Every building or structure that is built in or on the earth imposes loads on the soil supporting the foundations. The stresses set up in the soil causes deformation of the soil with stress failure being caused by slippage of soil particles, which may lead to sliding of one body of soil relative to the surrounding mass.

All shearbox assemblies are designed to fit the carriage of the Direct/Residual Shear Apparatus. They are supplied complete three porous plates, on retaining plate and a loading pad. The three sizes supplied comply  with the relevant requirements of BS 1377 and ASTM D3080. All assemblies can be used for quick shear tests or drained/residual shear tests. Optional accessories are available including specimen cutters and extrusion tools. The table shows the complete range of shearbox assemblies and accessories.
