Which buildings are you using? They never break before after the 8th collection. So if you use moon robot and collect at 100% it will take at least 8x15h=120h before you get the first hammer. On the other hand using Mesurys and collecting at 70% (after 2:48h) your buildings should break on average after about 40h (i.e. after the 14th collection on average, see repair page).
