Damp Box
Yes, they are used together; their jobs differ. DampStop injection and HydroFix damp-proofing plaster work in the wall elements (brick, Ytong/aerated concrete, concrete block). The Damp Box (Nem Kutusu) covers what those two cannot reach: it carries water reaching the foundations and rising in the columns back into the ground. Together (the triple system), the three resolve rising damp in the walls, the foundations and the columns. The correct order on the wall: first the old plaster is stripped, then HydroFix is applied, and once the plaster has dried (24–48 hours) the DampStop injection is carried out.
