Your driveway is a significant investment that impacts your home’s curb appeal and functionality. Depending on the severity of your driveway’s damage, repair or replacement may be appropriate.
Before proceeding with repairs, it’s important to thoroughly clean the damaged area. This will ensure that the repair materials adhere properly and that dirt doesn’t interfere with the process. Contact Driveway Repair Nashville for professional help.
Cracks in a driveway do more than just look unsightly, they can cause further damage to your concrete slab and allow water to seep in, which will exacerbate existing problems and lead to expensive repairs. While it is impossible to avoid all cracking, there are many things that can be done to minimize the damage and extend the lifespan of your concrete driveway.
First, make sure that any cracks are properly cleaned. This is important to ensure that the crack filler adheres correctly and stays on the concrete. It is also a good idea to use silicone-based crack sealants as opposed to the cheaper polyurethane-based ones. Silicone is much more durable against the harsh Southern Texas UV rays that can quickly dry and crack the caulking.
If your cracks are hairline or less than 12-inch, you may be able to repair them yourself with a basic patching product. Mix the material according to the manufacturer’s instructions and apply using a putty knife or trowel. When you are finished, sand the area to level it out and to match the appearance of the surrounding concrete. After the crack filler has cured, you should consider sealing the area with a waterproof surface sealant to protect the repair and prevent further infiltration of water and soil.
Larger cracks are more serious and indicate underlying structural issues that should be addressed immediately before the problem gets worse. These cracks are often caused by movement or settling of the concrete, which requires more extensive intervention, such as resurfacing or a complete removal and replacement of the damaged section.
Alligator cracks, which resemble a pattern of interconnected plates or scales, are another sign of more significant damage and should be repaired immediately. They can be caused by a number of factors, including poor drainage, heavy loads, and insufficient pavement thickness.
Attempting to repair these cracks by simply filling them with cement or other methods such as mudjacking will not fix the root issue and will only lead to further damage. Alpha Foundations offers PolyRenewal, a state-of-the-art polyurethane injection solution that addresses the most common causes of concrete deterioration and sinking.
Potholes
A pothole in your driveway not only looks bad, but it can also damage your vehicle’s suspension and tires. It’s also an invitation for water to seep into cracks and crevices, further deteriorating the surface and increasing repair costs. It’s important to deal with potholes as soon as you spot them.
Preventing potholes starts with understanding what causes them. The primary cause of potholes is water infiltration into asphalt cracks, which then freezes and expands with temperature changes, resulting in weakened asphalt that eventually collapses. Other causes of potholes include poor drainage, where water doesn’t flow away from the pavement, or base problems, where the underlying soil is unstable.
The good news is that potholes are relatively easy to fix, especially if you take preventive measures to address the root cause of the problem. For example, a thorough cleaning of the cracks with a pressure washer removes dirt and debris, allowing the patching material to bond well to the concrete.
You’ll also want to make sure the area surrounding the hole is free of extra moisture, which can lead to a premature failure of the new surface. Heating the hole also softens the existing pavement so that it can be reshaped and mixed in with the new asphalt. Compacting the repair with a tamper or your car’s tire also helps reduce the chances of the material becoming displaced.
If you’re unable to fix the pothole with a patching material, you might need a full replacement of the blacktop. Residential blacktop isn’t designed to withstand the weight of large trucks and other heavy vehicles, so the material can weaken or give way over time.
A professional assessment can determine whether a full resurfacing or replacement is necessary. To replace the blacktop, the old material will need to be removed and graded. The crown of the driveway will need to be reshaped and graded as well, which may require heavy machinery. A new base layer is added to the site, compacted and topped with a mix of gravel and fines. This material is then covered with a new surface of asphalt, which is applied with a hot mop and allowed to cool.
Crack Sealing
When cracks appear on a asphalt surface, a preventative treatment is the most efficient way to stop them from advancing. Similar to patching a hole in your jacket before it turns into a full-blown wound, crack sealing prevents these small gaps from spreading throughout the entire surface. By filling these cracks with a specialized flexible material, you effectively fortify your driveway against further damage and future repair costs.
A professional can evaluate the cracks, determine their cause and the best method of repair. They’ll also take into account the clients budget and their current needs. This helps them recommend a treatment that’s the most cost-effective in the long run.
In addition to keeping water from seeping into these voids and preventing further erosion, crack sealing also enhances the beauty of your driveway. It eliminates the unsightly look of large fractures and uneven surfaces, as well as trip hazards caused by them. A seal-coated surface also lasts 25-40% longer than untreated pavement, reducing the need for costly maintenance.
To get the most out of your crack repair, it’s important to thoroughly evaluate and prepare the affected area for the process. This involves meticulously cleaning the cracked area to remove any moisture or debris that may interfere with the bonding and curing of the sealant. This ensures a quality result that will withstand the test of time.
It’s also crucial to choose the right materials and equipment for your project. Hairline concrete cracks can be filled with standard pourable crack fillers or a concrete patching compound, while larger crevices and alligatored areas require more robust, rubberized products like GatorPave offered by SealMaster. A caulking gun, putty knife or trowel and a concrete sealer are additional essentials.
While some homeowners choose to DIY their driveway crack sealing, the best option is to hire a professional. They’ll have the specialized equipment, knowledge and expertise to ensure that your cracks are repaired properly and quickly for years to come. Professionals often provide warranties as well, which can offer peace of mind and reduce your stress about the longevity of the work.
Resurfacing
Resurfacing is a middle-ground option for driveway repair, providing a fresh appearance and increased durability while minimizing cost. The process involves applying a layer of material to the existing concrete, typically asphalt or cement, to address issues like cracks, discoloration, and uneven surfaces. Resurfacing is best for addressing surface damage that hasn’t yet affected the foundation, or for homeowners who want to minimize the expense and disruption of a complete replacement.
One of the most common signs that your driveway needs resurfacing is an overall worn out appearance. As the weather and heavy traffic cause your concrete to wear down, it can become discolored and dull. This can affect your home’s curb appeal and even impact its value. Driveway resurfacing rejuvenates the surface, restoring its original color and improving your property’s visual appeal.
Another common sign that your driveway is due for resurfacing is the presence of cracks and potholes. While these imperfections may not seem like a big deal at first, they can quickly turn into serious structural problems that require extensive and expensive repairs. Cracks and potholes can also lead to water seepage, which wreaks havoc on the foundation of your driveway over time. Resurfacing prevents further deterioration by covering these imperfections with a smooth layer of material that’s resistant to the elements.
Finally, driveway resurfacing is an excellent choice for addressing low areas of your driveway that can cause tripping hazards. Overtime, shifts in the soil and heavy vehicle use can cause sunken spots in your driveway that detract from its beauty and create a tripping risk for pedestrians and drivers alike.
As with any repair project, the extent of your driveway’s damage and your budget should be major factors in determining whether resurfacing or replacement is the right option for you. However, if you find yourself continually patching cracks or filling potholes, resurfacing might be worth the investment in the long run.
