Some types of cracks just occur, and the best you can do is to try to prevent them. It has also been observed that sometimes problem arise in spite of taking precautions.

Plastic shrinkage cracks

One of the most common reasons for early cracks is plastic shrinkage. These cracks are only a hairline and are hardly visible. Although it is a hairline, it spreads the complete thickness of the slab. They develop just after few hours after the slab has been poured and the project is completed. One of the main factors that result in this type of cracks is mixing the concrete too wet.

Expansion cracks

Another big cause for cracks in concrete driveways is expansion. During hot weather, a concrete slab can enlarge or expand as it gets hotter. This can further result in great stress on a slab. Due to this effect, concrete may push against any object that comes in its way. The resulting force can lead to a crack.

Cracks due to crowding

Heaving is also one of the main causes of developing cracks in the concrete. It happens because of freezing or thawing cycles. During such periods the freezing ground can lift up to many inches, and then may go down again when the ground thaws. If the slab does not have enough space to move, it will crack. If there are large tree roots, they can cause the concrete to heave.

Cracks due to subsidence

You may also find cracks in your concrete driveway if a large tree is removed from near a concrete slab. The buried roots will decompose resulting in an empty space. This will result in the settling of ground and the concrete to crack. Settling is most common over trenches where the useful pipes and plumbing pipes are buried.

Cracks due to excessive weight on top of the slab

Another crucial reason which results in cracks is excessive weight on the top of the slab. Although it is a very durable material, concrete has some load boundaries. When ground water penetrates the concrete, it causes the soil to become soft, and too much weight on the slab can put pressure on the concrete, pressing it down. Property owners who use driveways for keeping large vehicles or dumpsters are more likely to find this type of cracks. Even driving heavy vehicles on the corners of the slab can result in a crack.

Cracks due to early drying

You will find some concrete cracks that are similar to spider webs or dismantled glass. They are fine surface cracks that occur when the top region loses moisture too quickly. They are so smooth that there is no way to repair them.
