Deep Injection Soil Stabilization

Secure Your Foundation With Confidence Today!

Understanding the root causes of foundation and water problems is essential to safeguarding your home’s stability and value. Deep injection provides an innovative, cost-effective solution by stabilizing the soil beneath your foundation and addressing issues at their source. Let’s explore the challenges of unstable soil and how this method works to restore your home’s integrity.

Why Basement Water Issues Might Be a Deeper Concern

Water in your basement isn’t just frustrating—it’s a warning sign that your foundation could be at risk. Beyond the visible systems like damp walls, leaking cracks or pooling water, the real problem often lies deeper.


The soil beneath your foundation plays a critical role in stability and waterproofing. Soil erosion, voids and/or shifting ground could be the culprit behind your wet basement. Acting quickly can prevent worsening damage and reduce repair costs.


What lies beneath your foundation could hold the key to your water problems. Let’s explore these  issues below the surface and uncover their hidden causes.

Voids in Soil: 

Over time, soil beneath your foundation can shift, leaving empty spaces or “voids” that weaken the structure and allow water to pool. This can result in foundation cracks and water seepage. Fortunately, deep injection foundation repair can fill these voids, stabilizing the soil and preventing further damage.

Poor Soil Compaction: 

If the soil was not properly compacted during construction, it can lead to uneven settling. This results in shifting and unstable ground beneath your foundation. Soil stabilization techniques like deep injection can address this issue, compacting the soil and providing a solid base for your foundation.

Hydrostatic Pressure: 

Groundwater buildup pushes against your foundation, leading to cracks and leaks. This is known as hydrostatic pressure. Our foundation waterproofing methods, including deep foundation waterproofing, can address this issue by filling voids and displacing pooled ground water.

Persistent Water Intrusion: 

Even after waterproofing repairs, water seepage, leaks, and drainage problems can continue if unstable soil or voids beneath your foundation remain unaddressed.

Worsening Foundation Cracks: 

Expanding voids and shifting soil exert pressure on your foundation, leading to new or larger cracks in the walls and floors. This is a clear sign of foundation instability that requires immediate attention.

Uneven Floors and Foundation Settling: 

Sagging floors, misaligned door frames, and unlevel cabinets signal worsening soil erosion and foundation settlement. These issues often stem from unstable or eroded soil beneath your home.

Mold Growth and Musty Odors: 

Poor drainage and lingering moisture create the perfect conditions for mold growth, resulting in health concerns and unpleasant odors. Addressing soil stabilization can help eliminate these risks.

Why Traditional Methods Often Fall Short

When it comes to foundation repair, traditional methods are often associated with higher costs, longer timelines, and invasive processes that disrupt your property. While these methods have been around for years, they aren’t always the most efficient or cost-effective, especially when you want minimal disruption to your home and landscaping. Deep Injection Stabilization offers an innovative and affordable alternative that addresses these shortcomings, providing a quicker, less invasive, and more durable solution for stabilizing your foundation.


Before diving into the benefits of Deep Injection Stabilization, let’s explore why traditional approaches might not always be the best choice for your home.

Cement Pressure Grouting

Cement Pressure Grouting involves injecting a cement-based mixture into the soil to fill voids and improve soil density. While effective in certain cases, this method has several disadvantages:

  • Heavy Machinery: The use of heavy machinery can disrupt the property and surrounding landscape.
  • Messy and Invasive: Cement pressure grouting can be messy, requiring extensive cleanup and causing delays for the homeowner.
  • Prone to Erosion: Over time, the cement material can erode, reducing the longevity and effectiveness of the repair.
Helical Piers

Helical Piers are another common method of stabilizing foundations. These screw-like piers are driven deep into the ground to provide support to the structure. However, this method has its own set of challenges:

  • Invasive Installation: The installation process can be disruptive and messy, affecting your property.
  • More Expensive: This method tends to be more expensive than other foundation stabilization solutions.
  • Installation Limitations: Helical piers can only be installed along the edges of the foundation, leaving central areas unsupported and increasing the risk of voids forming beneath the structure.
  • Does Not Address Soil Issues: Most importantly, helical piers do not solve underlying soil problems, which could cause long-term issues for your foundation.
Push Piers

Push Piers are another widely used foundation stabilization method that involves hydraulically driven steel piers. However, like helical piers, push piers also have significant limitations:

  • Highly Invasive: This method is invasive and can cause considerable disruption to your property.
  • Does Not Address Soil Issues: Like helical piers, push piers do not resolve underlying soil conditions, leaving potential future problems unresolved.

Foundation Stabilization: Step-by-Step Through Our Deep Injection Process

At Suburban Basement Waterproofing, our expert technicians use advanced soil stabilization polyurethane foam. 


While similar to concrete leveling, deep injection stabilization focuses specifically on soil consolidation and filling voids beneath your foundation. Unlike concrete leveling, which re-levels slabs using lifting polymers, our structural polymer fills voids, strengthens the soil, prevents foundation settlement, and provides a lasting solution for basement waterproofing.


Our team offers free foundation and soil stabilization assessments for property owners in the following Michigan counties: Macomb, St. Clair, Oakland, Lapeer, and Wayne.

