Soil Stabilization is the modification of soil to enhance the physical properties to meet an engineering purpose. Soil Stabilization improvements include increasing the weight bearing capabilities, tensile strength, and overall performance of subsoils, sands, and waste materials in order to strengthen surfaces for roadways, parking areas, site development projects, airports, and many other uses when soil is not suitable for construction. Stabilization can be used to treat many sub-grade materials such as expansive clays and granular materials, among others. The soil stabilization process is achieved by using a variety of additives, such as clay, fly-ash, lime and other blends.
