Herbert Hoover Dike Gap Closure: technologies employed

The Herbert Hoover Dike Gap Closure Project awarded to main contractor TREVIICOS ( 2017- 2018) included the construction of sections to close the gaps between cutoff walls and existing structures at different points around HHD.

To complete the task TREVIICOS employed two types of cutoff wall technologies:

  1.  cutoff wall by jet grouting abutting the existing structures
  2. the self-hardening slurry (SHS), developed for the first time by TREVIICOS during the work previously performed as part of the HHD Reach 1 Cutoff wall
