Micropiles systems are preferred supports to stabilize buildings, bridges, highways, towers, other man-made structures and are excellent for underpinnings that are constructed using geotechnical techniques and conventional materials. The names micropile or minipile depict their sizes, i.e., 6"-12" mini, 2"-5" micro. Minipile installations are installed by using drilling and grouting technology. Micro and mini installations can also penetrate to hundreds of feet in depth; each of the piles can support hundreds of tons.
A micropile may be reinforced with large-diameter, threaded bar (75K) to attain the correct design load capacity. Support piles (both mini and micro) are often installed rather than "H" piles because of overhead physical constraints. Rembco uses micropiles (minipiles) as an economical alternative to large diameter drilled shaft foundations, especially in difficult ground conditions, karst geology, or restricted access situations. Construction can be in close quarters under restricted headroom by using simultaneous insertion of casing and drill rod, short casing lengths.
Drilled in bedrock and bonded to the rock socket for load transfer to the wall.
