Once injected into the mortar bed, DPC Cream slowly releases silane/siloxane into the capillaries of the mortar bed until the cream is completely absorbed. The cream also penetrates the bricks or other masonry substrates above and below the mortar bed. The silane/siloxane reacts with the mortar bed and the bricks forming a permanent polysiloxane damp-course within the treated wall to prevent rising damp.
