O-Cell Load Test  

The O-Cell is a hydraulically driven, high capacity, sacrificial loading device installed within the foundation unit. As the load is applied to the O-Cell, it begins working in two directions; upward against upper side shear and downward against base resistance and lower side shear.

Anchor Reaction Load Test (For Static or Tension Load Tests)

A novel apparatus and method are disclosed for testing piles for load bearing capacity. The novel means and method of the present invention include applying a static compressive force on a pile or group of piles to be tested for load bearing capacity, receiving an equal and opposite reaction force on an I-beam, providing at least two reaction anchor assemblies on opposite sides of the pile, and bracing the I-beam by the two reaction anchor assemblies to hold the I-beam stationary in counter-action against the opposite reaction force on the I-beam.

Kentledge Load Test

Static load testing is an in-situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the Static load test and dynamic load testing in that the pressure applied to the pile is slower. Static load testings are performed in order to measure a design’s axial tension or axial compression. It can also be used to measure its deflected shape under lateral load. Kentledge refers to iron weights used as permanent ship ballast, or iron or concrete weights used in load testing. This method involves the construction of a platform upon which massive weights are placed. These weights bear down on the pile putting it under load. Gauges measure resistance, movement of the pile, and other readings to determine the properties of the ground.
