Abstract

A core sample is removed from a soil or rock mass by boring a hole in the mass to a depth at which sampling is to begin and thereafter cutting a second hole in extension of the first hole and of a smaller diameter. The second hole is of a length equal to the desired sample and the second hole is filled with a hardenable binder such as cement whereupon a rigid reinforcing member is introduced into the still fluid binder for the depth of the second hole. After the binder has hardened a core of a diameter equal to the first hole is cut from the mass, the core being inclusive of the binder and reinforcing member with an intact surrounding sample of the mass.
