The bearing stratum is logged during installation drilling to guarantee that bearing capacity is satisfactory.
A higher-strength metal casing is typically drilled all the way down to the design depth during the installation procedure. A reinforcing bar is put into the casing, and substantial-strength cement grout is poured into it.
Unstable Soil Problems: These piles excel in locations with weak or unstable soil, delivering reliable help where other Basis methods may are unsuccessful.
Specified soil circumstances will obstruct installation and even thwart the development of common underpinning answers.
Micro piles are utilized in regions anywhere geological formation is large, urban backfills, locations getting floating boulders or distinct difficult terrains that will’t even be accessed with a traditional pile.
