Why Does Concrete Crack?
What are the Main Causes of Cracking and Breakage in Concrete Floors?
Most common factors of concrete cracks include, but aren’t limited to:
- Water evaporating too quickly from the surface of the concrete – moisture is one of the leading factors of concrete floors cracking or breaking. Moisture mitigation products from Bone Dry are the best way of preventing more cracking or breakage happening in your concrete floor!
- Poorly-compacted soil underneath the concrete causes shifting – soil beneath concrete floors has the potential to shift around and move over time, or water pooling underground can either raise or lower the land beneath the concrete.
- Drying concrete shrinking due to temperature changes – a wide range of temperatures and weather patterns can affect the way cement dries
- Corrosion of steel underneath concrete – Oxidation of reinforcing steel bars beneath the concrete can cause cracks to form in the cement.
- Pressure from exceeding the weight limit – cracks can form in concrete due to having too much weight on it for extended amounts of time. Cars generally aren’t heavy enough to form cracks, but larger vehicles like semi-trucks can cause breakage in concrete surfaces if they cause pressure for a long enough time.

How Do You Prevent Concrete Cracking?
Cracks in concrete can happen for a variety of reasons, but exposure to heavy weights, moisture penetration, and a wide range of temperatures are the leading causes of it. There are so many factors to consider for when cracks occur in concrete, but the best way to prevent it is to take every possible precautionary measure when pouring it. Some of the precautions to take include:
- Structural design – Contraction, expansion, and isolation joints need to be constructed at reasonable intervals beneath reinforced concrete. Proper width and spacing is required to making concrete flooring as strong as possible.
- Mixing materials – Cement mixtures are strongest when not contaminated with foreign materials, like clay or dirt. A larger amount of aggregate in the cement plays an important role in crack prevention, and because of that, shrinkage can be reduced with the smaller amount of water in the concrete mixture.
- Placement – A properly compacted subgrade (the ground beneath where the cement is being poured) is important for preventing cracks occurring in concrete. A careful inspection of the subgrade, as well as an evaluation of the climate in which the cement is being poured, is essential in preventing cracks forming.
- Finishing and curing – Curing cement as quickly as possible helps make it stronger and reduce the risk of cracking. A dehumidifier can be used to encourage concrete to dry more quickly since it can reduce the dew point of the hair surrounding the cement.
Want to Prevent Cracking? Bone Dry Products Can Help!
Bone Dry concrete moisture mitigation products are water-based, penetrating sealers which produce a waterproof barrier deep within your concrete floor, helping you prevent cracking and breakage within the cement. Epoxies and other sealants aren’t as versatile as Bone Dry sealers, and can be up to four times as expensive – Bone Dry products are much more affordable and easy to apply.
