Micropiles / Minipiles
Micropiles and minipiles are
excellent underpinning, which are constructed using
geotechnical techniques and
conventional materials. Piles
(micro
or mini) are preferred
supports to stabilize buildings, bridges, highways,
towers, other man-made structures, etc. The names minipiles
or micropiles depict their size, i.e., 6"-12"
mini, 2"-5" micro. Mini piles installations are
installed by using drilling and grouting technology. Micro and mini
installations can
penetrate to hundreds of feet in depth; each
of the piles can support many tons.
Micropiles may be reinforced with large-diameter, threaded bar (75K) to attain
the required design loads.
Micropiles are also often installed rather than "H" piles because of
overhead physical constraints.
Micropiles construction can also be in close quarters under restricted headroom
by using simultaneous insertion of casing and drill rod,
short lengths.
