Soil Stabilization: How This Service Benefits Multiple Structures

Soil does more than cover the ground or support plant life: it serves as the base for many of the structures we rely on every day. From building foundations to critical infrastructure, stable soil is a necessary support system. When that stability is compromised through loss or shifting, the results can be costly: settlement, cracking, water leaks, and even structural failure. In this article, we’ll dissect how stabilizing soil stabilization can benefit multiple structures, including commercial, residential, and even industrial.

How Unstable Soil Negatively Impacts Surrounding Structures

Unstable soil undermines the integrity of the structures it supports. When soil shifts, erodes, or loses density, the consequences can escalate from minor disruptions to severe structural damage. Here are some of the issues that come with soil instability:

• Settlement: Soil instability can cause foundations, slabs, and other structures to sink. Even minor settlement can lead to secondary concerns such as cracks, uneven or bowing floors, doors and windows that no longer close properly, and rocking concrete slabs. These problems create safety hazards, may increase energy costs, and result in expensive repairs. In commercial and industrial settings, trip hazards may also expose property owners to liability.
• Cracks: Cracks aren’t just unsightly nuisances, they signal underlying structural distress. Cracks can occur in culverts, manholes, and bridges, as well as building walls and foundations. They are often the result of soil loss and void development, freeze thaw cycles that cause soil to expand and contract, or erosion brought on by heavy rain, floods, or leaking utilities.
• Leaks: When soil shifts away from manholes, storm drains, culverts, or sewers, joints can separate or structures can crack. These openings allow water to escape, which accelerates soil loss and void development, compounding the problem.
• Structural Failure: If ignored, soil instability can culminate in catastrophic failure, including sinkholes, collapsing pavements, and compromised buildings, all of which pose severe safety and financial risks.

How Soil Stabilization from USG Can Benefit Surrounding Structures

The prevention of soil loss or movement can help protect nearby structures. So how can these risks be addressed? Through polyurethane soil stabilization from USG. Here’s how it works:

1. The soil and nearby structures are examined through a variety of means, including but not limited to geophysical testing, soil samples, CCTV camera inspections, SUE Support locates, and other forms of assessment, depending on project needs.
2. After a thorough assessment, a plan is formulated for polyurethane injection. Locations of injection are plotted, then holes are drilled into concrete, floors, or soil. Through these holes, injection rods may be placed, depending on how deep the polyurethane needs to go.
3. Through the holes or rods, polyurethane is injected. The polymer moves in its liquid form into the soil, following the path of least resistance into areas of weakness or voids.
4. The polyurethane reacts and expands in the soil, forming a highly dense polyurethane soil matrix. This matrix fills the gaps left in loose or voided soil, reestablishing soil connectivity and holding the soil firmly in place.
5. After injections are complete, the area is assessed again to ensure the project meets specifications.

This process not only stabilizes the soils, but can also mitigate the issues being experienced by surrounding structures. Here’s how the service benefits those structures:

• Concrete Slabs: Soil stabilization can stop the movement, settlement, or cracking of concrete slabs above or on the adjacent to treated soils. Whether it’s a sidewalk, parking lot, driveway, roadway, or any other slab of concrete, soil stabilization helps solve the root cause that leads to their issues: soil movement.
• Infrastructure: Polyurethane soil stabilization can help infrastructure! Just like concrete slabs, the process of stabilization stops the soil movement that is detrimental to the structure. In some cases, the same process can also be done to seal infrastructure from experiencing leaks or inflow and infiltration.
• Buildings: Whether a residential home or commercial building, soil stabilization can help stop the soil loss occurring down below. The process may mitigate foundation damage, structural damage, or bowing floors. In some cases, just like with infrastructure, the same polyurethane injection process can be performed as a method of foundation repair or concrete floor leveling.

Soil stabilization is more than a preventative measure. It’s a solution that protects infrastructure, preserves safety, and reduces costly repairs. By addressing soil movement at its source, polyurethane injection ensures that the structures above remain stable and reliable for years to come.
