5 Different Types Of Concrete Cracks And Their Causes

Cracks in paved concrete surfaces are not something to be ignored. They can quickly get out of hand and cause significant damage to your paved areas if left unchecked. These cracks can also create a safety hazard for pedestrians or make it difficult for drivers to see hazards on the roadway.

This blog post will cover various concrete cracks and their causes so you can get them fixed before they get out of hand!

Porous Cracks

Porous concrete cracks are most commonly caused by the concrete being too wet when placed or cured. Once the concrete has been mixed, it needs protection from absorbing external moisture for proper hydration and curing. If this does not happen, then these porous concrete cracks can result in excessive bleeding of cement paste from the concrete. This bleeding can reduce the strength and durability of concrete dramatically, which is why it should be avoided.

Porous concrete cracks often occur in thin slabs because they tend to dry out quickly from evaporation or other causes before proper curing takes place, resulting in these types of cracks. They are also common when using rapid-hardening concrete mixes.

Expansion Concrete Cracks

Concrete expands in hot weather. This can cause the concrete to develop cracks, increasing over time and becoming a problem if left untreated. Expansion concrete cracks are most prevalent during the summer months when the air is hot and dry, causing the concrete to rapidly absorb heat from its surroundings. To avoid this, expansion joints are used to absorb the shock and prevent concrete cracking.

Heaving Concrete Cracks

Heaving concrete cracks usually occur in cooler, winter months when the concrete expands. Excessive moisture trapped on concrete surfaces over time causes heaving concrete. Heave can also be caused by poor drainage or water pooling around concrete slabs, causing frost to break up the surface of concrete slabs or pavements.

Settling Concrete Cracks

Settling concrete cracks are caused when there is a loss of support to the concrete slab. A crack forms in response to settling, or due to an uplift of concrete that has occurred over time. This type of concrete cracking can often be prevented by using expansion joints and appropriate foundation design. If you pour concrete over a poorly compacted base, the concrete may settle and cause a crack.

Concrete Cracks Due to Overloading

Concrete cracks due to overloading can be caused by heavy vehicles traveling over concrete slabs. Overloading forces the concrete below to expand causing a crack along its surface. Damages due to overload are more likely on concrete that has been weakened or deteriorated from previous cracking events like potholes or settling along the concrete.
