Driveways are used for more than just driving cars; they also serve as convenient play areas and workspaces for millions of people involved in various projects.
Although a driveway has the lifetime of your home, various conditions can affect them to form cracks, spalling, heaving and other signs of distress over time. Most of them can be repaired, while some may require you to replace the driveway altogether.
While most driveways are either concrete or asphalt, you may opt for other options, including crushed gravel, stone, cobblestone and other patterned concrete pavers. And to help you make the right decision, we have included the pros and cons for each.
Besides, we will take you through the repair methods to help your concrete and asphalt driveway last longer. So, let’s start!
Even if there are several potholes or puddles in your driveway, you should consider repairing it first, which costs only a few dollars. For example, you need to spend around $2 per square foot while redoing an asphalt road, which includes the cost of gravel, soil prep and two asphalt coats.
If most of your driveway has subsided, heaved, or crumbled, replacing it is the best option. Due to extreme weather conditions or other factors, cracks appear on the surface, allowing water to seep inside and erode the driveway base.
So, if you can identify the cracks before they damage the driveway further, it’s safe to repair them. Otherwise, it’s better to replace it with a new one.
You can fix almost any crack on a driveway with cold-patch asphalt or concrete. Besides, you may even use some special materials depending on the type of driveway you have and the extent of cracks.
Firstly, clean any small cracks and plant holes using a water hose and spray weed killer to kill any plant growths. Follow it up by applying patching products to cover up those holes; the products to be used also depend on the size of a crack. For instance, you can use Ardex’s A-300, UGL’s Masonry crack filler and Quikrete’s Crack Sealer for a ⅜-inch crack.
However, use either Vinyl Concrete Patcher or Concrete repair for larger or deeper cracks. And if these products are not accessible to you, mix concrete and use masonry tools to apply it.
If there are deep cracks or large holes on your driveway, fill them up with gravel up to 4-inch and pour the concrete. Then, seal them with a magnesium float and use a broom or flat trowel to smoothen the surface—however, the larger the patches, the shorter their life cycle. So, you can cut short the job with a winter freeze and apply up to 30,000 psi of pressure.
Once the surface is patched, remove any existing spots using a specialty cleaner like Quikrete’s Concrete and Asphalt Cleaner. Seal the repair using UGL’s concrete sealer to keep the water out.
For concrete or an asphalt driveway, it’s crucial to call upon a reliable and professional contractor. In this regard, you can search for them under “asphalt and asphalt products” and “paving contractors” on the yellow pages.
Once you’ve selected a professional, make sure they guarantee the driveway to last for at least two years. You can also stipulate the payment schedule, where you pay one-third of the total when they take up the work and the rest when it’s completed. Also, add a clause where they are liable to make free repairs if the driveway develops cracks or holes within the guarantee period.
Apart from that, the contract should have other clauses related to the optimum use of materials and a standard way of work. This is so the driveway doesn’t get damaged irrespective of the weather conditions.
Many choices are available for plain or coloured concrete and acid or pigment staining. You also have stamped and coloured concrete that looks like stone with an exposed aggregate, allowing the top textured gravel layer to show through. There are many different options for concrete finishes that can add to your driveway and concrete’s overall design and durability.
Concrete driveways are durable and long-lasting. Depending on the subsoil preparation and weather, they last anywhere from 15 to 50 years, including their biannual repair. Also, the surface is smooth, making for easy snow removal and ideal for playing basketball.
The primary disadvantage of replacing your driveway with a concrete one is it needs almost a week to cure before you start driving on it. You need to repair the road more often to keep it optimal, as cracks are inevitable. Plus, you can’t relayer it, and its colour tends to fade over time.
Choices for asphalt driveways include pattern-stamped asphalt, plain hot-mix asphalt and acrylic polymer colours.
These are more resistant to cracks than concrete driveways, as they don’t flex much with ground movement. Plus, they are relatively durable, lasting for an average of 18 years, and you can apply another layer of asphalt on the existing layer if the surface gets damaged.
It isn’t easy to obtain clean and straight edges. Asphalt deteriorates in five years if it is not properly drained, and you must reseal it every two years to help it last longer. Additionally, plants can grow through the surface, therefore breaking it up.
Options include crushed granite, shale, concrete, limestone and various sized and coloured gravels.
An economical choice that offers excellent resistance to thaw or freeze. You won’t need to prepare any base for it; mix, dump and spread. And if gravels or stones scatter or compact, the surface would require redressing by adding a pea gravel coat, which is also not difficult.
Gravel and stone scatter easily, creating ruts. Also, with time, smaller stones sink, leaving larger ones on top, so it’s essential to redress them periodically.
Pavers come in several patterns and shapes, from unorthodox designs like anvil and trefoil to more traditional designs like keyhole, hexagon and bow tie. On the other hand, Cobblestone comes only in a more conventional rectangular shape.
Apart from the plethora of choices, a significant advantage is that they depend less on drainage and soil preparation. Cobblestones are very durable and last up to 100 years. Plus, replacing them is not much of a task.
These materials are relatively expensive, and their installation requires careful preparation and excavation. Furthermore, there are high chances that grass and weeds will grow between the wide cobblestone joints.
