Asphalt Versus Concrete

With proper installation and routine maintenance, both asphalt and concrete can last for several years. So, the paving material that you ultimately choose will depend on several factors, including your budget, particular paving application, regional climate, location, intended use, and much more. It is important to speak with a licensed and experienced Indianapolis Indiana paving contractor who can help you understand the best options for your pavement installation or repair project.

When you are focusing solely on budget, the cost of asphalt versus concrete may play an important role in your final decision. Both materials may pose both advantages and disadvantages depending on your paving needs.

Asphalt Cost

In the paving industry, asphalt is one of the most economical choices because it is a very inexpensive material. For this reason, you often see roads and driveways paved with asphalt. In comparison, concrete is typically more expensive and requires a higher level of routine maintenance.

You can expect asphalt cost anywhere between $1 and $5 per square foot installed, while concrete has the average cost of $3 to $10 per square foot.

These prices depend on several factors, of course, and will vary depending on retailer, grade, quality, and volume. One of the most determining factors will be the size of your paved lot. The larger the lot, the more money it will cost to install, regardless of paving material.

Comparing the Two

It is difficult to compare the cost without first identifying all of the factors unique to your paving project and/or needs. As a general consensus within the industry, it is suggested that asphalt is typically cheaper, but only initially.

Over time, asphalt will require some routine maintenance, such as seal coating, or minor repairs, which can add to the annual cost of paved asphalt. You can expect paved asphalt to last anywhere between 10 and 30 years, while most concrete paved surfaces last between 20 to 60 years.

How to Repair Concrete Cracking and Minor Damages

Posted on July 30, 2021 by admin

The concrete in and around your commercial building plays an important role in your property’s curb appeal, and therefore, it’s overall value. If your concrete parking lot, drive paths, sidewalks, curbs, bollard posts, steps, and ramps are starting to show signs of damage, it is wise to resolve these pavement issues before they can take a turn for the worst. Overtime, minor concrete damage progresses into major damage, which can cost you a lot of time and money to repair.

So, to subside concrete wear and tear, and prolong the life of your commercial pavements, be sure to address minor concrete damage as soon as they form. The most common type of minor concrete damage is cracking. Fix this as they form to prevent more damage from developing.

Continue reading to learn which products and supplies you need, as well as how to repair concrete cracks, both working and non-working.

Commercial Concrete Crack Filling Indianapolis 317-549-1833

What You Need to Repair Concrete Cracks

The most common and recommended products for repairing concrete cracks include vinyl concrete patchers, concrete patching compounds, polymer modified structural repair fillers, and advanced polymer concrete crack sealants. You can find all of these products online or at your local home improvement store. There are many brands to choose from, but a popular choice for all is Quikrete. Always clean concrete thoroughly and remove any debris prior to applying any of these products.

Working and Non-Working Cracks

Before you start applying products all over the place, you must first identify the type of cracks you are repairing. Concrete cracks are either working cracks or non-working cracks, which are also referred to as moving and non-moving.

► Working Cracks in Concrete – Working cracks form deep and wide or have one side that is taller than the other. These cracks continue to grow larger and threaten other nearby structures. To repair working cracks, apply an advanced polymer concrete crack sealant.

► Non-Working Cracks in Concrete – Non-working cracks do not change, nor seem to pose a threat to any nearby structures. They appear in the form of thin, shallow crevices in pavement. If a non-working crack is more than a ½ inch in depth, use a polymer modified structural repair filler.

Other Types of Concrete Damage

Aside from working and non-working cracks, it is important to identify any other types of concrete damage before getting started with your repairs. Look for shallow divots or chips, as these will require a different type of concrete repair product than moving and non-moving cracks. In fact, to repair these kinds of trivial concrete damages, you will need to use a vinyl concrete patcher or patching compound. You will also need a trowel to apply these products smoothly.
