Nellis AFB Hospital Tunnel Sealing - Las Vegas, NV

LEARN MORE ABOUT OUR RECENT CASE STUDY ON HOW EAGLE DENSIFIED BASE SOILS FOR NELLIS AFB HOSPITAL IN LAS VEGAS, NV.

Project Challenges

• Hospital floor slabs began to settle up to 1” on both side of a utility tunnel running below the hospital

• Hospital is fully operational 24/7 and drilling through the interior floor was not an option.

Design Approach

• DCP test was performed in 6 areas throughout the hospital to determine appropriate injection depth

• Horizontal injection points were installed every 4ft through walls of the underground utility tunnel to address slabs on both sides of the tunnel and avoid the disruption of drilling and working inside the hospital.

 

 Project Support

• Project was monitored by the US Army Corps of Engineers

• EagleLIFT worked under United Excel, general contractor, who was performing a multi million dollar renovation to the hospital.

Results

•  Although the scope of work only called for stabilization of base soils to allow for the self-leveling overlay to be installed, many areas of the floor were returned to the level

• Weak base soils were successfully densified.
