What installation torque is in screw piling and why it is the primary method of verifying pile capacity

Installation torque is the rotational force measured at the pile head as a screw pile is advanced through the ground. It is recorded continuously during installation and expressed in kilonewton metres. As the helical plates thread through the soil, the resistance the ground offers to their rotation increases as the soil becomes denser or stronger with depth, and that resistance is what the torque measurement captures. The higher the torque required to turn the pile at a given depth, the greater the resistance the ground is providing, and the greater the load capacity the pile is developing at that depth.

This relationship between installation torque and pile capacity is what makes screw piling uniquely verifiable among foundation methods. Most pile types require separate load testing to confirm that the installed capacity matches the design intent, which adds cost, time, and programme risk to the project. With screw piles, the torque record produced during installation is itself the verification, provided the torque to capacity relationship has been correctly established in the design and the measurement equipment is properly calibrated. Every pile installed by Capital Piling is torque monitored throughout, and the records form part of the completion documentation issued to the structural engineer and client at the end of the project.
