Project Description: Our firm completed this project for the renovation and rehabilitation of two large concrete underground reservoirs for in Washington, DC. Major work items included: selective demolition; concrete repairs; site work and utilities. There was also extensive process mechanical; security and surveillance work.
Another major item of work was the installation of geofoam and membrane liners (pictured). The foam is for lightweight protection on top of the reservoir roof and the membrane liner is for waterproofing.
Working inside the reservoirs was challenging. Stringent safety measures were put in place. The project was phased due to water usage restrictions by DC Water.
