Embedded Files
A bored pile is a type of deep foundation technique where a hole is drilled into the ground and filed with concrete and reinforcement to support heavy structures. Micro piles are smaller diameter drilled piles. They offer a viable alternative to conventional piling techniques, particularly in the following conditions.
Restricted Access
Low headroom
Challenging subsurface conditions
Environments sensitive to noise or vibration
TECHNOLOGY AND APPLICATIONS
NEW LOADS IN CONGESTED AREA
Compact drill rigs make construction in limited headroom or access areas possible, permitting facility upgrades or repairs with minimal disruption to the facility.
UNDERPINNING / ARRESTING STRUCTURAL SETTLEMENT
Micro piles can remediate settling foundations or increase the capacity of existing foundations. They can also underpin foundations adjacent to planned excavations to prevent settlement.
CHALLENGING GROUND CONDITIONS
A variety of drilling techniques are available to handle challenging ground conditions such as boulders, karst, and mine geology.
SEISMIC RETROFIT
Existing structures can be retrofitted to meet seismic design requirements. Micro piles can transfer loads through liquefiable soils to competent bearing strata.
SENSITIVE AREAS
Sensitive areas such as hospitals, aquariums, and schools benefit from the low noise and low vibration levels associated with micro pile installation.
SLOPE STABILIZATION
The micro pile slide stabilization system can be used to enhance stability of slopes.
