Herbert Hoover Dike Rehab, Reach 1 Cutoff Wall

Lake Okeechoobee, Florida

Lake Okeechobee is the second largest freshwater lake that lies entirely within the United States.  The 143-mile earth dike system that encircles Lake Okeechobee has numerous water controls that provide flood reduction, navigation, recreation, and fresh water for the communities of South Florida and other local and federal agencies.  The Herbert Hoover Dike Rehabilitation, Reach 1 Seepage Cutoff Wall project consists of the construction of a soil-cement bentonite cutoff wall to control seepage through and under the embankment. Reach 1 started at Belle Glade and ended at Port Mayaca.

CES is performing Q/A materials testing services for all four phases of the this Army Corps project and is performing the following tasks per ASTM, AASHTO, and Florida Department of Transporation (FDOT) Standards:

  • Collect & Transport Soil-Cement Cylinders and Cores Samples from the site & from the Contractor’s on-site Laboratory to the CES Laboratory for testing;
  • Perform 28 days of unconfined compressive strength testing per ASTM D-2166
  • Perform Permeability Tests on soil-cement bentonite samples per ASTM D-5084 to check the cutoff wall’s in-place permeability
