how to fill large cracks in concrete

Driveway cracks form in different shapes and sizes. Oftentimes, grabbing some gloves and going with a DIY approach can save both time and money when you’re looking to fix these issues.

With UNIQUE Paving Materials you can secure the right products to promote the overall longevity of your pavement. Approaching how to fill large cracks in concrete may seem like a troublesome task for homeowners, but it is achievable with products and tips designed to simplify the process. We’ll examine the methods for filling large cracks in concrete below.

1. When Looking to Fill Large Cracks in Concrete, Check the Weather and Conditions

If you live in an area where the weather is a little unpredictable – Cleveland weather, for instance, likes to surprise us with a range of elements – it is essential to look for a time when clear skies are expected before you start to fill large cracks in concrete.

Additionally, it is important to note that best results are produced on dry surfaces that are clean. If you are performing repairs after the winter months, be sure to wash salt and dirt out of any cracks for a quality outcome.

2. Obtain PPE to Fill Large Cracks in Concrete

When prepping and cleaning the surface to make it ready for repair, we recommend wearing goggles. This is done to prevent any dust or loose particles from getting in your eyes while cleaning. Gloves are also important when handling the fillers.

Protecting your skin can prevent any chemicals from entering openings in your skin, and additional steps to take would include wearing long sleeves and pants to ensure that minimal skin is exposed.

3. Know About Applications

After cleansing the surface and preparing yourself with the right PPE, it is important to note the following application features before filling the large cracks in concrete.

  • For the best results, know the shelf-life of your product. Many concrete repair tools are often useful for up to six months.

  • It is essential to let your filling job dry completely before allowing regular traffic to resume overtop of it.

  • Some jobs require multiple applications. This methodology can be effective for repairing cracks that have a lot of depth to them.
  • Some fillers may specify a certain range of temperature for optimal setting conditions, so it is important to note that as well.

4. Complete the Job with a Sealer

When you fill large cracks in concrete, it is important to allow everything to set properly. This means waiting for everything to dry completely and finishing with a quality sealer. A sealer is beneficial for many reasons and is known to protect surfaces from water, salt, dirt, and other contaminants.

What Causes Cracking in Concrete Driveways?

There are many causes of cracking in concrete. Some of them are due to factors you can control, and others aren’t. For this reason, it is important to be vigilant and treat any issues as soon as possible to promote the longevity of your concrete!

Here are the common causes of concrete cracking:

  • Changes in temperature and moisture – Temperature and moisture fluctuations can increase the chances of your surface experiencing thermal stress and cracking.
  • Aging and use – The more concrete is exposed to foot traffic, machines, and chemicals, the more it is prone to weathering and weakening, and therefore breaking. 
  • Lack of maintenance – Neglecting to repair minor cracks and sealing water out of cracks that are barely noticeable to the eye can lead to larger cracks over time.
  • Erosion – Water and chemical erosion can make your driveway more vulnerable to cracking and breaking. 
  • Settling – The ground underneath concrete is always prone to moving unevenly which can result in surface cracking. 
  • Improper drainage procedures – Getting water off your driveway as soon as possible prevents it from penetrating below the surface. Since concrete is porous, it absorbs this water and weakens the foundation. Therefore, it is important to ensure proper drainage and look out for puddling. 
  • Too much weight – Concrete is a sturdy foundation, but it isn’t meant to withstand extreme weight for long periods of time. With this in mind, it is vital to avoid leaving heavy machinery on your concrete driveway for extended periods of time. 

As we said above, some of these factors are well within your control while others are not. You can’t control the Earth’s settling or changes in temperature, so do your part by keeping those pools of water off your concrete and avoid leaving heavy machinery sitting on your driveway for extended periods of time. 

FAQs on Cracks in Concrete

How do I prevent cracks in my concrete?

It is almost impossible to prevent all cracks in concrete. However, by making sure you allow adequate curing time and conduct proper maintenance, you can increase the durability and lifespan of your concrete surface. 

When should I be concerned about cracks in concrete?

Starting by filling hairline cracks can reduce the number of larger cracks later on. However, cracks that are actively expanding are the ones most worth worrying about. In this situation, you might want to consult a professional to assess the safety of the area and develop a plan from there. 

How does regular maintenance extend the lifespan of my concrete?

Repairing minor cracks promptly, keeping heavy weight off your driveway for extended periods of time, and ensuring proper drainage means your concrete is less likely to form large cracks. Since these large cracks are the ones that result in the need for major repairs, conducting regular maintenance will minimize their development. And here’s another friendly reminder to use sealer, too!
