Our location in Greater Washington located in Upper Marlboro, Maryland, recycles non-hazardous petroleum contaminated soils, RCRA non-hazardous soil, along with aggregate based construction and demolition debris. Rubble and stone are crushed and screened to produce aggregate for sale or for use on-site. The majority of this aggregate is mixed with screened soil that has been treated with either calcium hydroxide, portland cement, or kiln dust or any combination thereof, to produce a stabilized material suitable for pavement sub base and sized compactable structural fill material for construction applications.
