Containment Caps & Liners

While excavation and treatment are common solutions for many soil and groundwater remediation projects, containment can sometimes be a more appropriate and more economical alternative.Our crews are experienced in utilizing the specialized equipment necessary to construct containment systems in precarious and difficult-to- access locations. CEI has performed containment activities in and adjacent to water bodies, under structure footings and foundations, and within environmentally sensitive areas.On one site we installed a vertical barrier, similar to the sound wall system normally used on highway construction projects,to serve as a vertical cut-off wall.This, along with a soil cap, kept landfill debris from eroding into an adjacent river. We have capped and contained sites contaminated with both organic and inorganic compounds including chromium,lead, arsenic, PCBs, TCE, coal tar, and BTEX. In each case,CEI delivered the safe, sound, and cost-effective solutions our clients required.
