Soil Stabilization & Deep Foam Injection

---

     Soil movement is one of the most common causes of concrete failure, foundation settlement, pavement cracking, and structural displacement. When the ground beneath a slab becomes weak, eroded, or poorly compacted, the structure above begins to shift — sometimes slowly over years, other times suddenly after heavy rain or seasonal freeze–thaw cycles. Our soil stabilization and deep densification services address the true source of these issues by strengthening the subsurface and restoring load-bearing capacity where it is needed most.

     Using engineered polyurethane resins designed for geotechnical applications, we inject structural foam deep into weak zones below the surface. As the material expands, it compresses loose soils, fills voids, and creates a dense, uniform support layer that significantly improves the soil’s ability to support weight. This method is clean, controlled, and highly effective in stopping settlement, preventing washouts, and stabilizing areas affected by water intrusion, erosion, or poor original construction practices.

     In many cases, this process can be used as an alternative to piering or helical piers, especially when the cause of settlement is weak soils rather than a structural failure of the foundation itself. Deep injection can strengthen the subgrade across a broader area, provide uniform support, and stabilize layers of soil that traditional piers may not address. While each situation is unique, soil densification often provides a less invasive, more cost-effective solution that corrects the problem at its true source — the ground beneath the structure.

     Soil stabilization is essential for both residential and commercial structures because the health of the soil determines the long-term performance of any foundation, slab, pavement, or structural component. Our approach is ideal for homes, driveways, garages, basements, seawalls, industrial floors, municipal infrastructure, roadways, and large commercial facilities. Whether the issue began during initial construction or developed over time, strengthening the soil prevents continued damage and protects your investment.

Common scenarios that benefit from soil stabilization include:
• Weak or loose soils that cannot support existing loads
• Erosion or washout near seawalls, utilities, or structural slabs
• Subgrade failure beneath pavements, sidewalks, and roadways
• Settlement caused by poor compaction during construction

     Weak soil rarely improves on its own. Left unaddressed, it often leads to recurring settlement, cracking, and expensive structural repairs. Our deep injection process provides a long-term solution by targeting the exact depth and location of the problem. The material reacts quickly, even in wet conditions, making it an ideal choice for environmentally challenging or water-affected sites.

     One of the most valuable aspects of our service is the ability to pair stabilization with Dynamic Cone Penetrometer (DCP) testing. This testing method gives real-time insight into soil density and bearing strength before and after injection. By collecting actual field data, we can measure improvement, identify problem layers, and ensure the final soil structure meets the demands of the project. DCP validation is especially valuable for municipalities, engineers, and commercial property owners who require documentation of load-bearing improvement.

     Our soil stabilization process begins with a full assessment of site conditions, settlement patterns, drainage behavior, and soil type. Once the areas of weakness are identified, injection points are strategically placed to deliver the resin to the proper depth. As the material expands, it strengthens the soil matrix, fills voids, and locks surrounding soils into a denser, more stable formation. This process is precise, minimally invasive, and completed without excavation or heavy equipment. Once stabilized, the area can often be returned to service the same day.

     Choosing the right contractor for soil stabilization is critical, because this service is more than just lifting concrete — it requires an understanding of soil mechanics, structural loading, water movement, and site-specific environmental factors. Our team uses professional equipment, engineered materials trusted by DOTs and geotechnical professionals, and a process built around accuracy and long-term performance. We provide honest evaluations and clear recommendations, including when stabilization is or is not the appropriate repair method. Our goal is always to create a more stable, safer, and longer-lasting foundation for your structure.

     Wisco Concrete Solutions serves clients locally and across state lines, including work in high-water environments, coastal areas, industrial sites, municipal projects, and residential properties. From small stabilization issues beneath a garage slab to large-scale subgrade reinforcement for commercial or municipal infrastructure, we bring the same precision and commitment to every project. Wherever the job is located, we are equipped to travel and provide the technical expertise required to resolve complex soil failures.

    For property owners, engineers, municipalities, and contractors seeking a reliable, non-invasive, and data-proven method to strengthen the ground beneath their structures, our soil stabilization service offers a dependable solution that improves safety, performance, and long-term value.

     Soil stabilization strengthens weak, loose, or eroded soils so they can properly support concrete slabs, foundations, pavements, and structures. When soil loses density, the surface above begins to settle or crack. Stabilization restores load-bearing capacity and prevents future movement.

     We inject expanding structural resin into targeted soil layers. As the foam expands, it compresses loose soil, fills voids, and forms a denser, stronger supporting base. This method increases bearing capacity without excavation or heavy equipment.

     In many situations, yes. If the cause of settlement is weak or eroded soil—not structural foundation failure—deep injection can stabilize and densify the ground enough to eliminate the need for piers. Every project is evaluated individually to determine the best approach.

     We use tools like Dynamic Cone Penetrometer (DCP) testing to measure soil strength and identify weak or collapsible layers. This gives us precise data before and after injection, ensuring the treatment is applied exactly where it’s needed.

     Yes. The polyurethane resin we use reacts in wet conditions and is ideal for areas with groundwater intrusion, erosion, or saturated soils. It displaces water, fills voids, and stabilizes the surrounding ground.

     Structural-grade polyurethane foam does not break down, absorb water, or decompose. Because it creates a long-term, moisture-resistant support system, soil stabilization is considered a durable, lasting solution for both residential and commercial applications.

     Soil stabilization can correct subgrade failure, uneven slabs, voids, washouts, roadway settlement, utility line erosion, seawall soil loss, and unstable foundations caused by poor compaction or long-term soil movement.

     No. The process is minimally invasive and requires only small injection points. There is no excavation, no heavy machinery on the property, and most projects are completed in a few hours with minimal surface disturbance.

     Almost immediately. The foam cures within minutes and reaches full structural strength quickly, allowing homeowners, engineers, or facility managers to return the area to service the same day.

     Yes. We provide stabilization solutions for roadways, bridge approaches, airports, industrial floors, water treatment facilities, utilities, seawalls, and municipal infrastructure. We also travel out of state for specialized or large-scale projects.
