Tell-Tale Signs of Basement Wall Cracks

Several issues can lead to cracked basement walls. Let's reveal the root causes that are especially prevalent during this problem and their relation to your home's foundation.

Repaired and Renovated Basements

Have you ever done any repair or renovation work in your basement that required wall drilling? For instance, you may have a drilled basement wall if you have a new sewer, electric, or gas line. Such tasks often pose stress points that become the reason for wall cracks. It can lead to weaker concrete and cracking in the corners of windows that angle off the edge.

It's a common occurrence that can be frustrating for any homeowner. A foundation repair Tennessee professional will typically check this as a first spot for cracks during a foundation inspection and help correct the issue.

Poor Foundation Construction

It is important to use the right materials during the foundation construction of any property. This will help prevent foundation problems due to cracks that occur in the future when the concrete ages or weakens. If high-quality building materials are not used, the entire foundation of your home is compromised and could fail.

The finishers sometimes run out of concrete when a foundation is being poured. If you wait for more concrete to arrive, the water can seep into your foundation, forming cold joints. This can disrupt the overall process and result in an incomplete foundation. So, quick action is a must!

Too Wet or Dry Soil is a Concern

Sometimes, the soil under a basement might get drenched, causing the footings to lower. The footings are the structures that support basement walls, and when these footings drop, they can crack the walls.

Plus, soil that lacks moisture can cause wall cracks. The ground underneath your basement can dry out and shrink during a drought. As a result, basement walls shift outward and cause the footings to settle. In this case, your foundation will sink, stretching the basement walls and making them crack.

Expansion and Contraction

The water poured into the concrete is very necessary when mixed to make a solution, and it will naturally expand when wet and contract once it dries. If the temperatures fluctuate or the foundation experiences changing moisture levels can cause concrete to expand and contract. Over time, the growth and shrinking often lead to cracks that need control.

Gutters & Downspouts Issue

Gutters must be clean from vegetation, and ensure downspout drains are pointed away from your home. Checking the gutters regularly can help ensure that they are not clogged, nor are any leaks found that can cause water to overflow near the foundation and damage it.

Improper Drainage System

Whether an older or newer home, you may experience wall cracking issues due to inadequate landscape sloping and an improper drainage system. The soil around your foundation should be properly sloped to direct water away from the foundation.

Improper drainage raises the soil's moisture content and creates hydrostatic pressure against the basement walls and crawl spaces. The more pressure applied to the walls, the more likely they lead your foundation to shift and crack. Often the problem is unnoticed until cracks start to develop in the structure. Foundation repair experts can inspect the drainage system and provide a perfect solution to drain the water properly.
