An asphalt or concrete driveway or parking area installed in your yard should be regularly maintained to keep it free of cracks, damage, and weed growth. Here are some tips to help you care for and maintain your paved parking and driveway area.
Concrete is one of the most durable types of pavements, but as it ages, it can form cracks through its surface that become filled with dirt and sediment. Over time, this sediment collects vegetation and weed seeds, which sprout in the cracks, widening the cracks. Then, freeze-thaw patterns of winter occur as snow and ice melt to collect within the cracks, then freeze again when temperatures fall. As water expands when it freezes, this forces the cracks in the concrete to widen as well. For these reasons, it is important to take care of your concrete to clean out the cracks and patch them, when necessary.
First, dig out any vegetation growth from the cracks, using the end of a screw driver or sharp edge of a garden trowel. Clean the surface of the concrete with a concrete degreaser cleaner to remove any grease residues from vehicles, which can prevent your repair from adhering into the crack. Next, clean out the dirt from the crack using a broom or water from a pressure washer or garden hose with a nozzle attachment.
You will need a container of concrete patching compound, which you can mix up right before you apply it into the cracks of your concrete. Follow the instructions on the container to add the appropriate amount of concrete patching compound. Press the compound into the crack, filling it from its base, using your concrete trowel. Be sure to press out all air bubbles. Then smooth the surface level with the surrounding concrete area.
Asphalt is a durable paving material that has a small amount of flexibility in warm weather when the sun shines upon its surface. Unfortunately, asphalt can begin to break down and dry out from sun oxidation, which leads to cracks that form over its surface. Dirt and other sediments collect inside the cracks to provide a place for vegetation seeds to germinate. Vegetation growth leads to an increase in size of the cracks. As the asphalt dries out further, a cracking pattern can form over the surface of the pavement.
Similar with repairing concrete cracking, you will need to remove any vegetation growth from the cracks and clean out dirt and sediment. Then, you can fill the cracks with a cold patch asphalt material. Tamp down the patched area with an asphalt tamper or the end of a four-by-four wooden post.
After you have patched any cracks, clean the surface of the asphalt with a degreaser cleaner. Next, you should apply a protective seal coat emulsion to restore moisture and flexibility to the asphalt and give it a waterproof protection.
