3 of 3 Timelapse - Constructing the concrete fire shelter/bunker DIY

[iroqueez]

Did you built it especially for fires? I just wonder, regarding to the living surface inside, and the volume of air, how long you could stay in it. Did you installed something like an air filter or a water tank?

Only 1 major concern... I dont think I would want to be in there if an earthquake hit. It would be game over,.. fast

I could see this structure as being a safe place to escape a tornado, lightning, hurricane, BUT, I am skeptical about it being a place to escape a fire storm, because you have a forest of trees surrounding your structure. When a forest is on fire it burns all the oxygen out of the air. Just the heat from a fire storm can kill you from a long distance. Then there is the issue of smoke. It is smoke that kills people more than the heat or the flames. How are you going to deal with those?

Dry? After it was mortared with plenty bondcrete, we concreted the large gaps with bondcrete mortar, after that cured we filled smaller gaps with liquid nails. Then all joints were covered with aluminuium sheets liquid nailed to the concrete. Then covered the whole lot with cardboard, then sand sculpted top to be sloped away from joints. Then covered with thick plastic sheets aligned so water flowing down will not go under joints. Then more cardboard, then burried with earth :) Bone dry inside!!

I cant remember costs now, it was one truck of concrete, about 4 or 5 cubic meters. High MPa. The blocks were AU80 each, the box culverts were about 120. The slabs on the back were about 80 each, however we sourced our concrete carefully because if it were retail price i belive wed be paying about 2000 per culvert and those blocks dont get sold publicly. You need to know someone who works in that industry and they can get anything like this (dirty/chipped) dirt cheap.

What did this cost you? How will you keep it dry?

Its not finished.... building our house takes a lot of time... so this project was put on hold until the near future. In future it will be air tight and completely burried with exception of the tunnel entrance. I will document the rest when the time comes and put it on youtube...

How do you expect to survive in this thing if this is the completion video?

[theNowickis]

its still like this.... half buried waiting for some time to build the entrance. This will be an L shaped entrance and the entire structure will be burried with exception to doorway.
