What exactly causes voids under concrete and how do I fix them?
To begin with, voids under concrete are something which can not be ignored at any cost, and it is crucial to pay proper attention to the concrete so that you know about these voids. Concrete repair might be necessary as concrete crack or voids are something you do not want to have on your premises regardless of whether it is a house or a business.
It is so important to fill voids or make sure to undergo a crack repair/concrete patch is because if voids are left out and not filled then eventually, sooner or later the concrete will fail to hold the weight on top of it and it will most certainly break or fall inside the pit (although much if it depends on how big deep the void is or it the deepness of the pit). As a result of this concrete crack or void, not only are injuries to bystanders a threat, but the void beneath is the perfect place for animals like rabbits, mice, cats, and snakes to make their homes and stay inside these pits.
When do I need to fill the voids under concrete at my residence?
So it is clear that concrete crack repair is essential and can not be delayed, it is equally important to know the reason for this void because even if you hire a company and they do a concrete repair, it will just be a matter of time when there will be a void again. And the concrete floor would require some concrete crack filler or a concrete patch. There can be many various causes of voids, but the most common one is poor compaction of the material which was used to fill in the concrete cracks (concrete crack filler).
The second most common reason for voids is when too much water is seeping in the concrete through concrete cracks or when during winters the freeze and thaw cycles are high. If there is decaying material, this can also cause voids which will require a concrete crack repair or some void filling might be required depending on the void.
Common Void Filling Methods
There are many ways for a concrete crack repair including a method where polyurethane foam is injected into the concrete floor to fill in these voids. This concrete void filler will not only fill the void properly, but it will also give support to the upper part of the concrete and to some extent avoid future concrete issues however it all depends on the usage of the concrete. This method can be used when there is a minor issue however if settling has occurred meaning that the concrete has fallen into the void then mudjacking may be necessary. Mudjacking is a type of concrete crack repair where the concrete crack filler will not only fill the void but also lift the concrete and get it back to the surface which will result in an even flooring.
