Plate load testing

Plate load testing or plate bearing testing, is carried out in accordance with BS 1377 Part 9: 1990 Standards, using either an incremental or constant rate of penetration. In this test, a plate of known dimensions is jacked against a reaction load, usually the underside of a suitably weighted tracked excavator which provides the kentlidge, and deformation readings are taken. The results can be used in conjunction with site investigation data then to determine whether the ground has sufficient bearing capacity to support temporary structures such as cranes or piling rigs.

A prediction of settlement can also be made from the results.

Plate load tests can also be used to provide a CBR equivalent value, and are generally considered to be more representative than CBR tests in soils of mixed and variable size or coarse soils (greater than 20mm particle size).

GeoCon can provide in house plate load testing nationwide for our clients.
