Mini Caissons Steel Pipe Casings with High Strength Bars

Mini caissons are designed for deep foundation projects in densely populated cities and generally run 12 to 20 inches in diameter. Mini caissons are steel pipe casings used in conjunction with high-strength bars to limit the disruption of a high capability load column to nearby buildings and underground structures. Like micro piles, mini caissons can be installed through almost any subsurface and are ideal for projects with minimal work space and low headroom. Mini caissons are capable of handling larger loads than standard micro piles.
