• Understanding Foundation Cracking in Building Construction

    October 27, 2024 | By Kenza TMT Steel Bars

    Every building needs a strong and stable foundation for it to be durable because the foundation is like the backbone of your entire house. If something goes wrong with the foundation, the rest of the structure will face serious issues. You might have heard of homeowners being scared because they saw cracks in their foundations. Even though you don’t need to panic when you see cracks, it’s not something to ignore either. Let’s break down the concept and try to understand how you can prevent foundation cracking and what to do if it happens. But first,

    What are Foundation Cracks?

    They are exactly what they sound: cracks that form on the foundations of your home. Even though foundations are made from very strong concrete, they can still develop cracks over time. While some cracks are harmless others often indicate serious structural problems that need immediate attention. The problem is understanding which cracks are just signs of normal settling and which are dangerous. Understanding the type of foundation helps you make this distinction. So let’s take a look at the types of foundation cracks you may come across.

    Types of Foundation Cracks

    Hairline Cracks

    They are fine line-like cracks you can see soon after you build the foundation. They are often caused when the concrete shrinks slightly as it dries. They are usually harmless and don’t cause any serious problems. But it is always good to keep an eye on them to see if they get bigger.

    Vertical Cracks

    These are cracks that run up and down the foundation. They are the most common type of foundation crack and can develop over time because. If your cracks are small, you need not worry much. However, if water seeps in, it can cause significant problems.

    Horizontal Cracks

    These cracks are the most dangerous types of foundation cracks. They run sideways along the foundation and often indicate that they are experiencing serious pressure from the soil outside. You need to repair them immediately because they can compromise the integrity of your home.

    Stair-Step Cracks

    They are mostly found in brick or block foundations. They look like a staircase and usually occur because the soil shifts or settles unevenly. Even though they don’t always mean structural damage, they can still be a cause of water leaks or further deterioration. 

    What causes Foundation Cracks?

    There are some natural causes for foundation cracks, and others are a result of poor construction practices or lack of maintenance.

    If the soil you build on is not compacted properly, the foundation may settle unevenly and cause cracks.

    The soil can also shift or expand due to changes in moisture.

    If there is excess water around your foundation for whatever reason, be it heavy rain, melting snow or poor drainage, the water can exert pressure and lead to cracking. Even if the leak is small, water seeping through cracks can weaken the foundation over time.

    Concrete can expand and contract as the temperature changes, causing it to crack.

    Even though it may not look like it, roots can cause a lot of damage. As the root grows and expand, they can push against your foundation, leading to cracks.

    Sometimes, foundation cracks happen simply because the foundation was not built properly. It could be because they used low-quality materials in the foundation or that it was not allowed to cure properly. In such cases, cracks can form as soon as the house settles.

    Natural disasters like earthquakes, floods, or landslides can all put stress on the foundations. Even if they don’t cause visible damage, they can still create hairline cracks in your foundation. Also, read Understanding the Types of Cracks in Concrete: A Comprehensive Guide
