Controlled Modulus Column

Conventional Piling | CMC | Advantage |
---|---|---|
Require concrete pile cap | Could be granular mattress (w/geogrid) |
Cost saving by eliminating “pile cap concrete, piling work” Mostly effective for large diameter tank farm |
Pile : Reinforced Concrete | Pile : Plain Cement Pile | |
Deeper depth to get bearing capacity | Terminate at shallower depth, subject to settlement evaluation |
