Driveway Repair Charleston SC involves addressing damage, cracks, potholes, and more. Isolated cracks and a badly faded seal coat surface can be addressed through patching and filling, but larger potholes or alligator cracks require resurfacing to save the structure of your driveway.
Small cracks can be filled with cold patch asphalt to prevent further damage. Regular maintenance, such as applying herbicide and cutting weeds growing through the cracks, is key.
Potholes are deep depressions that can occur in asphalt roads, parking lots, and driveways. They are formed when water seeps into cracks and freezes during cold weather, causing the cracks to expand, push up against the top layer of pavement, and eventually create holes. Potholes are a nuisance to drive over, and they can damage the tires, shocks, and alignment of vehicles. They also pose a trip hazard for anyone who walks on the driveway, so they need to be repaired as soon as possible.
There are several different ways to repair potholes, depending on the materials and climate conditions. However, most methods involve filling the hole with coarse gravel or cold mix asphalt and tamping it down firmly. This is the most effective way to ensure that the pothole is not displaced by vehicular traffic or wash out again in the future.
It is important to remove any plant matter or debris from the pothole before filling it. Once the area is clean and free of loose material, it should be filled with a high-performance blacktop repair mix, which combines stone and asphalt binder. The material should be added in layers and compacted with a hand tamper or a 4×4 wooden post. After the pothole is repaired, it should be raked to blend in with the surrounding surface of the driveway.
Dirt and gravel driveways are less prone to potholes than concrete, brick or asphalt, but they can still develop dips and bumps over time. To prevent them from becoming too large, regular inspections should be conducted and any issues promptly addressed. It is also a good idea to hire a professional for routine grading, which redistributes the gravel and helps to prevent the formation of potholes.
Taking the proper steps to repair potholes will help your driveway last longer and reduce maintenance costs. For dirt and gravel driveways, it is best to fill them with a coarse gravel that matches the surrounding surface of your driveway. This material is easy to apply and can be tamped down using a hand tamper or improvised with a piece of wood or an old car tire.
Cracks
Cracks in your driveway not only damage the concrete, but can allow dirt and weeds to seep in. These can further degrade the concrete and cause even more serious damage over time. It’s important to regularly inspect your driveway for signs of damage and take prompt action to repair any cracks.
A good quality silicone-based caulking is a quick and cheap option for repairing cracked concrete. However, the sealant may only last for a few years and will require frequent reapplication. A professional concrete service should be contacted for permanent repairs, including using a chemical solution that is injected into the driveway to fill and stabilize the cracks.
For a more lasting repair, use a concrete patching compound or resurfacing mix with a bonding agent. Follow the manufacturer’s instructions for application and curing. A bonding agent is especially important to use when repairing large cracks. This will help ensure that the new concrete will adhere properly to the existing surface.
Wide fissures typically indicate a major structural issue. While you can try to fill these with a commercial crack filler, they are likely to open back up over time. A concrete professional can assess the underlying issues and provide appropriate services, such as concrete lifting, to fix the problem permanently.
Before applying your crack filler, clean the area thoroughly and remove any weeds or debris from the cracks. It’s also a good idea to sand down the affected areas for a smoother finish. It’s best to apply the crack filler in warm weather, so the material has a chance to dry and harden properly.
Once the crack filler is applied, use a pointing trowel to push it into the cracks and “stuff” them. Be sure to apply an ample amount of the product to fully fill the cracks and avoid leaving bare spots. The crack filler dries to a light gray that blends well with many driveway surfaces.
Large cracks can pose a safety hazard for drivers and pedestrians, so it’s important to repair them as soon as possible. If the same areas of your driveway continually crack, this indicates a deeper, structural issue that requires professional assessment and treatment.
Stains
Stains on concrete or asphalt can be an eyesore and detract from the overall appearance of your property. Many can be removed with basic household products, but if stains are old and stubborn, an acidic solution may prove helpful. Using a commercial concrete cleaner can also help remove stubborn organic material or rust, as well as discoloration caused by weathering.
Oil stains are the most common type of stain on driveways. While they are more visible on concrete than asphalt (asphalt’s black coloring hides some of the stain), both materials can be stained by automobile fluids. To prevent stains, make sure to clean up oil spills promptly and regularly wash your car. Also, place cardboard under your parked car to catch drips and prevent them from staining the driveway.
Vinegar and baking soda are effective at removing oil stains from asphalt driveways. Mix equal parts vinegar and baking soda, apply to the stain, then scrub with a brush before washing. For best results, allow the mixture to sit for a few minutes before scrubbing.
A few drops of muriatic acid can also clean a tough driveway stain. However, this is a strong solvent and must be used with extreme caution. Wear a mask and eye protection when applying muriatic acid and always test the product on a small area of your driveway before using it on the whole surface.
WD-40 is a combination of lubricants and can be used to remove oil stains from concrete driveways. Spray the soiled area of your driveway, let sit for a few minutes, then scrub with a brush and rinse with water.
For stains that can’t be removed with basic cleaning, try a commercial concrete stain stripper. Follow the manufacturer’s instructions for application and letting it sit before scrubbing with a stiff-bristled brush. For concrete or brick surfaces, a commercial concrete cleaner is a more aggressive approach and may need to be repeated before the stain is completely removed.
Regular cleanings with a garden hose or power washer prevent buildup that can lead to stains. In addition, routinely inspecting your driveway for leaks and addressing them promptly helps reduce staining. Finally, sealing your driveway protects the surface from damage and extends its lifespan.
Damage
While a cracked, pitted, and potholed driveway doesn’t automatically mean that your entire asphalt driveway is beyond repair, it does indicate that more extensive damage may be lurking underneath. Fortunately, most badly damaged driveways can still be saved with some form of asphalt patching. Surface patching is an excellent choice for asphalt that has moderately failed, as it’s a relatively quick and easy solution that requires only removing the top layer of the driveway to prepare it for new asphalt to be poured and compacted. Dig out patching is a more complex, yet long-lasting, option that involves digging up the failed section of your driveway and installing new asphalt from the ground up.
Other signs of aging asphalt that need to be addressed include depressions, bumps, and tire ruts that can impede vehicle travel and lead to additional damage over time. Keeping an eye out for these issues and regularly sweeping or blowing the driveway to remove debris, addressing oil and salt stains promptly, and having it sealcoated will help keep the pavement looking good.
If you have a concrete driveway, look for spalling. This is when the edges of the concrete begin to crumble, exposing the underlying aggregate. This is often a sign of improper installation when the concrete was poured, or it can be caused by repeated freeze-thaw cycles. Newer concrete repair materials are now available that can extend the life of your driveway by resurfacing it.
A faulty driveway is not only unsightly, but it can also be hazardous for vehicles and pedestrians. If you’re noticing cracks, depressions, or other forms of damage to your driveway, contact a professional for a repair estimate. Depending on the extent of your driveway’s damage, your contractor may recommend resurfacing or replacing the whole driveway, or a combination of these options.
Replacing your driveway is usually the most expensive repair option, but it’s necessary if you have more than moderate damage that has resulted in deep cracks, pits, or holes. Fortunately, this is typically the quickest way to restore the surface and improve your curb appeal.
