Just a couple of years after you’ve moved into your new home, you started noticing suspicious cracks in the concrete of your driveway, walkway, and patios, not to mention in the foundation of your home. These are the most common types of cracks and the reasons why they ruin your concrete!

Shrinkage Cracks

Just a few hours after the pouring of concrete shrinkage cracks happen because, as the concrete dries, a change in moisture levels occurs. Since concrete and mortar are both porous materials and expand when wet, they also shrink after drying and irreversibly crack. That is a normal process and the reason why there are control joints between the concrete slabs. The problem is when random cracks meander across the slabs, caused by their poor layout.

Expansion Cracks

Cracks of this kind most commonly happen due to the weather conditions in very hot climates that cause the concrete to expand and push against surrounding obstacles.

Offset Cracks

The poorly consolidated soil underneath the concrete slabs creates a difference in slab elevation, which in turn forms a safety hazard in the shape of offset cracks.

Heaving Cracks

In climates with low temperatures, the cycle of freezing and thawing of concrete often happens, causing a change in the level of moisture present in the material. This process is also called “D-cracking” and looks like a series of cracks that travel parallel to the joint, caused by thawed ice.

Settlement Cracks

Settlement cracks often happen on concrete slabs placed over areas where utility lines or plumbing pipes extend.

Corner Cracks

As their name states, these cracks happen at the corners of concrete slabs, as well as at the intersections of joints and are typically caused by overloading the slabs. Among other reasons, this type of crack occurs because of curling caused by different temperatures between the top and the bottom surface of the slab, or warping, a process that happens when there is a moisture differential between the two surfaces.
