Thanks I really appreciate the information. I believe your right that this will likely not be cost effective. 348 cubic feet is equal to 9.85 cubic meters and that is A LOT of material lol. Especially since I was trying to do this in my backyard of a town home. The building itself is one continuous building that wraps around the block with a closed in courtyard subdivided into backyards for people. I would have to take a bucket at a time from the front yard through the house and into the back yard to be able to do this. IF I were to buy regular sand I would need like 7.5 cubic meters which would cost like 211 Euro and then the only clay I have been able to find is through an online store that retails 25kg bags of powdered clay for 20 euro a piece. That would be a lot of 25kg bags to equal 2.5 cubic meters. If I were in the states i'd wager I could acquire the items in a more cost effective manner but nothing is cost effective in the Netherlands lol. I have been so excited about Cob since I first learned about it and I guess I was a lil too excited. I can only imagine how much sand and clay would be needed to make a house! WOW! Thanks for all your help and for snapping me back into reality!

Hi thanks for your reply.

From doing a soil test with a jar I have sandy loam soil. The clay layer was all but non existence aside for a few trace particles that didnt form a solid layer. I appreciate you calculating the volume for me but wouldn't the quantity vary between wet compressed cob and loose dry materials? I live in Amsterdam Netherlands and this city was pretty much built on water so I imagine that is why the clay levels arent there. Perhaps if we took the soil part out of the equation and assumed I would be using purchased sand and purchased clay what would be a correct ratio for that? I have seen people say 50/50 while others say 3 parts sand to 1 part clay. I can understand being reluctant to give ratios, but Im just asking for opinions. I will be sure to do my due diligence and research fully before I act and I can assure you I'm not going to come back screaming and yelling if I messed something up. Naturally, I can respect your choice if you feel there is not enough information for you to give an answer your comfortable with. Thanks for your time.

Hi everyone,

I am new here and am excited to find all the great information you have available. I would like to construct a fence that goes around my back yard. I want the fence to be a foot thick and 6 ft tall and run for a length of 58 ft in all. I have no idea as to how much of everything I would need. I will be using my own soil but it is very sandy with almost non existent amounts of clay. How much clay, soil, and straw will be necessary to complete this project? Just a guess is all im asking for. Thanks so much I appreciate your time.
