Originally developed by the California Division of Highways in the 1930’s, this test has been developed and adapted to form the basis of most testing for subgrade quality and compaction.

If you have excavated virgin land that you wish to construct on, and have found clay or sand and want to know if it’s strong enough to bear weight, a sample can be taken and used in a CBR test.

A sample of the material that needs testing is loaded into our mould, either on site or in our laboratory. Then a 3sq inch (approx. 50mm dia) plunger is loaded against the sample and the penetration into the sample is measured at various increments.
