How Do I Fix Cracks in the Basement Floor?

If you have cracks on your basement floor, you should think about the different options you have available for fixing them. There are many potential options for people struggling with basement floor cracks. Some of these fixes work well, while others, unfortunately, don’t.

Which solutions work, and which ones should you pass over? Here are some of the commonly suggested solutions. 

Concrete Patch

A concrete patch typically goes over a crack to smooth it down and make it less noticeable from the outside. This concrete patch is typically DIY-friendly, which is probably one of the reasons it’s become so popular for people who have basement floor cracks.

The thing is, if you have a crack that’s indicative of a structural problem, a concrete patch isn’t going to do anything to fix it. It may harm your basement floor because you won’t be able to see whether the crack widens or stays the same. Don’t use this option unless a JES expert tells you to. 

Caulking

Caulk is a common option for many DIYers looking to cover over an unsightly crack or blemish. It can be useful in some situations, especially if something’s moved or come off not because of a structural problem, but because there wasn’t enough support for it in the first place.

However, as with a concrete patch, caulking can be very dangerous in this situation. You need to handle cracks in your foundation floor with the understanding that there’s probably something contributing to the problem. Any time you have basement floor cracks, don’t just cover over the crack unless a JES expert confirms it’s only a cosmetic problem. 

Replacement

If you have a significant series of cracks on your basement floor, you may have no option but to replace the concrete entirely. This is an arduous process that’s very expensive and time-consuming, but if you’ve ignored the previous cracks for so long that they’ve spread throughout the entire structure, a full replacement may be your only option.

It’s not ideal to replace the concrete instead of repairing it. This is typically a last-ditch way to save the home. The good news is, it’s almost always avoidable. If you get in contact with a JES foundation repair expert when you first start seeing the cracks, it’s more likely that you’ll be able to avoid this. 

Underpinning

JES offers many underpinning options for cracked basement floors and other foundation problems, especially those where the main problem is that your home is sinking. You may be able to take advantage of Helical Piers, Push Piers, or Slab Piers, depending on what suits your specific situation.

Everyone’s situation is different, but underpinning can be an effective method of supporting your home so it doesn’t continue to sink. In some situations, you may even be able to use it to lift a sunken home back to its initial position. Talk to a JES foundation repair expert if you think this might be viable for you.
