Trunk Sewer

based in Southern California ABI Mobileram Trunk Sewer This project involved installing a deep sheet pile shaft to control groundwater and access an existing sewer line 35 feet below grade. Our crew drove 50-foot sheets using the ABI Mobilram, working just 15 feet from an active powerline—requiring precise equipment handling and enhanced safety measures throughout the operation.

Shaft 4

based in Southern California Giken UP150/HVR100 Shaft 4 This project required installing a sheet pile shaft beneath an existing bridge with just 23 feet of overhead clearance, making access extremely limited. Our crew spliced and installed 35-foot sheet piles using the Giken UP150 and HVR100, specifically selected for their ability to operate in tight, low-clearance conditions. The shaft was needed to block groundwater and provide access to an existing sewer line 20 feet below grade.

NOS Emergency Repair

based in Southern California Giken Silent Piler Auger Crush NOS Emergency Repair This emergency project involved the installation of 65-foot sheet piles to safely access a fragile, existing sewer line located 50 feet below grade. Due to sensitive site conditions and the sewer line’s vulnerability, vibration-free methods were essential. Our team utilized the Giken Silent Piler with Auger Crush to successfully navigate extremely challenging ground conditions, including large cobble. Upon completion of the sheet pile shaft, our crew installed and welded a three-ring waler support system to ensure stability.

P1-105

based in Southern California ABI Press In P1-105 This project involved installing two permanent sheet pile walls around a live sewer line to protect it while providing access for the installation of two new adjacent lines. Because the existing line was active, a vibration-free method was critical. Our team used the ABI Press-In Method to safely install 30-foot sheets with zero vibration, maintaining the integrity of the live line throughout the operation.
