    Menard Pressuremeter - practical limit?

    I just remembered anotherthing: * What are you looking for? is it a modulus? if that is the case, the range of values we have obtained from various site ranged between 650 and 1500 kg/cm2. The 650 value was obtained in marly formations (U.C ~ 50 to 100 kg/cm2)
