Introduce you to a simple artificial irrigation method, see how big the seam is (2cm can throw cement filling), small seams can be in the straight seam to the wall to chisel two holes (1 3 distance) so that the hole has a fist big, just throw cement into it, hand slap the door frame cement by the earthquake and sink solid, fill the hole with cement sealing, and then clean it with water and rags, less than 20 minutes can be poured a set of doors. Go for it!
