Ground Improvement

Ground improvement is an essential component of many construction projects that involve major underground work, unsuitable soil conditions, and/or unstable existing structures.

  • Ground Improvement
  • Bencor’s innovative solution to perform the jet grouting using several multi axis (Bi-Jet) machines enabled the construction of the Bay Area Rapid Transit extension to be completed in less time requiring fewer machines as well as being less costly than anticipated.
  • To reduce the inflow of gas and artesian water into the proposed Dearborn CSO shaft excavations, Bencor conducted a comprehensive drilling and grouting program.
  • In support of tunneling operations, Bencor installed slurry wall access and exit shafts, and a comprehensive ground improvement program along the Kaneohe/Kailua Sewer Tunnel alignment.
  • Bencor utilized two triple axis jet grouting machines that were able to do the entire contract 33% faster than the anticipated schedule, resulting in a project that was substantially completed ahead of the deadline.
