How to Use and Install Soil-Cement

Soil-cement is a mixture of Portland cement, natural soil, and water used to form a hard, semi-rigid paving surface.It is most often used in highways or as a sub-base for asphalt or other forms of paving, but it can also be used as a cheap stand-alone paving surface for driveways, sidewalks, patios, or garage floors.

Cement-Modified Soils (CMS)

A cement-modified soil (CMS) is a soil material that has been treated with a relatively small proportion of portland cement – less cement than is required to produce hardened soil-cement. The objective of the treatment is to amend undesirable properties of problem soils or substandard materials so that they are suitable for use in construction.


What is Soil Stabilization Soil stabilization is the permanent physical and chemical alteration of soils to enhance their physical properties. Stabilization can increase the shear strength of a soil thereby controlling the shrink-swell properties of a soil and, improving the load bearing capacity of a sub-grade.

Portland cement is comprised of calcium-silicates and calcium-aluminates that hydrate to form cementitious products. Cement hydration is relatively fast and causes immediate strength gain in stabilized layers (3). Therefore, a mellowing period is not typically allowed between mixing of the components (soil, cement, and water) and compaction.
