Soil Cement Stabilization

Cement modified soil used to improve the properties of the subgrade soil.

Improving Soil Properties by Adding Cement

Cement Modified Soil (CMS) is created when substandard soil is treated with a small amount of portland cement. Depending on the type of soil and the properties desired, the proportion of portland cement can be modified to achieve the engineering objectives. The improved soil material is typically only slightly harder than the original soil but the improvement in other mechanical propertied can significant.

Cement Modified Soil is a common solution for pipe bedding, slope protection, and subbase for pavement. Cement Modified Soil has saved soil that is otherwise unsuitable for pavement support.  The methods to turn poor soil into CMS are similar to Full Depth Reclamation or cement stabilization except that less cement is used.  The 2% and 3% cement contents common in CMS do not coat all the particles and thus do not form a monolithic mass.  Instead, the cement improves the engineering properties of the resulting soil.

Benefits of Using Cement Modified Soil

CMS saves time, money, and resources by using the in-situ soil that is otherwise unsuitable.

CMS reduces traffic, noise, and community disruption by eliminating up to 40 truck loads of material shipping with each truck load of cement.

•  Improves the engineering properties of soil by mixing smaller amounts of cement than are needed to produce monolithic soil cement.
