slabs, retaining walls, foundation walls and steps. Concrete has fantastic compressive strength, but usually only 1. This lack of tensile strength explains, for the most part, why concrete cracks. It's impossible to cover this topic completely in this tiny column. Entire books have been written about concrete crack repair. I'll just focus on your situation and give you an interesting option. First, your driveway looks to be in great shape, other than the gaps between the slabs. That makes a repair job much easier and more likely to be aesthetically pleasing. It's important that the repair be functional while not detracting from the overall look of your driveway. If you try to fill the cracks with a hard material, such as more concrete that contains small aggregate like pea gravel or very coarse sand, it will eventually crack as well. The gaps you have are far too wide for most institutional and commercial caulks designed for filling concrete cracks. Doing a specialized and exhaustive search on the Internet, you may discover some product used by airports, state departments of transportation or other owners of massive amounts of concrete pavement that will fill those massive cracks. But the look of the repair may not be in your best interest. I recommend that you repair the cracks with wood. I know that may sound nonsensical, but wood and concrete have been used for years together. It was a fad in the 1. I've inspected houses with this combination, and the redwood appeared to have lasted for well over 2. Because of the natural water repellents that are in redwood, it would last for decades, even though it was exposed to moisture in a slab on the ground. Using some new water repellents and drainage aids, I believe you can get strips of wood to last at least 3. The first thing you need to do is clean out the gaps between the slabs to the thickness of the slabs. Scrape off any old patching tar with a stiff putty knife and remove residual tar or asphalt compounds with mineral spirits and gentle scrubbing with a wire brush. Dig a 4- inch wide trench along the sides of the slabs from the crack or gap closest to the house all the way down to the street or sidewalk. This trench should be a deep as the slabs are thick. Fill the trenches on either side of the driveway with small, rounded pea gravel (the size of marbles or peas). Do the same for the gaps between the concrete slabs, but stop filling the gaps about 2 inches from the top of the slabs. Buy some redwood or other fine- grained lumber, like teak, that is naturally resistant to rot. Cut the strips of wood to fit each of the gaps, making sure the shape of the strips is wider at the top than at the bottom. This tapered shape will allow you to tap the pieces of wood into the gaps between the slabs with little effort. Each strip should be cut so that it's 1 3/4 inches from top to bottom. This dimension allows the wood to be recessed below the top of the slabs about 1/4 inch. Before you install the wood, completely coat all the sides, edges and ends with three coats of a high- quality synthetic resin water repellent. It's very important that the ends are well coated. In fact, I would dip the end of each piece of wood into the can of the sealant for at least two minutes allowing the water repellent to be drawn deeply into the end grain. SIDEBAR Once the wood strips are in place, fill any small gaps between the wood and the concrete slabs with medium sand. The sand will be natural looking and it will finish off the job nicely. The pea gravel under the wood strips and on the sides of the driveway acts as an interconnected series of drainage channels that will remove any standing water from around the wood. This will significantly extend the life of the wood strips. Want free home- improvement information? Go to http: //www. Askthe. Builder. com and sign up for Tim's free newsletter.
