How much shrink will you get with compaction
Day hit the nail on the head with knowing the material you are moving. 25% would be a very crude example and would work for sand to sandy lean clay. If you are in a real plastic clay 35% - 40% wouldn't be out of the question. I wouldn't bid a plastic clay site with a 25% shrink factor, lucky for me this area is usually sand - sandy lean clay.

The SAVE Compozer uses a forced driving/lifting device that rotates a casing pipe to penetrate the ground. After the casing pipe reaches a certain depth, repeated lifting and driving in a wave-like pattern as the sand is discharged compacts the sand into a large-diameter, well compacted pile. With no use of vibration energy, compaction does not create loud noise.
