The positive pressure developed at ice-water interfaces in a soil as it freezes  IPAPermafrost 

The positive pressure developed at ice-water interfaces in a soil as it freezes (freezing of in situ pore water - 9% expansion). It is also known to result in a heaving pressure or frost-heave pressure that is responsible for the heaving of utilities, foundations and pavements. Ice-water interfaces occur at the contact between Ice lenses and the Frozen Fringe.  TrombottoGeocryology