  • Comprehensive Assessment:

We begin with a thorough assessment to identify unstable soil and voids under your foundation. To ensure accuracy, we recommend a soil bore test from a geotechnical or structural engineer for the most detailed insight into your specific soil conditions. Based on the results, we’ll create a customized deep injection stabilization plan to address your foundation’s needs.


Note: Our foundation and soil-stabilizing foam solutions are tailored to meet the challenges of poor soil conditions. During the assessment, our foundation experts will determine the best process to address your specific needs:


One-Component Standard Soil Stabilizer: Ideal for permeating loose soil, strengthening and stabilizing it, while also preventing further erosion.


Two-Component “Deep Lock” Stabilizer: Perfect for stabilizing soil beneath structures with significant foundation issues, especially when dealing with greater depths or large-scale projects.

  • Precise Preparation:

Strategically placed small holes (about 5/8″) are drilled to access problem areas with minimal disruption, allowing for targeted soil stabilization.

  • Polyurethane Injection:

We inject specialized polyurethane foam into the soil. As the foam expands, it fills voids, compacts loose soil, and stabilizes the foundation, effectively preventing further sinking and shifting.

  • Continuous Monitoring:

Throughout the process, our technicians monitor foam expansion to ensure optimal soil stabilization and void filling, making sure the results meet our high standards for foundation stability.

  • Final Cleanup & Quality Check:

Once the foam has cured, we remove any excess material and clean up the area. A final quality check ensures the success of the deep injection stabilization process, providing you with peace of mind and a solid foundation for the future.

Explore commonly used terms in basement waterproofing and foundation repair, specifically related to our Deep Injection Soil Stabilization services.

Unstable soil refers to ground material that lacks the strength or stability needed to support structures effectively which can result in serious foundation issues if not addressed with soil stabilization.

The slow removal of soil caused by water, wind, or environmental forces, often leading to the formation of voids beneath foundations. These voids can compromise the foundation's stability and increase the risk of structural damage.

The force exerted by standing or accumulated water against a structure, such as a basement wall or foundation. When hydrostatic pressure becomes excessive, it can lead to cracks, leaks, and water infiltration, compromising the structural integrity of your home. Proper stabilization and waterproofing measures are essential to mitigate the effects of hydrostatic pressure and protect your foundation from damage.

The gradual downward movement of a foundation due to soil compaction, erosion, or changes in soil composition. This process can result in structural issues such as cracks in walls, uneven flooring, and misaligned doors or windows.

The capacity of a structure to endure its intended loads and environmental stresses without experiencing failure, excessive deformation, or compromise. Ensuring proper soil stabilization is essential for maintaining the structural integrity of your foundation and home, as unstable soil can lead to settlement, cracks, and long-term damage.

A technique used to stabilize foundations by injecting specialized materials, such as polyurethane foam, into empty spaces or gaps beneath a structure. These voids often form due to soil erosion or foundation settlement over time. This process enhances structural integrity, prevents further settling, and ensures long-term foundation stability.

Small gaps or air pockets within the soil beneath a foundation, which can weaken its overall stability over time. These microvoids can hold pockets of water that can further contribute to erosion and potentially seep into your basement.

The ability of soil or a structure to support weight or loads without failing or shifting. In the context of foundation stabilization, the load-bearing capacity refers to how much weight the soil beneath a foundation can safely hold. Enhancing the load-bearing capacity of the soil is essential to prevent settlement and ensure the long-term stability of your foundation.

Involves the study of soil, rock, and other earth materials to ensure safe and stable foundations. Geotechnical engineers are certified to evaluate the ground beneath and around foundations and provide a detailed soil analysis.

A test completed by extracting soil samples from the ground to analyze their composition, stability, and load-bearing capacity. The test identifies weak or unstable soil conditions that lead to foundation issues. The results guide advanced soil stabilization methods, including the deep injection process, to ensure effective foundation repair and long-term structural stability.

A set of techniques designed to improve the strength, load-bearing capacity, and durability of soil, ensuring it can effectively support foundations and other structures. Soil stabilization prevents foundation settlement, minimizes movement, and provides long-term stability, protecting against structural damage caused by weak or shifting ground. Advanced methods, such as deep injection, offer highly effective solutions for stabilizing unstable soil.

Polyurethane foam is a strong, expandable material commonly used in deep injection techniques to fill voids, stabilize soil, and reinforce foundations. Known for its flexibility and durability, this foam provides an effective solution to foundation issues caused by weak or shifting soil. It is also a preferred method for addressing foundation settlement and erosion while ensuring long-lasting stabilization.

A specialized foundation stabilization technique involving the injection of dense grout material into loose or weak soil. This method compacts the surrounding soil, enhances its load-bearing capacity, and prevents further foundation settlement. While traditionally associated with cement-based grouts, advanced polyurethane (poly) grouts—like those employed by Suburban Basement—offer superior performance in soil compaction and structural reinforcement.

A soil stabilization technique that involves injecting grout into the spaces between soil particles to enhance its strength and durability while preserving the soil's natural structure. This method is commonly used to improve load-bearing capacity and reduce the risk of settlement in weak or loose soils. Traditional methods would involve the use of cement mixtures, however poly grouts are less invasive to inject and stabilizes without the risk or erosion.

Every foundation is unique, and our goal is to provide solutions tailored to your home’s specific challenges. Deep injection soil stabilization is a powerful method for addressing soil-related issues, and it’s just one of many services we offer that can be used independently or in combination to meet your needs.
