Thread: a green alternative to build in BALI rammedearth

I applaud your efforts and hope they are successful - as a one-time Californian I'm familiar with the concept of rammed earth building and they have been widely attempted in California but, to my limited knowledge, with only limited success due to the extremes of environment there - heat in summer, wet in winter combined with regular trembles from the ground. Similar to Bali, actually

I hope they stand the test of time.

Only one other hair in my soup, the rammed earth construction I know is usually using clay/terracotta earth. Yours seems to be a white substance - I pray this isn't processed coral...?

looks very poreus? I mean the walls...hope your skull isn't as poreus as the formula,hahaha..just joking!
seriously it looks nice, but not for me. wishing you luck, friendly greetings gilbert.

Why the secrecy about your mixture?

If you come on an open forum and want to "Big" up your project (and possibly sell it???) then you better be prepared to answer some questions about it.

Since I doubt if the world is panting for your secret recipe (you aint Colonel Sanders or Coca Cola) you might just as well tell the people here, who might be able to advance your project, some more about it?

Or is there something to hide?

Oh and some periods and commas are good - I almost suffocated.

From Wikipedia:

"Building a rammed earth wall involves a process of compressing a damp mixture of earth that has suitable proportions of sand, gravel and clay (sometimes with an added stabilizer) into an externally supported frame, creating a solid wall of earth. Historically, stabilizers such as lime or animal blood were used to stabilize the material, whilst modern rammed earth construction uses lime, cement or asphalt emulsions. Some modern builders also add coloured oxides or other items such as bottles or pieces of timber to add variety to the structure."

I'm not an expert, but this contradicts your assertion that clay is a "no-no".

"Ability to keep out the elements. This generally requires the walls to be totally waterproof under all weather conditions. Traditionally clay in the earth used for construction was the key element in keeping out the water. Practitioners should be aware that deleting some or all of the clay under some earth building techniques lessens the waterproofness of the building and that substituting surface coatings and chemicals may not be in the best long term interests of the building. Indeed, the line is often crossed when earth building techniques are used with mixes which are so highly contrived as to be not true earth building but more conventional masonry mixes applied with earth building techniques"

I agree with Markit, have your poured all your punctuation marks into your rammed earth walls? Maybe that's the secret? I think we should be told. :)

There is no way I would contract a builder if he refused to tell me the details of the building materials he was using.

oldest trick in the book....being secretive (formula), creating a hype around the product (using facebook amongst others) ofcourse with the intend to sell.
Nothing wrong with that, if the product is good....but cyclone-proof roof ?? or earthquake-proof walls for that matter?? yeah right...lol.
