# When Is a Foundation Beyond Repair? > A foundation needs to be in really bad condition before it's beyond repair. Most foundations can be repaired. _Brian Dalinghaus · 2023-08-07_ --- If you're searching for information about when a foundation is beyond repair, don't hit that back button because you've landed on the right page. In this article, we'll review the difference between structural and non-structural foundation cracks, foundation repair solutions, when a foundation is beyond repair and more. ## What Is a Foundation Problem? When we say a house has a foundation problem, we're referring to any issues or defects that compromise the structural integrity of the foundation. Since the foundation bears the weight of the entire house and transfers it to the ground, any problems can lead to serious consequences, such as structural damage, safety hazards, and decreased property value. ## What Causes Foundation Problems? The most common cause of foundation problems is differential settlement, or when a foundation settles unevenly. Differential settlement puts enormous stress on a foundation, and if it isn't promptly corrected, it can lead to severe structural damage. So, the question is, what causes differential settlement? Various things, including the following, cause differential settlement: - **Improper foundation construction:** If the foundation wasn't built to adequately support the structure's weight or was constructed on unstable soil, it may begin to settle into the ground unevenly over time. - **[[sign:foundation-repair/expansive-soil|Expansive clay soil]]:** Soil with a high percentage of clay expands and contracts with changes in moisture levels. This back and forth, swelling and shrinking, creates movement under the foundation, which can lead to differential settlement. - **Erosion-prone soil:** Some types of soil are prone to erosion. If this happens, voids can form beneath the foundation. If the foundation settles into the voids, there will be differential settlement. - **Tree roots:** Trees with extensive root systems planted too close to the foundation can cause serious trouble when the roots push against the foundation's walls, work their way into cracks, and cause issues with the soil under the foundation. Keep trees at least 15 feet away from the foundation. ![Foundation settlement, differential vs. uniform: a house before settling, a house that has settled evenly, and a house that has settled unevenly](/assets/blog/when-is-a-foundation-beyond-repair.jpg) ## Common Signs Your Home's Foundation Might Have a Problem The most common signs your home might have a foundation issue include the following: - **The most obvious sign of foundation problems is the appearance of cracks in walls, floors, and ceilings.** These cracks are not just cosmetic but can indicate significant structural issues. Usually, vertical cracks are less of a concern than horizontal ones. We'll have more to say on cracks in just a bit. - **Another symptom of foundation problems is doors and windows that stick and are difficult to open or close.** This happens because the foundation is uneven, causing everything to be out of plumb. - **Uneven flooring is another sign of foundation problems.** When the foundation isn't level, the floors will become uneven. This can cause tripping hazards or even damage to furniture and appliances. ## Structural vs. Non-structural Cracks When it comes to foundation cracks, it's essential to understand that not all cracks are created equal. There are two categories of foundation cracks: structural and non-structural. Understanding the difference between the two can help homeowners determine whether they need to take immediate action or if the crack can wait for repair. ### Structural Foundation Cracks Structural foundation cracks are the more serious of the two. Examples of structural foundation cracks include cracks that are wider than ¼ inch, horizontal, diagonal, or stair-step cracks, and cracks that are accompanied by other signs of structural damage, such as uneven floors or doors that don't close properly. ### Non-structural Foundation Cracks Non-structural foundation cracks, on the other hand, are smaller and less concerning. Examples of non-structural foundation cracks include vertical hairline cracks that are less than ¼ inch wide. They often occur due to shrinkage during the concrete curing process and are not a threat to the structure's overall stability. ![Structural vs. non-structural foundation cracks: a structural crack wider than 1/4 inch beside non-structural hairline cracks under 1/4 inch](/assets/blog/when-is-a-foundation-beyond-repair-2.jpg) ## The Good News Is Most Foundation Problems Can Be Fixed The good news is most foundation problems can be fixed, and rarely is a foundation beyond repair. Various repair methods can be used to fix foundation problems, including underpinning using push or helical piers, [[solution:foundation-repair/carbon-fiber-reinforcement|carbon fiber wall straps]], and wall anchors.

When a foundation is determined to be beyond repair, it typically means that the structural integrity of the building has been compromised to such an extent that it wouldn't make sense economically to repair the foundation. This can occur for various reasons, including a catastrophic natural disaster or a long-neglected foundation problem. In other words, a foundation needs to be in **_really_** bad condition before it's beyond repair. As we noted above, most foundations can be repaired. Determining when a foundation is beyond repair requires a thorough inspection by a qualified engineer or contractor. They will evaluate the extent of the damage, the underlying causes, and the potential risks associated with repairing or replacing the foundation. ## How to Prevent Foundation Problems Since most foundation problems are caused by water, homeowners can go a long way toward preventing issues simply by controlling groundwater around the foundation. Here are some ways to do that: - **Keep your gutters clean and debris-free.** When gutters become clogged, water can overflow and seep into the ground around the foundation, causing problems. - **Install downspout extensions.** These will direct runoff away from the foundation before release. - **Re-grading the yard around the home** can also help prevent foundation issues. Ensuring the ground slopes away from the house rather than toward it allows groundwater to flow away from the foundation. - **Installing a drain tile system** can be an effective preventative measure for foundation problems. This involves excavating around the foundation and installing perforated pipes that redirect water away from the foundation. ![Ways to improve drainage around a foundation: regrade the yard, extend downspouts, clean gutters, move thirsty plants away, and install a drain tile system](/assets/blog/when-is-a-foundation-beyond-repair-3.jpg) If you're concerned about your home's foundation and wondering if it's beyond repair, contact us today to schedule a foundation evaluation.
