Cracked concrete is not only unattractive but can also become dangerous the longer you leave the cracks alone. Cracks can grow over time and have the potential to cause serious harm to cars and pedestrians on your property. Not to mention, they are a great place for grass and weeds to grow. You don’t want to delay concrete crack repair.
Do you have a cracked driveway? Understand what causes cracks and how concrete caulk can repair and improve the look, value and safety of your property.
There are five main reasons that can cause your driveway to crack, including:
• Plastic shrinkage. Concrete is made up of cement and water. As the concrete hardens and the water evaporates, the concrete shrinks. Too much water will lead to too much shrinkage, causing the concrete to crack. That’s why concrete cracks are frequently seen within the first 30 days.
• Fast drying. Ever wonder why concrete cracks when drying? Concrete that dries too quickly can cause crazing and crusting. Concrete crazing (a network of hairline cracks) occurs when there is either too much or too little moisture. If you have stamped concrete, crusting can occur when the pattern is pressed prematurely.
• Change in weather. Temperature and moisture are the main culprits behind cracked concrete. When the humidity and temperature change, the concrete will shrink and expand. So, when the temperature and humidity rise, your concrete will expand, and when the weather drops, your concrete will shrink.
• Heaving and settling. Ground movement can cause concrete to crack and break. Heaving results from growing tree roots or a dramatic freeze and thaw cycle that causes the ground to push up on the concrete and crack. The opposite is settling, which is when decaying tree roots or when the soil collapses like from water damage cause the concrete to sink and crack.
• Overload. While concrete is very strong, applying too much weight can cause your concrete to crack from pressure. The thickness of your concrete will determine how much weight it can hold without cracking.
The bad news is cracked concrete, unfortunately, can’t be prevented in most cases. However, the good news is you can repair the cracks.
Caulking is a great concrete crack filler that will keep the appearance of your driveway looking as good as new and help raise your property value. It will also prevent injury to you and pedestrians as well as damage to your vehicle. While concrete caulk won’t prevent new cracks from appearing, it will ensure that existing cracks won’t cause any damage to you or your cars.
Additionally, if you need concrete leveling, you should also think about caulking. While procedures like concrete leveling with polyurethane will raise and realign concrete slabs, you it’s important to caulk after it’s done in order to seal cracks, make your driveway smooth and keep it from sinking for a long time.
From driveways and sidewalks to patios and seawalls, Mr. Level has extensive experience fixing cracks in concrete. While many believe broken or cracked concrete needs to be replaced, you can usually repair it for much cheaper with concrete caulk.
