The method involves moving the profile (1) into the underground (U), such that the compression wave velocity (Vp) of the underground is measured at the foot (11) of the profile. The load-carrying capacity or loosening of the underground can be measured based on the determined compression wave velocity of the underground. The sound transmitter (31) and sound receiver (32) are arranged near the foot of profile. An independent claim is included for profile for producing piles in substrate. |
