Abstract
Methods, and apparatuses used in those methods, of countersinking injection tubing below the surface of a structure, such as pavement, so that injection tubing will not extend above the surface of the structure even after movement of the soil, for example, due to frost heave or shrink-swell. Some embodiments employ an injection tube extension and/or an injection tube advancer to countersink the injection tubing within the soil beneath a structure.
