Will My Concrete Slab Break If It’s Settling?

Your concrete slab is a lot more likely to break once it begins settling. Concrete is a reliable building material that has excellent compression strength, meaning that it does not lose its volume when under a lot of pressure. Unfortunately, this compression strength comes at the cost of its tensile strength, which is the reason why concrete slabs break when settling.

• Why It Breaks

Tensile strength refers to a material’s ability to handle pressure. It measures how much tension a structure is able to endure before breaking. If a concrete slab is able to evenly disperse the pressure throughout its body, it will have an easier time handling the weight. However, when slabs settle, they aren’t able to disperse the pressure evenly, causing them to crack.

This is more likely to occur in outdoor slabs that have to support heavy weights frequently. Your driveway is an obvious one, what with your heavy car putting pressure on the slabs whenever you drive in and out. The slabs on your patio are also likely to break if they have to bear the weight of heavy furniture and the people that use them.

• How To Prevent Breaking Your Concrete 

The more cracks on the slab, the harder it is to repair. Replacing a concrete slab can be an expensive ordeal, and it’s not as convenient as polyurethane foam injection repairs. Because of this, it’s in your best interest to want to preserve your concrete and keep it as intact as you can.

The moment you notice the settling, make sure not to place any weight on the slab or the slabs that surround it. For your driveway, this might mean parking your car elsewhere until the slab can be fixed. For your patio, you might have to remove the furniture or simply avoid sitting on it. Avoid walking on any settled pathways, and make sure to inform your family members of the change so they don’t end up breaking the slab.
