Ozinga recently partnered with Omni Ecosystems during the 16-month renovation of the Carling Hotel located in Chicago’s Old Town neighborhood. This historic, single-room-occupancy building provides affordable housing for Chicago residents. As part of this revitalization project, two interior courtyards required soil remediation, which was solved efficiently and effectively by the Omni Terrain™, a proprietary remediation solution.
The contaminated soil within each courtyard was capped with four inches of Ozinga Soil Barrier Slurry (OSBS), a highly flowable concrete that eliminates or minimizes the removal of contaminated soils and acts as an engineered barrier to keep the pollutants in the soil. The OSBS was then followed by six inches of Omni Infinity Media™.
We spoke with Omni Ecosystems in more detail about the project.
What challenges were associated with the project?
The enclosed, interior location of the courtyards limited access and necessitated a remediation option that offered ease of installation while keeping costs affordable. For these reasons, Omni Terrain made an ideal solution by meeting this project’s unique accessibility requirements and budgetary goals.
How did Ozinga Soil Barrier Slurry play a role in solving the challenges?
Using Ozinga Soil Barrier Slurry for Omni Terrain’s engineered barrier was an essential part of this project’s success. The highly durable concrete slurry meets the Illinois Environmental Protection Agency’s requirements regarding a contaminated site and provided a rough finish that mimics a natural bedrock surface. On the Carling project, the rapid and flexible installation of the OSBS—it was pumped into the central courtyards—was ideal for the insulated courtyard and made installation easy.
After the installation of the Omni products and OSBS, the courtyards were seeded as lawns and presently provide calming green spaces for residents.
