Midwest - Subgrade Stabilization
Roads built over weak or moisture-sensitive soils often face long-term structural issues like cracking, rutting, and settlement. Treat the subgrade at the earliest stage of construction to improve load-bearing capacity for a more stable foundation. This lowers construction and repair costs with a longer-lasting paved surface.
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.
