Insufficient information, but at a guess: the displacement?
The different substances you use to move your raft
If the soil is so lose that it cant hold the building even with pile foundation. So, piled raft foundation is used which make the building to float like a boat. That obeys Archimedes' principle-it is buoyed up by the weight of the earth displaced in creating the foundation.
No there isn't, and there's not going to be because that last answer said June 31st... there is no June 31st 2009! theres no raft wars 2 and there will never be one
If you were in a raft and you were going east of Florida you could end up in several places. You would be in the Gulf of Mexico and could land on the coast of Mississippi, Louisiana, Texas and even Mexico.
Its all about the type of soil and the building structure is going to build on it. If the site soil is not the type (i.e; like clay soil, the soil cannot having load bearing capacity etc.,) for constructing big buildings, its better to go for raft foundation. Because, this type of foundation spreads the load of building to overall area and if the foundations are constructing very near by each other means. In that time also, this foundation can be laid.
A "Raft foundation" is something you'd use on ground that's not that stable. They actually float like a raft on soft soil.They need to be really strong to bridge the squishy spots without cracking, so they are heavily reinforced, lots and lots of rebar and screen.The underside is usually waffle like, I have no idea why.You'll need to talk to an engineer to to figure out how thick it needs to be, it will depend on the size of the structure and how bad the ground is. The building inspector is never going to let you do this without a stamped set of plans

They raft.
The raft is breaking up, sir! Let's jump onto another raft as soon as we can. That's Tom Sawyer's raft.
