Why Do I Have a Cracked Slab?

Cracks in a concrete slab foundation can be caused by shrinkage, settlement or even expansive soil.


Concrete Shrinkage
It’s a fact of life, concrete shrinks. These types of cracks typically show up shortly after the concrete’s poured and before it’s had time to fully dry. Most of the time, shrinkage cracks aren’t cause for concern however, if your home is older than 6 months and these cracks start to show up, you could have a foundation problem.

House Settlement
If the ground you home sits on is no longer able to support the weight, you’ll start to notice cracks in your concrete slab. You may even be able to see these cracks outside of your home in the bricks or around the steps. If your cracked slab is caused by settlement, then your home needs additional support to prevent additional damage.

Expansive Soil
Clay soil is a type of expansive soil. It expands more than other soil types when wet, and shrinks more when dry. This dramatic movement can be the source of a cracked slab. And if you live in an area that freezes, then frost heaves will also create a foundation problem.

Can I Fix My Cracked Slab?

Fixing your cracked concrete slab foundation isn’t a DIY project. A concrete patch, caulking or sand packing are nothing more than quick-fixes which cover up the slab cracks. They don’t address and repair the cause of the slab cracks: your settling foundation or expansive soil.
