Would rammed earth walls withstand flooding?
top How deep, how long, how much force? If it is only shallow, you might overcome it by laying a couple of courses of fired bricks to keep the earth walls up a little bit. We have one row (300mm high) of concrete blocks. This also gives you a good start for the formwork instead of trying to get it in the righ position on the footings. Perhaps if you rendered the lower section with a waterproof material it might work also. If there was just a bit of water hitting it for a few days every once in a while and it wasn’t flowing really fast I should imagine you would have few problems, especially if some sort of waterproofing was done. I have some rammed-earth bricks that have been sitting out in the weather for 3 years and they are still in pretty good condition.
