Void Filling
How to Handle Void Filling in Utah
Identifying the problem
What’s the first thing you think of when you see a hole in the ground or a cavity under a rock? I bet it’s some variation of “spiders”, “animal’s den” or “I’m not going anywhere near that!” I can’t say that those instincts are inaccurate but when it comes to cavities, or voids under a slab of your concrete, you need to:
- Know about it
- Check the severity
- Do something about it
Void filling is a big deal for the longevity of your concrete and possibly your home.
Understand your options
If you have noticed a void under your concrete you’ve probably faced the sick feeling in your stomach as you consider whether it is even possible to fix the problem without destroying, removing and repouring your concrete slab. There are a number of options any time you have a problem with your concrete, but if there is ever an alternative to the demo and replacement of concrete, and the weeks it takes to cure entirely, those options, like void filling, need to be explored.

At Landmark Lifting, we know how to handle void filling in Utah. We’ll come in and locate the cavities under your concrete, whether or not the slab has already started to crack, sink, or tip into the hole.
The Steps:
- Drill several dime-sized (⅝”) holes in your concrete

Void Filling FAQs
What are the common causes of voids in concrete?
Voids in concrete can form due to several factors, including soil erosion, poor drainage, and settlement of the underlying soil. Other causes may include shifting ground due to freeze-thaw cycles, tree root growth, or excavation activities nearby. Over time, these conditions can create air pockets or cavities beneath the concrete slab, leading to uneven surfaces.
What are the potential consequences of leaving voids unfilled?
Leaving voids unfilled can lead to serious issues, including further settling or sinking of the concrete slab, which can result in cracks and structural damage. This can create tripping hazards, reduce the lifespan of the concrete, and compromise the safety and aesthetics of the surface. Additionally, unaddressed voids may allow water to accumulate, leading to further erosion and degradation of the surrounding soil.
How can I identify if there are voids in my concrete?
You can identify voids in your concrete by looking for signs such as visible cracks, uneven surfaces, or depressions. If you notice areas where the concrete feels unstable or produces a hollow sound when tapped, these may indicate the presence of voids.
How long will the results of void filling last?
The results of void filling can be quite durable, often lasting for many years if the underlying issues are addressed and properly managed. However, factors such as soil conditions, moisture levels, and heavy traffic can impact the longevity of the results. It's important to monitor the concrete surface for any signs of settling or new voids, as prompt action can help maintain the effectiveness of the void filling service over time.
Are there any preparations I need to make before the void filling service?
Before the void filling service, it’s important to clear the area of any furniture, vehicles, or obstacles that may hinder access to the concrete surfaces being treated. You should also ensure that any landscaping or vegetation near the area is trimmed back to allow for adequate working space. Our team will provide specific instructions based on your property to ensure a smooth and efficient process.
