What is a penetrometer, and what is it used for?

A penetrometre is an instrument for determining the consistency or hardness of a substance by measuring the depth or rate of penetration of a rod or needle driven into it by a known force. The Perth sand penetrometer is a tool that is unique to the area around Perth metropolitan area where the subsoil is predominantly sand with very little clay. The unique penetrometer for this area was developed to replace time-consuming field density testing. Slab construction requires uniform compaction of the whole site so vibratory equipment is normally brought in to compact the sandy soil sites. A reliable method of testing the compaction was then needed to ensure the sand pad was ready for construction of the building.
