Love this idea. But was that phenolic insulation used in the walls.. what about offgassing? You say it’s permeable. But phenolics are not moisture permeable are they? couldn’t you use straw or hemp shiv. Or perhaps chopped miscanthus and lime ? For the insulation?
HI, Russ here from central Georgia, USA. Since in the south east USA we often experience months at a time when the temperature can be extremely hot with high humidity in the day time, I think rammed earth would not work because at night it may only cool off 10 degrees f. That means the walls will not get a chance to cool off, and the interior of the house would swelter day and night in the heat. Perhaps an outer layer of insulation and white reflective paint could be used so the rammed earth will not get as hot in the day, I wonder if that would work? Secondly, I find few materials here to make a keyhole garden with out spending a lot of money for construction materials , but I suspect a rammed earth version of this could work with reusable forms. A cement cap would be needed to keep the rain from washing away the dirt with the intensive rainfall we often get in the summer. The second challenge would be the plants inside the keyhole garden may erode the earthen walls, so some sort of protection would be needed to avoid that. If those problems could be solved, and reusable forms can be made, I think rammed earth keyhole gardens and retainer walls could be a good, inexpensive way to make some very attractive landscaping elements. Any comments?
Hiya there My home burnt down and I thought I'd be rebuilding with rammed earth. I'm technically ''off grid'' so... I was wondering what type of tamper/compressor/generator would be required. So far... it looks like a tamper would require 38 cfm at 90 psi, which is a 6-8k compressor, which requires a 35kw-45kw generator, which would be a good 25k. So that would be around 35-40k just to get started with the basic pneumatic tools? Any way to do it cheaper?
I noticed the global view of areas that use rammed earth has Florida in the USA listed... but I cannot find any examples of this. We live in FL and on a tight budget but REALLY want a basic earth friendly home. Obviously we have hurricane, rainy and humid weather. Is this really an option for us? Earthbag and hemp homes almost seem impossible due to extreme labor and/or difficult to purchase building materials. Please help.
I have 2 questions and a request about rammed house building. 1) How does construction of rammed earth homes integrate electric wiring and water/sewer plumbing especially for a 2 plus more floors? 2) Since the walls are made of earth, how do the walls survive in the shower or if rained on? 3) Is it possible to make/share a video that shows how the electric wiring and water/sewer plumbing lines are constructed and integrated into the walls? Answers to the above questions will be very helpful in deciding about rammed earth homes and help shed a light on how electricity and water will be incorporated in rammed earth building. Thank you so much for the informative information.
I want to know the same thing.. I have seen tons of rammed house construction but none of them show how to do the electric wiring and the bathroom pipes.. Please anyone who can reply 🙏
I see many rammed earth buildings that are only a single floor. If there is a second floor it appears to be wood frame construction. It appears that builders are nervous about multistory rammed earth construction. David Easton is building using rammed earth infills inside a reinforced concrete frame. Are there studies available about steel reinforced, earthquake resistant, multistory rammed earth buildings? My second question is how your wall with an insulation core compares in thermal performance to a sold rammed earth wall of the same thickness?
Great questions I have seen results on studies on many samples by several different university's and institutions but the only multi level public building I have seen is the springs preserve museum in las Vegas NV
@@thomasswedlund1097 I agree. I have heard of mud buildings up to five stories in the middle east. The problem is that they appear to have little or no resistance to earthquake damage. is there data about affordable tall earth buildings that are also quake proof?
@@johnamiddle Thank you. It appears that they have developed a method to securely bond rammed earth with 9% cement to rebar. I must spend more time trying to understand the details of their process. 100 feet is impressive. As they are located in Islamabad they surely have earthquake resistance uppermost in their designs.
Bro Check m s FB nkta q rn to dun. Try to check earthbag. Mas ok un. Problma is ung engineer or building permit. Dq sure if pwd kht s bhy m. Pro ok ang mga gntong bahay. Search m.
water proof cement called portland cement // she also said most subsoils most???? why do the world govs want control of subsoils/??/ some~! have many uses.... $$$$$$
Yes but it needs a almost perfect ratio of sand and clay. Need m lrn reinforced ng rebar at 10% cement or kht apog un ung naresearch q. Try to look also ung earthbag.
Too much to talk about here, but be very careful if contracting out the work in Ontario. This is something you could do yourself, or there are other options than Aerecura. Rammed Earth is in my opinion a viable building material in many ways, but the workmanship is where attention to detail is prudent. There are lots of good reasons to go this route but you don't want to get mistreated and swindled by any of the active builders as I did. If you want to know more, let me know. I'm basically a guinea pig right now with my newly built rammed earth house and so I can give you an ongoing resource of information if you like.
I'm all for sustainability but this feels like a tree-hugging hippy's illusion. Until and unless they can prove that rammed earth can be made commercially and structurally viable at scale by being cost-competitive in multi-story buildings then I won't be convinced that it is a mass solution. Right now it is what it is - a one-off solution in special cases for tree huggers
