How to Fill Cracks in Concrete Walls: Everything You Need to Know

Concrete walls are incredibly durable and able to withstand an impressive amount of weathering. With that being said, concrete walls are inevitably susceptible to cracks over time. The good news is, there are various products available to homeowners and business owners that can allow them to fill and prevent cracks from forming, thus extending the lifetime and appearance of your residence or workplace.

This post will walk you through how to fill cracks in concrete walls, including the prep, prevention, and best products to use!

How Do Cracks in Concrete Walls Form?

If you notice cracks forming within your concrete walls, this is not typically an immediate cause for concern. Cracks often originate due to freezing and thawing, wear and tear over time, and occasionally as a result of improper pouring during the wall’s formation. There are different types of concrete cracks, as well as reasons why they may form, and these include:

  • Hairline cracks – These appear at the surface and should be repaired if they appear to be getting wider over time, are collecting dust or dirt, or are unattractive.
  • Shrinkage cracks – These cracks can occur during the curing process.
  • Structural cracks – These cracks will typically be a few inches wide and run through the entire slab of concrete. This type of crack warrants immediate attention.

How to Prep and Fix Concrete Walls

When it comes to how to fill cracks in concrete walls, correct preparation and application is important to ensure your repair lasts. Most importantly, you’ll want to ensure that the area you are filling is completely dry and free from dust and debris.

Next, you will want to work your way from the bottom of the crack to the top. Additionally, working in layers will ensure that deep-fill areas are entirely filled. For the best results, it is recommended to fill cracks in concrete walls when the outside temperature is between 55° and 75° Fahrenheit.
