Like asphalt, concrete is a durable material excellent for sidewalks, curbs, dumpster pads, and so much more. Concrete holds up exceptionally well to the elements. However, over time, even the toughest concrete surface will crack.
Common Causes of Concrete Cracks
Cracking can be the result of one or a combination of factors such as drying shrinkage, thermal contraction, subgrade settlement, and applied stresses.
- Drying Shrinkage: When the water used in mix design evaporates, concrete cracking can occur.
- Thermal Contraction/Expansion: This occurs as the result of temperature changes.
- Subgrade Settlement: When the underlying soil condition is poor or there is a change in soil moisture content, cracking can occur.
- Applied Stresses: Outside forces, such as building load, earth load, hydrostatic pressure, or heavy equipment can cause cracking.
According to the Concrete Foundations Association (CFA) of North America, “there are two guarantees with concrete. One, it will get hard and two, it will crack.” When this happens, it not only detracts from the overall look of your property, but it can become a safety hazard, as well.
Unfortunately, cracking cannot be prevented, but it can be significantly reduced or controlled with proper repairs.
