Compressed Earth Block Construction


Anyone do any?

Went to a seminar put on by the HBA Im president of today discussing it. Looked like a lot of BS to me for proper construction. The archy who was putting on the presentation stared holes in me when I asked structural questions. How do engineers feel about it? Are the builders doing it able to get a third party warranty? How do you manage a stable sheer transfer between first and second floors? How much does a block machine cost? Does the National Code Council recognize the 1571 psi he suggested it gets?

I wasnt interested until builder said in passing they get 3-400 a foot for CEB customs in New Mexico Now Im interested

Anyone deal with it? Whats its capabilities in real world analysis? Any engineers deal with it?

Im looking at two built in San Antonio next week, by private appointment, allocated by using my presidents seat.

Might be worth looking at if the demand is there.

Not personally involved.

But I have seen a couple built in California.

If they get through Planning/Permit here must be able to do it elsewhere.

They were impressive looking homes....

Heard them referred to as "Rammed Earth Construction".

John, try this....

From my limited knowledge rammed earth is a bit different, but very similar. Although I dont know the difference. Might just be nomenclature.

Suprised it passes with yalls eath quake problem. From my understanding ( reading tonight) it is susceptible to collapse in earth quakes. The mexicans apparently use chicken wire fastened with coke bottle caps to keep it tied together before plastering in eastern mexico.

A popular use of for the mortar, which is derived of the same homogenous mixture as the blocks, is to add crushed glass apparently. Pretty cool.

Although from what I am reading, many builders say they can complete it for as little 15% more than traditional construction.

Ok, looking at your site, Griz, if there is any difference between rammed or compressed I dont see it..

Yeah, hear there are lawsuits under the guise of allergys pending right now in the mid west, but havent checked on it.

All this stuff is like a vendetta against nail benders

Re: Compressed Earth Block Construction


Well if someone comes to you and said....

"Hey John, because of your upstanding & outstanding abilities we want you to build us this 6000' sq ft home"....more

"Lots of exotic wood & this absolutely gorgeous $120/yd wool carpet are included"...

Job is done. Clients are ecstatic, give you a bonus & the guy slips you a box of Cubans....

Shortly thereafter the wife gets an ambulance ride to the ER....

Can't breathe, spasms, wild coughing....

She's allergic to the wool carpet.....

You liable?....

Re: Compressed Earth Block Construction


There are definitely limitations to non traditional forms of building. A friend of mine did a course on "alternative" building. His mother wanted an addition built so he talked her into going with strawbales. Got drawings done and went to get permits. They said no. There wasn't enough precedent for that type of building in the municipality. But wait what about the one built in the suburbs. Wasn't built in the same municipality at the time ( have since been amalgamated but weren't at the time) Unless he had done 6 of those types of builds he couldn't do it. What if he got a consultant who had done a dozen or so? Nope had to be on site everyday. They put up so many roadblocks that it was obvious that they just didn't want it to happen. Maybe other municipalities are different but I would look into permits etc..

Never built with it, but I did see this company's machine 15 years ago, or so - don't remember the pricing:

The liability issue is only the tip of the iceberg,guilty or not,you will have to dig into your blue jeans to hire a liar to plead your case.
