Waterproofing.
Water finds the one place a building was not sealed: the roof slab nobody slopes, the shower floor tiled a day too soon, the tank wall with a cold joint in it. These guides take one of those places at a time. Each explains where the water comes from, which kind of membrane suits that surface, how much of it a square metre takes according to the maker's own data sheet, and how long it needs before tiles or water go on top. They are written for Tanzania's two rainy seasons and its coastal humidity, where a slab dries more slowly than the label assumes.
