Mechanism of Sand Drains
Advantage of Sand Drains
The weight of the piled sand forces the water in the clay to move outward along the sand piles.
Application of One Million Sand Drain at KIA
Reclamation Three distinct
grades of sand, gravel and rock from nearby mountains
Four years and 750 million cubic feet of fill
Transportation on Ground: Conveyor Water: Barges
