Abstract

A method and a device for delivering a substance into the bulk of an open-pore material (1, 16, 36), and the resulting material, are disclosed. A dispersion of ion species within a solution is caused to migrate electrophoretically through the bulk of said material, from a first to a second discrete area thereof, by means of an applied electrical field (E). The dispersion contains two reactive ion species (4, 5) with opposite signs. Said ion species are normally capable of interacting to give a hard and/or hydrophobic element (12). The one ion species whose sign is opposite to that of the zeta potential of the material is combined with a vector (13) having a zeta potential (14) with the same sign as that of the material. Stones or structures may thus be consolidated.
