ABSTRACT:
A hole in a road, airfield runway or in the ground is filled or partly filled by partly filling the hole with a plurality of separate bodies of concrete, rock or other solid material, and filling interstices between the separate bodies and wholly or partially filling the remaining space in the hole with a hardenable mixture of cold setting synthetic resin and filler, which hardenable mixture sets and bonds firmly to the surfaces of the separate bodies. Preferably, before the hardenable mixture is introduced, a flexible fluid--impermeable covering is applied over the partly-filled hole and is sealed to the surrounding ground surface to form a fluid-tight enclosure, and air is evacuated from the enclosure.
