Deep Soil Foam Injection
Few things are more demoralizing to a homeowner striving for beautiful curb appeal, a backyard oasis and a safe property than sunken concrete slabs. They look unkempt, create tripping hazards and are a favorite spot for weeds to grow. The sunken areas also collect water, which can cause the concrete to sink further.
Voids under the concrete usually cause these sinkholes. These voids can result from erosion beneath the slab or unstable soils. Previous foam injection systems addressed the subsurface failures, and now Advance Concrete Lifting and Leveling offers Alpharetta deep soil foam injection for deeper levels and sinkhole repair throughout Atlanta.
What Does Deep Soil Foam Injection Do?
If sinking concrete is caused by more than just subsurface damage, repairing the subsurface will only partially fix the problem. Without a way to reinforce deeper into the soil, there is no way to stabilize underlying conditions. Deep soil foam injection is considered a significant upgrade from previous foam injection systems.
Deep soil foam injection works similarly to how a tree’s roots support soil structures. Extensive root systems snake in different directions, crossing over themselves multiple times and binding the dirt between them. This stabilizes the soil and prevents erosion. Deep soil foam injection works the same way. It repairs unstable soils and increases soil load-bearing capacity by flowing past the larger voids and into the small cracks and openings, creating solid areas where weak points once existed. With a stable underlying structure, the concrete is then raised at the subsurface level for a strong, long-lasting repair.
Deep soil foam injection is the perfect soil stabilization, void filling solution for:
- Lake wall repair/River wall repair
- Pool deck repair
- Foundation lift
- Foundation void repair
- Factory floor void repair
- Filling/stabilizing dangerous sinkholes
- Stormwater Collection Structures
Alpharetta Deep Soil Foam Injection
Using an engineering tool called a dual mass dynamic cone penetrometer (DCP), Advance Concrete Lifting and Leveling can test the soil. We do this to determine its density and ensure we give the substrate the exact strengthening and stability it needs, all the way down to 15 feet. After the carefully controlled deep soil foam injection process, we retest to confirm the operation was successful and the soil is solid. The inert foam does not react with its environment or leach any chemicals into the ground, making it a safe and effective solution for your concrete problems.
Deep Soil Foam Injection: An Efficient Alternative to Pressure and Compaction Grouting
For contractors considering pressure grouting or compaction grouting for soil stabilization, Deep Soil Foam Injection offers a highly effective alternative. Instead of pumping traditional cement or grout underground, Advanced Concrete uses high-density polymer foam that expands to fill voids and stabilize shifting soil. This modern solution provides the same level of support while being faster, less invasive, and quicker to set.
With fewer environmental disruptions and a streamlined installation process, Deep Soil Foam Injection can be the perfect alternative for soil stabilization projects that require both efficiency and durability.
What’s the Difference Between Regular Polymer Injections and Deep Soil Injection?
At Advanced Concrete, we offer two primary types of polymer injections: regular polymer injections and deep soil injection, and while both are designed to stabilize and lift concrete, they target different depths and types of soil problems.
Regular polymer injections are used primarily for lifting or leveling concrete slabs. These injections are applied directly under the slab or within the first few inches of soil. This technique is ideal for addressing surface-level issues such as minor settling or voids just beneath the concrete.
On the other hand, deep soil injection goes much further into the ground, targeting weaker soil layers several feet deep. Most deep soil issues can be fixed at depths between 2 and 6 feet, but in more severe cases, injections may need to reach down to 15 to 20 feet to stabilize the soil. This process is particularly useful for projects where the underlying soil is unstable, causing significant structural concerns.
To inject the polymer deep into the ground, we use steel pipes that allow us to deliver the material exactly where it’s needed, ensuring comprehensive stabilization.
How Do Our Experts Determine the Depth of the Problem?
Determining the depth and severity of weak soil layers often requires specialized testing. One such tool we use is the Dynamic Cone Penetrometer (DCP), which measures the resistance of the soil to penetration. This test correlates with the California Bearing Ratio (CBR), providing a reliable indication of the soil’s strength and stability.
The DCP works by driving a cone into the ground at various levels, and the resistance is measured to assess the soil’s capacity to bear loads. Based on the test results, we can identify the exact depth of weak soil and determine how far down we need to inject the polymer to ensure proper stabilization.
