We call this style of roof losa down south, it's very common ... losa means 'slab' i guess, both in the sense of a ferrocement slab and a grave marking slab, the masons have lots of jokes that play on the relation between them .... it's an art to make construction losa well, they have a number of tricks, especially in placing and moving the backup form under the steel net, it's not easy to get this right, but very important to do so, especially when the roof you're building will be in the future the floor of the second storey [so it is completely horizontal, yet must hold water] ... the concrete mix must be just so, and the mason skilled in working it ..... the only other roof style is corrugated sheet metal, galvanised steel called lámina ... if you've got the money you do both, make a sealed roof of losa and then lámina above it, this provides insulation against the heat
Piranhas - they only occupy a place in the food chain, they're not the end of it ... everything, absolutely everything, is part of a cycle ... the most vicious predator must still excrete fertiliser, and in the end it will be eaten |
