Drawings to Specification. [Class 41] [Also in Groups X and XXI] Soils consisting of or containing clay are hardened by passage of direct current between two aluminium electrodes inserted therein. To increase the carrying capacity of wooden piles they are covered with aluminium sheet, which may be only a fraction of a millimetre in thickness, and current passed between them ; a hardened crust is thus formed around the piles.
