Trying to pour high-quality concrete in Cedar Rapids , Marion, Iowa City, or North Liberty, Iowa can be involved if you don't take the time to understand what causes cracks and how to prevent them. Cracks in your pavement may seem unavoidable in many circumstances and may be impossible to avoid if you lack the skill to identify situations that may lead to severe cracks.
The following information is designed to help you better grasp some of the most common contributing factors to the cracked pavement in your driveway. Each section will briefly explain why these cracks occur and what you can do to prevent them. Most of the time, you're going to need professional help to assess this problem and to manage them for you reasonably and professionally.
Poor Selection of Materials
Many people may assume that concrete is all the same and that they can get the same results from a product no matter what they buy. That is simply not the case. Many types of cement and pavement materials are designed for more decorative items and will crack if you try to use them for driveways or other high-stress situations. You need cement that is designed specifically for the right purpose to avoid cracks on your driveway.
For example, you should find bags labeled “for construction use” to ensure your pavement is strong enough to withstand regular use. Just as importantly, you need to make sure that your temperature rating is at the right level to avoid complications. For example, some cement is rated for hot temperatures while others are rated for colder regions. Others are for more general use and adapt based on the temperature circumstances.
Adding Too Much Weight
Concrete is designed to be strong enough to withstand various elements but can become damaged if you add too much weight to its surface. This problem is typically common along the weaker areas, like the edges of a driveway, and will spread cracks through the surface very quickly.
Try to move heavy objects off of your pavement, when possible, or simply redirect concentrated heavy items away from each other. Adding too much weight on one spot can damage your driveway, but moving these items evenly across the surface may prevent many of these common issues.
Poor Joint Placement
When your pavement is poured, a multitude of joints will be cut into the surface. These joints are designed to give your driveway some room to grow and shrink and should keep your slab in good shape. However, cracks may appear around these joints if they are poorly cut.
Typically, you need to have joints that occur according to this formula: multiply the thickness of the slab in inches by 2-3 times to get joint location by feet. For example, if you have five-inch pieces, you'd need joints cut at least every 10-15 feet or so to keep the pavement secure.
Extreme Temperature Changes
Pavement is typically strong enough to withstand a multitude of temperature changes, but it may experience issues in extreme situations. For example, rapid temperature changes will cause expansion and contraction with the water in your pavement, which may cause cracks to appear.
Unfortunately, there isn't much that you can do to avoid this problem if you live in an area with regular temperature changes. However, you can prevent some of this damage by adding a sealant or sealcoat to the surface of your concrete. This step will minimize how much damage the sun and ice can do to your driveway.
Poor Drying Management
When your pavement is poured and adequately maintained, no cracks should occur in its surface. However, poor drying management could cause complications with how well your pavement settles. For example, the temperature may be a bit too cold, and your pavement may not dry as well as you'd hope.
Even worse, there may not be enough moisture in the cement, which can cause it to become too hard or brittle. As a result, the surface may start to crack right away as it dries. In this situation, you need to add more water to your mix and only pour on warm and dry days to avoid complications with your drying.
Adding Too Much Water in the Pavement Mix
One of the most significant contributing factors to cracked concrete is when you add too much water to the pavement mix. While water is a necessary part of the pouring process, excess water can water down the cement in your pavement and make it less secure. Though this wet pavement will eventually dry and become strong enough to support your vehicles, it will be more prone to damage than other types.
As a result, you need to make sure that the water added to your pavement is done so at a reasonable level. Typically, you need one bucket of water per every 10-pound bag of cement. Any more than that and your pavement will come out very watery. If you notice that the mixture has too much water, you can add more cement mixture – a handful at a time – to balance out its thickness a little better.
Ground Movement
Though you may think that the ground beneath your pavement is relatively stable, this idea is far from reality. The dirt and soil underneath your driveway are likely to go through frequent changes, such as heaving and settling, that can do a real number on your pavement and cause serious cracks.
One way to avoid this problem is to remove trees from your yard near the pavement. Tree roots often grow under your pavement and cause a variety of soil problems. You may also need to add more stable dirt underneath your driveway before you pour your pavement to avoid this complication.
