Default ferro cement for fortifications

some ideas we were throwing around after building a water tank with ferro cement ..



Ferro-cement is a method of construction ( there are many ways to do it but here is mine) where you make a frame of steel mesh (about 2 inch mesh) … and attach chicken wire to it every few links

then plaster with a very fine plaster mix on the chicken wire — let it set and re-plaster until its quite thick .. maybe 1 inch

this can be used to make strong water tanks, and ponds, and pretty much anything that you would like from concrete.

I use this then as a mold for stronger things …

for instance i use it to build walls .. make one ferro cement wall and then another a few cm’s appart, forming the outside of a hollow wall …

then back fill the wall with whatever … concrete, gravel, whatever you have handy. ( gravel works well – a filled gap of 12cm’s or 5 inches will stop most small arms upto a .50 cal and as i have said before was used during the Anglo-Boer war by the British in block house construction as it self heals when struck .. the gravel is displaced and then falls back to cover the hole )

let it set and it will be VERY strong … the outer wall being ferro cement and the inner being solid… ( or loose gravel )

Gabions 5 dollars for 100 http://sell.lulusoso.com/selling-lea...h-baskets.html
then use for ferro-cement construction ( they can be stacked when empty and ferro-cement plastered on the outside ) or put in Hessian sacking and use like they do in Afghanistan as sandbags ... -- or just fill with rocks) ; )

if you use this method then maybe use an archway for the roof -- its stronger will hold earth above it up easier .. just a thought

and added some more pics to the link explain better -- would have put them here but the uploaded didn't work so well ..
