Soil stabilization is the permanent physical & chemical alteration of soils to enhance their engineering properties. Stabilization increases both shear and compressive strength of soils & aggregates, improving their load bearing capacity to support pavements and foundations. It also helps to control the shrink/swell properties, reducing yearly pavement damage from freeze/thaw cycle. Stabilization can be used on a variety of soils including expansive clays, peats, silts and granular materials. Stabilized soils produce higher CBR values, increasing the load bearing capacity of a subgrade to the point that it can be incorporated into the structural design of a pavement’s cross section, reducing pavement and aggregate base thickness.

INCREASE PAVEMENT STRENGTH & STABILITYStabilization of soils results in a significant increase in compressive and shear strength, as well as reducing the ease with which moisture can move through pore spaces (hydraulic conductivity). This allows for resistance from pavement failure due to over-stress from applied axle loads, and the deleterious effects of the freeze/thaw cycle.
