GeoPAC® : Auto-Controlled Pressuremeter
MENARD PRESSIOMETER TEST ACCORDING TO THE EN ISO 22476-4 STANDARD
What is GeoPAC® ?
Following in the footsteps of Louis Ménard, Apageo proposes an exclusive
device: GeoPAC®, the Auto-Controlled pressuremeter, driven by GeoBOX®.
GeoPAC® , such as its predecessor the Ménard Pressuremeter, allows Ménard
pressuremeter test according to the EN ISO 22476-4 standard.
It is the first equipment totally automatic and autonomous on the market that
manages all the different steps of the test, ordered by the operator.
GeoPAC® makes the whole process easier to conduct for the operator,
reinforces the reliability of the results, and reduces the time of preparation.
What makes GeoPAC® being so original?
The ingenuity of the system lays on the physical separation of the 2
circuits necessary to pressuremeter test: Gas and water (exclusive
system, never seen on the market). Thanks to this technology on the
water circuit, the accuracy on water regulation is nonpareil.
GeoPAC® specifications

• Weight : 45kg (empty)
• Power supply : 9 – 18VDC
• Handle for transport and wheels
• Volumeter capacity : Roughly 1200cm3
Ménard Pressuremeter test
A pressuremeter test is an in situ controlled loading test performed on
the wall of a borehole using a cylindrical probe that expands radially.
From the test readings (volume variation based on controlled
pressure), a stress-strain curve can be obtained for the soil at hand in
the case of plane deformation.
Testing enables definition of three parameters:
- Ménard pressuremeter modulus (EM)
- Creep pressure (Pf)
- Limit pressure (Pl)
