If you have holes in your driveway's asphalt, you may worry about making them bigger every time you drive your car over them. If so, use the following three-step guide to patching the holes.
Step 1: Clean The Asphalt Around The Holes
The first step is to clean the asphalt around the holes. This gives the cold patch a clean surface free of debris on which to stick. For this step, you will need a stiff scrub brush, grease-cutting dish detergent and a garden hose with an adjustable spray nozzle.
Apply a small amount of the detergent on the bristles of your wet scrub brush. Then, starting from the edge closest to the hole, gently scrub using small, circular motions. Do not apply too much pressure if the asphalt is brittle, as this could bust the pavement and make the hole bigger.
If you find any areas that have oil stains, apply the dish detergent directly to the asphalt. Work it into the pavement with the brush, then let it sit for about an hour. The grease-cutting properties of the detergent should loosen up the oil enough to remove most of it with a second scrubbing.
Continue scrubbing the area around the hole until you have completely cleaned an area about three to four inches around it. Then, turn on the water hose, and set the nozzle on a medium mist. Do not use the highest setting, as this could break the asphalt apart. Thoroughly rinse the area until no soap suds remain. Let the area air dry, then go on to the second step.
Step 2: Remove Any Loose Pieces In And Around The Holes
After the asphalt is dry, the next step involves removing any loose pieces in and around the hole. If these bits of asphalt are left when you patch the hole, the patch will not have a stable surface and could crumble relatively quickly.
You can use your hands to remove any pieces that are very loose or broken off. However, if you come across a piece that is loose but will not budge with your fingers, use a flathead screwdriver to pry it free. Repeat for each hole, then go proceed with the third step.
Step 3: Fill The Holes With A Cold Patch
Once the area around the holes are clean and any loose pieces have been removed, you can start filling the holes with a cold patch. You can find pre-mixed patch material in hardware stores and department stores with home and garden centers. You will also need a trowel and something to tamp the patch down with, such as the end of a 2x4 board.
Use the trowel to fill the hole with the cold patch material until the filler reaches about a half of an inch above the surface of your driveway. Then, using the end of your board, firmly and repeatedly tamp down on the patch until it completely fills the hole.
Once you are done tamping the patch, look closely at the hole to make sure it does not dip down lower than the driveway's surrounding surface. If it does, place a small amount of the patch on top of the hole where the depression exists, and tamp it down again. Repeat until the patch is level with the pavement.
Once you have patched all of the holes in your driveway, you may want to seal it to ensure no further damage is done to the surface. If you do not feel comfortable sealcoating your driveway yourself, you may want to contact paving contractor to discuss your options.
