[papercreters] Re: underground papercrete house? How do I waterproof it?

Y all should not be barking at each other. The site is about cooperation. Most papercrete is made with to little Portland and will become weak when wet. Additionally the free lime left over from a Portland reaction will react with water for further destruction. For this you should replace 15% of the Portland with metakaolin Pozzolan. Water should be shed away from the base of all structures. Do all this and make sure that the cements are at least 80 to 100 pounds per cubic yard and you will be fine. Go to www.evesgarden.org for reference ( I am not there anymore). Barry Fuller is a friend for ten years and we have worked together on testing. He will confirm that I can answer your questions. Coupling your building to the ground is a good idea,while burying it is not. If you have at least an 8" papercrete shell above ground, you will gain nothing but problems from burial. Set the home down in the ground, sure, then earth berm for aesthetics. I will answer further questions if you are serious, but no bitching. Sorry, ladies.
