Cracks in your basement are a common problem, and when doing basement remodeling, basement crack repairs must be done before finishing the basement. Addressing basement crack and water seepage in basement issues will help avoid any possible water problems and damages. Protect your entire home from any cracks in the interior and exterior parts of your home. Common basement floor cracks can be found on crawl spaces due to water leaks or high moisture levels. 

Foundation crack repairs are a handful, especially when the crack is severe. Basement crack repair is best done by a professional to seal basement floor cracks and ensure that your basement remodeling will have an excellent finish. 

How to detect basement wall cracks

Hydrostatic pressure is the usual cause of cracks in the floor and foundation walls. Usually, pressure from the natural movements of soil surrounding the foundation can cause the concrete to break, crack or split. Whenever it rains, or soil absorbs water, it generates moisture and pressure towards the foundation walls. Settling soil and frost movements create even more pressure, often resulting in cracks.

Locate the top of your foundation wall

Go to the top of your basement foundation wall and check where the basement wall is. Usually, foundation cracks and larger cracks can be found at the foundation wall. 

Scrape out the dirt

Scrape out the dirt using a metal wire brush to expose the basement wall foundation. Scraping out the dirt will help you determine if it’s a basement wall crack or just form lines. Check if it’s a narrow crack, diagonal crack, or horizontal crack when you spot one.

Check for hairline cracks

Once you have cleaned the basement foundation wall, inspect and check for hairline cracks. Some hairline cracks are short and unnoticeable. Make sure to carefully review the crack if it’s a basement wall crack by checking the basement’s inside. If it corresponds to a basement seepage, it is most definitely a basement wall crack.
