What Causes Floor Cracks?

Most homes will have floor cracks at some point. A variety of situations can cause cracks to appear, yet not all call for foundation repair. Some are minor and pose no cause for concern. Others need immediate attention to prevent further damage. The reasons that lead to cracking will help determine whether your foundation is at risk.

Foundation Shifts and Soil Movement

Homes take years to settle on their foundations, which is a normal process. Usually, a foundation shift is different because soil causes movement beneath the floor. The larger the soil movement, the larger the cracks will be.
Movement occurs when soil expands and contracts according to the amount of rainfall. When soil saturates, it expands, pushing against floors and house foundations. When soil dries out, it contracts. This wet-dry cycle causes cracks in concrete floors.

Substandard Concrete or Poor Workmanship

Concrete floors and foundations are a combination of cement and water. If the mix didn’t have the proper proportions, the mix is substandard. This will cause serious problems. Faulty design, such as inadequate slab thickness also cause floor cracks. Steel reinforcement is also a must. Hairline cracks keep getting bigger and bigger until they cause severe foundation problems.
Tree Roots

Even if you don’t have any large trees or bushes near your home, their roots can travel far. Large roots can push up against concrete slabs causing them to crack.

Generally, floor cracks that are bigger than the width of a credit card are cause for concern. Contact Perma Built Inc. for reliable Tulsa foundation repair.
