Rapidobe is a form of construction of our own devising. The idea comes from the simplicity of earthbags, but made faster, cheaper and easier. You can use any dirt, even if it has rocks in it, making it a great option for almost any terrain.
This method can be used for walls, for holding back dirt in an underground construction or retaining wall, even for benches and shelves.

Step 1: Foundation

For a foundation, dig a trench and fill with gravel or rubble. Its width needs to be wider by a few inches on either side than your wall will be. The fact that you do not need a concrete foundation is one of the reasons that makes this method so cheap.
<p>Shouldn't the exterior plaster be more water/vapor permeable than the interior to prevent trapping moisture inside (if this method is used for a building)? The concrete stucco is more waterproof than gypsum plaster (not sure if this is still true though when its painted).</p>
it depends on the climate, but the vinyl is by far more effective vapor barrier than either concrete or gypsum. Having said that, we have not had any moisture issues.
What about on the bottom edge should there be extra as that is a weak point<br>
Love this
This is just like how we build HESCO barriers in AFG/IRQ i never thought to bring the idea home, in a civilian manner! NICE!
I was gonna say the same thing. they are extremely similar. I hate those stupid things with a passion. at least the putting them up and filling them part. I think hesco's would take less time to stand than this though, but i like the idea to bring it home
For those building in the southwest U.S. sun, poly-pro bags last only about a month, maybe two before the U.V. meanies get the better of them. Slip a coat of clay on them before they deteriorate. Nice instructable.
Really a brilliant idea - if there's no rain expected, mere clay can hold off the UV.
alternatively, use a billboard tarp, they last a long time in the sun. Just cover your bags with it.
this is not poly bags. This is billboard vinyl, which lasts a lot longer in the sun. We do cover this with a stucco once completed, but billboard vinyl will last 6+months in the sun.
This looks great. Are there building codes for this sort of thing as well, or is this strictly for building in an un-permitted manner?
