Boost Load-Bearing Strength With Engineered Polymers
Stabilize diverse subgrade soils with proven polymer performance.
Start with the best for the best results. Midwest’s polymer-based, high-performance Subgrade Stabilization System improves underlying strength and stiffness even in poor soils. Whether weak, moisture-sensitive, or variable, the Midwest polymer binder formulation blends into subgrade soil during new construction and before base installation. These polymers coat soil particles to form a flexible yet durable matrix that resists water, cracking, and deformation under load. This stands in sharp contrast to lime or cement, which only performs well within a narrow soil range.
Midwest Subgrade Stabilization improves roadbed support for paving and infrastructure.
Every new road or infrastructure project requires a stable foundation. Whether it is an access road, haul route, or city street, it all starts with a strong base beneath the surface. Midwest’s proprietary, polymer-based systems stabilize weak or variable subgrade soils during the earliest phase of road or site construction. These treatments typically reach depths of six inches or more, making them the deepest of any of our stabilization systems.
Our polymer subgrade stabilization formulation is blended into native soils using standard equipment to enhance foundation strength, reduce moisture sensitivity, and prepare the roadbed for base layers and pavement.

THIRD-PARTY PROVEN PERFORMANCE
Midwest always supports any claims with real-world proof. Our subgrade stabilization solutions have been independently tested and proven for:
- Increased Strength — Achieved unconfined compressive strength (UCS) up to 500+ psi
- Greater Durability — Handled over twice the strain capacity of cement solutions while staying less brittle and more resilient
- Superior Protection — Reduced reflective cracking in asphalt overlays
- Freeze-Thaw Resilience — Maintained mechanical performance through freeze-thaw and wet-dry cycles, confirming superior all-weather reliability
- Broad Versatility — Enabled thinner pavement sections without sacrificing support
- Unmatched Flexibility — Substantiated in the field to perform across variable soil types
Ordinary Methods Have Been Bypassed By Midwest
More soil compatibility for less risk and better results.
Traditional stabilization methods often involve tradeoffs that limit performance. Recognizing these constraints, Midwest reimagined subgrade stabilization from the ground up — delivering a solution without compromise.
Whereas lime is only effective in clay-rich soils and cement works best in granular materials, Midwest’s proprietary polymer system is engineered to perform across a wide range of soil types. It also offers faster curing, eliminating the delays typically required with traditional stabilizers.
Beyond compatibility and curing, performance longevity sets Midwest apart. While lime and cement create rigid, brittle bonds prone to moderate or severe cracking, Midwest polymers form a flexible matrix that resists cracking under stress and movement.
These advantages extend to environmental and safety performance as well. Lime and cement are associated with high CO2 emissions and pose health risks due to their caustic, dust-generating properties. In contrast, Midwest’s non-caustic, low-dust solution reduces environmental impact and requires only minimal PPE.
Setting the New Standard in Subgrade Stabilization
Midwest polymers are designed to stabilize a wide range of native soils. Engineered flexibility prevents reflective cracking, while fast curing reduces downtime and accelerates project schedules. High-performance subgrade stabilization has proven successful for subgrade preparation to create a strong foundation for newly paved roads, as well as road foundations in large infrastructure projects that include industrial, military, and energy sector construction.
Our system represents a smarter alternative to cement and lime for new construction, stabilizing subgrade soils for paved roads and infrastructure projects. Midwest engineered polymers are tailored to soil chemistry and project needs to make it possible to treat weak, moisture-sensitive, or variable soils through early-stage roadbed processes.
The Midwest polymer-based system stabilizes subgrade soils while supporting sustainability goals with a low carbon footprint along with reduced environmental and safety risks.
- Improves load-bearing strength and stiffness in poor soils
- Reduces settlement, rutting, and deformation under traffic
- Limits moisture infiltration and susceptibility to frost
- Creates a resilient, consistent working platform for base and pavement layers
- Reduces future cracking by absorbing subgrade movement
- Extends the life of pavement and chip seal by strengthening the base
