That’s the response I always get when I’m describing my favorite building material. Not surprising since it occupies a spot in that backwater known as ‘alternative building materials’. Papercrete is just what it sounds like actually. It’s concrete made with paper. I tell people to think of it as industrial paper mache. It’s inexpensive to make, amazingly sturdy, lightweight and insulating.
I didn't invent it but I have played with it quite a bit over the past several years. In this Instructable I'm going to go over a little of the history behind it, exactly what it is and how to make and use it. By the time we're done you'll love it too!
