Soil Stabilization

Soil Stabilization Services

Soil stabilization is a powerful and cost-effective technology used by Gray & Son, a leading soil stabilization contractor in Maryland and surrounding areas. It is used when the soil available for a construction project is not suitable for its intended purpose. The soil is permanently altered, either physically or chemically, to meet a specific engineering purpose. Improvements include increasing structural integrity, controlling the shrink-swell properties of a soil and adding strength to almost any soil. Once the soil at your construction site is stabilized, it is protected against moisture issues so your project stays on track without unnecessary delays.

Soil Cement Stabilization:

  • Application rates are determined by the project’s geotechnical firm based on the properties of the soil and the moisture reduction required. Typical application rates by weight of the soil range from 4 percent to 10 percent, depending on the moisture content and soil type.
  • Delivered to the project site by a pneumatic tanker attached to a semi-truck. The material is off-loaded from the pneumatic trailer at the project site
  • Spread on the site as a dry powder by a variety of methods. Gray & Son, however, can accurately place the cement at the prescribed application rate and minimize dust by using our off-road, six-wheel Volvo A25C truck, which has been converted to include a 25-ton capacity material storage tank. A computer-controlled material spreader on the truck places the cement at the appropriate application rate.

Soil Mixing:

  • Accomplished using a variety of methods, including the use of Gray & Son’s Caterpillar RM-350B rotary reclaimer, which mixes the cement material into the existing soil to a depth of 12 inches. Several passes are made to ensure thorough mixing.

Soil Compaction:

  • Accomplished with a sheepsfoot, smooth-drum or rubber-tired roller. While the drying process is a gradual one that can continue over many days, it is not uncommon for heavy construction equipment to be introduced on the treated area the next day.

Geotechnical Evaluations:

  • Performed in conjunction with the installation to monitor moisture reduction and acceptance of the lift. If multiple treatment lifts are required, the process is repeated for each successive lift.
