Abstract
In order to provide an anchor site in a matrix of solid material which has an accessible face, a socket is formed in the material through the accessible face. A shaft such as an anchor bolt is inserted in the socket, leaving an accessible emergent outer end portion. Via the outer end, explosive force is introduced to or generated in a central cavity of the shaft, which explosive force dislodges and deploys radially essentially outwardly at least one key at at least one level within the socket. Various ways for producing the explosive force are described.
