Micropiles are small-diameter, typically 12 inches or less, deep-foundation piles. An innovative micropiles construction company, Schnabel has specialized drills that can even travel through a standard doorway and drill under an 8-foot ceiling.
Often used to underpin existing structures, micropiles can be installed inside the structure, and their installation produces less vibration than other deep foundation systems. Micropiles are also used to construct deep foundations where there are natural or man-made obstructions, since the drill systems developed for these smaller diameter holes are better able to penetrate cobbles, boulders and other obstructions compared to conventionally drilled or driven-pile systems. Allowable loads for micropiles are typically between 20 and 200 kips, but Schnabel has installed and tested micropiles to 1,200 kips.
Micropiles construction involves the use of small-diameter piles to transfer loads to more competent underlying ground.
In the most difficult drilling conditions, such as landslide debris, Schnabel has drilled micropiles and used them as soldier beams in permanent tieback wall construction. In difficult subsurface conditions and restricted access, micropiles can be a more cost-effective solution for new-structure construction.
With decades of experience performing micropiles installation, Schnabel is able to provide the most cost effective micropile solution for your project.
Sub-surface to street level, safely and efficiently.
NCDOT contracted Schnabel to design and build a repair that would keep this important interstate open and reestablish the eastbound lane. This successful project was completed during the coldest months of the year and within the timeframe established by the State of North Carolina.
