ABSTRACT:
A method of securing an anchor rod in a borehole at an underwater location without the use of expanding force includes a first step of partially filling the borehole with a flowable hardenable bonding mass. Next, a cartridge containing a hardenable bonding mass is placed in the borehole and a part of the flowable bonding mass is displaced from the borehole. Since the cartridge substantially fills the borehole, the flowable bonding mass flows between the borehole surface and the cartridge. Finally, an anchor rod is driven into the borehole breaking up or destroying the cartridge, so that the two bonding masses mix, harden and bond the anchor within the borehole.
