Filling The Concrete Voids

Sidewalk Leveling Sidewalk Raising

Are you tired of seeing sagging concrete on your property? If so, it’s important to take action before the problem worsens. Filling concrete voids can help prevent cracking and unevenness, which can lead to even bigger issues down the line.

But with so many different techniques and materials available, it can be difficult to know where to start. In this article, we’ll guide you through the process of filling concrete voids.

We’ll explore the causes of voids, why it’s important to fill them, and the different methods and materials used for this purpose. By understanding these factors, you’ll be better equipped to make an informed decision about how best to address any sagging or settling concrete on your property.

So let’s dive in and learn more about how to keep your concrete looking its best!

Causes of Concrete Voids

So, you may be wondering what causes those pesky voids in your concrete that require slab jacking or mudjacking to fill. Well, there are a few factors that can contribute to the formation of voids under your concrete slabs.

One major cause is soil erosion or settlement. If the soil beneath your slab is not compacted properly, it can shift and settle over time, creating empty spaces where your concrete used to be supported.

Another common cause of voids in concrete is poor drainage around your foundation. When water accumulates around the edges of your foundation, it can seep underneath and erode the soil below. This creates a gap between the ground and your concrete slab, which can eventually lead to sinking and cracking.

It’s important to address any drainage issues as soon as possible to prevent further damage to your foundation and ultimately avoid costly repairs down the road.

At Concrete Leveling Solutions, we know what needs to be done to get your concrete level and keep it that way for years to come, we use the best available technology and technics for concrete raising and leveling.

Our Process To Fill Your Concrete Voids

Importance of Filling Concrete Voids

It’s crucial to ensure that any gaps or empty spaces beneath your concrete surfaces are addressed promptly to prevent potential issues down the line. Here are five reasons why filling concrete voids is important:

  • It helps maintain the structural integrity of your property and prevents further damage from occurring.
  • Filling voids can greatly improve the appearance of your property by eliminating uneven surfaces and cracks.

  • Voids can lead to safety hazards, such as tripping and falling, especially in high traffic areas.

  • If left unresolved, voids can cause water damage to your foundation, which can lead to more expensive repairs in the future.

  • Fixing voids early on can save you money in the long run by preventing more extensive repairs later.

Don’t risk compromising the safety and stability of your property. By addressing concrete voids promptly, you’ll not only prevent further damage but also enhance its overall appearance and value.

Types of Materials Used for Filling Concrete Voids

When you’re dealing with gaps or empty spaces under your property, there are several materials that can be used to repair the problem and bring peace of mind.

One popular choice is polyurethane foam injection. This method involves injecting a two-part mixture of polyurethane foam into the voids underneath the concrete slab. As the foam expands, it fills any empty spaces and hardens quickly, providing a stable base for the concrete to rest on. Polyurethane foam injection is quick, efficient, and can be done in almost any weather conditions.

Another option for filling concrete voids is epoxy injection. This method involves injecting an epoxy resin into the gaps below the slab foundation. The resin hardens quickly, creating a strong bond between the foundation and surrounding soil. Epoxy injection is particularly useful when dealing with cracks or small holes in your concrete foundation as it can seep into even tiny crevices to provide reinforcement.

While this method may take longer than others due to curing time requirements, it provides long-lasting results that will give you peace of mind for years to come.

Methods for Filling Concrete Voids

Polyurethane foam injection and epoxy injection are two effective solutions for repairing gaps or empty spaces under your property. These methods involve injecting a specialized material into the voids, which expands to fill in the space and stabilize the concrete slab above.

Polyurethane foam injection is a popular choice because of its quick curing time and lightweight properties. The expanding foam can be injected through small holes drilled in the concrete, making it less invasive than other repair methods.

Epoxy injection is another option that involves injecting an adhesive material into the voids to create a strong bond between the slab and subgrade. Both of these methods provide long-lasting repairs that can prevent future damage to your property, giving you peace of mind knowing that your foundation is secure.

Maintenance and Prevention of Concrete Voids

To prevent future damage to your property, regular maintenance is key. Here are a few tips on how you can maintain and prevent concrete voids:

  1. Keep water away: Water is the biggest culprit when it comes to causing voids in concrete. Make sure that water doesn’t collect around or under your foundation by ensuring proper drainage and grading.

  2. Monitor soil conditions: Soil changes can cause shifts in the foundation and lead to void formation. Check for signs of soil erosion or compaction around your home, especially after heavy rainfall.

  3. Fix plumbing leaks promptly: Plumbing leaks can cause water to seep into the soil underneath the foundation, leading to void formation.

  4. Schedule regular inspections: Have a professional inspect your foundation regularly to catch any void formations before they become major problems.

By following these simple steps, you can ensure that your concrete remains strong and stable for years to come, saving you time and money in costly repairs down the road.

Benefits of Polyjacking

Cost Effective: Concrete raising is typically about half the cost of replacing the concrete. Ultimately, the cost of raising or stabilizing concrete is a direct reflection of how much leveling material the project will require.

 Time: Ready to use immediately.

 Clean Work Environment: No concrete or grout splatter and no wash down needed. No heavy equipment driving through landscaping.

 Smaller Holes: Polyurethane concrete raising requires nearly invisible ⅝” holes (size of a dime) drilled and the process calls for considerably fewer holes than traditional mudjacking. Minimal patchwork needed.

 Lightweight: The Polyurethane material will never lose density, is permanent and weighs only about two pounds per cubic foot, compared to traditional mudjacking material which weighs on average 100 lbs per cubic foot.

 Adaptable: Foamjection polyurethane foam is a top-of-the-line material, designed specifically for different concrete applications. It allows us to easily adjust our approach to your needs.

 Environmentally Friendly: Foamjection foam leaves the smallest carbon footprint in comparison to ALL other concrete lifting polyurethanes.

FAQ - Sidewalk Raising & Leveling

What is the cost range for slab jacking services?

Slab jacking services can cost anywhere from $500 to $1,500, depending on the size of the area and the severity of the problem. It’s important to get multiple quotes before choosing a contractor.

How long do the effects of slab jacking typically last?

Slab jacking can last for years, but it depends on various factors such as the quality of materials used, soil conditions, and maintenance. Regular inspections can help detect issues early and prevent further damage.

Can mudjacking be used for outdoor concrete surfaces such as patios and walkways?

Yes, mudjacking can be used for outdoor concrete surfaces like patios and walkways. This method involves pumping a sand-cement slurry under the slab to fill voids. However, it may have potential drawbacks such as future damage and lengthy curing time.

Is there a risk of the cementitious slurry seeping into underground pipes or drainage systems?

Yes, there is a risk of cementitious slurry seeping into underground pipes or drainage systems during mudjacking. This can cause blockages and costly repairs. It’s important to hire experienced professionals to minimize this risk and ensure proper placement of the slurry.

Are there any environmentally-friendly materials or methods for filling concrete voids?

Looking for eco-friendly options to fill concrete voids? Consider foam jacking. This process uses expanding foam injected into voids, reducing environmental impact and curing time. Plus, it won’t damage underground pipes or plumbing systems.
