We inherited a water system with an above-ground poly tank that was buried by the stupid former owners. (Buriable tanks have ribbed walls.) Now it's caving in, and we need to do something else.
I'd like to do something besides poly, and I'd like it to be above ground, so we can still get water when we don't have electricity.
Any experience or advice to offer on ferrocement tanks? It looks simple: make an armature from expanded metal, and trowel on the cement. But I'm sure there's other things to consider.
Thanks in advance for any advice offered!
