The problem of the squeezing out of a solution from aggregates 
in a porous medium has been considered and investigated. A specific 
feature of the problem lies in taking account of the existence of 
two compaction zones in deforming aggregates of a porous medium. Features 
essential to mass transfer in a deformable aggregated porous medium 
have been determined and analyzed.
