The map of the Earth is literally dotted with various reservoirs. And human housing or man -made objects of a different kind often come to them very close, which gives rise to a whole set of specific problems. Among them, in particular, the need to strengthen the coast. It is interesting that in the presence of a whole list of specialized companies involved in solving this problem at a fairly high, professional level, some people prefer to solve it manually. Using for this improvised means, such as interior doors, construction garbage, somehow blinded concrete slabs and so on. Sometimes such measures also give good results (especially against the background of limited financial capabilities), but in 90% of cases they are temporary.
