I am trying to come up with some ideas for a foundation for a small house/cottage. I want it elevated, ideally 16 ft. It is on an island in salt water.
I started by making a standard cone penetrometer, and threading it onto a 1/2 in water pipe. I coupled 2 pipes together and the pipes quickly split at the coupling. I then got 3/4 in water pipe and omitted the cone. I pounded that down to 60ft. I used a 15kg dumbell weight that slipped over the pipe and a clamp that grabbed the pipe that I could drop the weight on. Representative numbers at 60 ft would be 33 lb weight dropped 16 inches 20 times to penetrate 6 inches. Two 200lb+ guys could stand on the dumbell weight and it wouldn't move. I 200lbs+ could jump on it without moving. The location is difficult to access, the ground is saturated, kind of sandy agglomeration. I had been hoping to find hard refusal. I'm kind of used to the Canadian shield where you scrape 4 in and you have bedrock. I'm an electrical/mechanical engineer so this is not my area. I will discuss this with some civil friends. The building regulations are "loose" in this location. I do want a propper solution that will last. Everything needs to be barged in. Any suggestions?
