Soil Remediation

The soil at various industrial and commercial sites-and in brownfield redevelopment locations­-often requires remediation, best achieved by means of solidification and stabilization.

 

Solidification, or soil drying, generally refers to the process of changing a highly flowable, compressible, or semi-solid soil to a material having greater cohesion and compressive strength. This process is often required so a waste material can be placed in a landfill. Stabilization generally refers to the addition of a chemical agent to the soil in order to encapsulate organic contaminants and to reduce their mobility.

 

Cement products can be mixed with the soils in-situ or blended with the soils in a pug mill or other mixing device. The treated soil can then be either left on site and compacted or removed from the site and taken to another location, depending on local and/or governmental regulations.

 

Lafarge cementitious materials, including portland cement, NewCem®-brand slag cement, fly ash, CKD, and blended cements, can be part of an effective soil treatment process.
