We find exact solutions describing Ricci flows of four dimensional ppwaves
nonlinearly deformed by two/three dimensional solitons. Such solutions are
parametrized by five dimensional metrics with generic offdiagonal terms and
connections with nontrivial torsion which can be related, for instance, to
antisymmetric tensor sources in string gravity. There are defined nontrivial
limits to four dimensional configurations and the Einstein gravity.
