Cement & Lime Stabilization for Paving Projects

When the native soil is too soft or unstable to support pavement or slabs. Stabilizing the subgrade is often more reliable than working around poor soil.

Cement and lime stabilization are soil improvement techniques that enhance the strength, stability, and performance of existing soils. Cement is commonly used to increase strength and stiffness, while lime helps improve the workability and engineering properties of suitable clay-rich soils.

Soil stabilization may be needed when the existing soil is weak, highly plastic, moisture-sensitive, or unable to provide adequate support for the planned construction. It can help improve subgrades for roads, parking lots, industrial facilities, and other pavement projects.

Cement stabilization is generally used to increase soil strength and stiffness, particularly in suitable granular and cohesive soils. Lime stabilization is often effective for clay-rich soils, helping reduce plasticity, improve workability, and control moisture sensitivity. The best treatment depends on soil composition and laboratory testing.

The process typically involves evaluating the soil, preparing the site, spreading the appropriate stabilizing agent, mixing it thoroughly with the soil, adjusting moisture content, and compacting the treated material. Proper curing and quality control help ensure the stabilized layer meets project specifications.

Soil stabilization can improve bearing capacity, reduce soil plasticity and moisture-related movement, increase durability, and create a more reliable pavement subgrade. Depending on site conditions and project design, it may also reduce the need to excavate and replace unsuitable soil, helping control construction costs.
