Rural water tanks with HFB technique: technical guide

Abstract

This technical guide describes a very simple technique for water tank construction called H-F-B (heart filled blocks). The technique makes use of a simple mould (which can be made even in rural areas) for the manufacture of concrete building blocks. The block production is easy and requires the use of neither energy nor skilled workmen. The laying of the blocks to construct the tank is non-conventional. The blocks are simply placed one on top of the other without the aid of mortar, and then, at intervals, slurry of soil-cement is poured into the top, filling the hollows and producing a monolithic structure.
