Contaminated soils are spoils that have originated from brownfield sites, dredging activities or have become contaminated as a result of industrial processes. Urban development and regeneration progress can be stalled by the presence of unforeseen ground contaminants.
Depending on their origins, spoils can appear predominantly dry if excavated from a brownfield site, or predominantly wet if dredged from a body of water. In addition, the presence of physical contaminants such as litter, and chemical contaminants such as hydrocarbons and heavy metals may vary depending on their origins.
The need for soil remediation has increased significantly with rising property values and landfill taxes.
Remediation technologies are generally categorized into ex-situ and in-situ methods. Ex-situ methods involve the excavation of affected soils and subsequent treatment at the surface and extraction of contaminated groundwater. In-situ methods offer to treat the contamination without removing the soils or groundwater.
The technique CDEnviro use to remediate soils contaminated by petroleum hydrocarbons, solvents and pesticides is ex-situ remediation. This technique is faster, easier to control, and used to treat a wider range of contaminants and soil types than in-situ techniques.
The treated material is suitable for use in property expansion and redeveloped land. Cleaned soil can be used as a sustainable source of backfill for contractors.
We will work closely to ensure that a project has complete security and is fully confidential at all times.
Unlike other solutions, CDEnviro's solutions can process a combination of big rock and other materials that come from contaminated soils, see our full range below.
