Pressure Meter

A variety of pressuremeters are used for the measurement of in situ stress, strength and stiffness properties in a variety of soil and rock types:

Driven Pressuremeter
For full displacement testing of a wide range of soil types deployed using boring/drilling rigs or CPT platforms

Self Boring Pressuremeter
Inserted with minimal disturbance for tests in soils ranging from soft clays to fine running sands, it can be used to measure pore water pressure during self boring and testing in conjunction with boring/drilling rigs

Weak Rock Self Boring Pressuremeter
A self boring instrument for use in stronger materials

High Pressure Dilatometer
For tests in predrilled holes primarily in rock and overconsolidated clay

Flat Plate Dilatometer
Used in fine to coarse grain soils (clays, silts and sands) to provide stress correlations
