Lime And Sand Pile
The lime and sand pile modification technique comprises vertical deep holes in the ground filled with dry quicklime, with dimensions of about 0.5 m in diameter and 10 m or greater in depth. Lime piles are constructed in situ by filling the hole created in the ground with quicklime, without mixing it with the natural soil, using a mechanized hollow tube. The improvement mechanism comprises diffusion of divalent from the quicklime into the soil.
Sand compaction piles can be used to improve marginal sites for stability, liquefaction, and settlement applications. Lime mortar is a traditional building material, and is now only normally used for restoration, and repair of old buildings.
