"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 and/or control the shrink-swell properties of a soil, thus improving the load bearing capacity of a sub-grade to support pavements and foundations."

The process of chemically stabilizing soils involves the incorporation of different products such as cement powder, lime or fly ash into the poor, unstable soil. A geotechnical analysis of existing materials and project intentions determines the appropriate stabilization method and agent(s) used.
The powder is spread uniformly by a spreader truck and followed by a rotary mixer or reclaimer, which incorporates and blends the powder into the soil, sometimes with the addition of water injection to insure proper moisture content. Compaction, shaping with a motor grader and a final smooth roll, completes the process.
The finished product leaves our customers with a permanently altered, stable base. The soil is now capable of carrying increased loads, expanded traffic volume and greater moisture insensitivity to your project.
Cement soil stabilization is a highly compacted mixture of soil/aggregate, cement, and water. It is widely used as a low-cost pavement base for roads, residential streets, parking areas, airports, shoulders, and storage areas. It's advantages of great strength and durability combined with a low first cost to make it the outstanding value in its field. A thin bituminous surface is usually placed on the soil-cement to complete the pavement.
