Expert drilling services that specializes in micro piles. Piles are typically between 4” – 12” in diameter. Also referred to as “ pin piles” or “mini piles” they can often reach depths in excess of 150ft. Most are vertical, but some are installed battered depending on the application.
Each pile often consists of high -strength steel casing, grout, and rebar. They are used in various ways; often when typical piles are not feasible due to various onsite or subsurface restrictions.
We see them used generally when there are :
- Low clearance and or restricted headroom issues
- An existing foundation needs to be replaced and or strengthened
- Subsurface Soils conditions are challenging for larger diameter piles
- New foundations that are near existing structures / foundations
- Slope stabilization concerns with using larger more typical drills
- Seismic retrofits in difficult restricted access areas
- Settlement concerns that create a need for settlement prevention
With hundreds of Micro piles installed over the years, we are proud to add this to our over growing list of alternate foundation options we at Curtis Drilling offer as a service to our customers. With various machines for different applications; we consider micro piles a cost effective approach when certain onsite and or subsurface conditions present themselves.
All micro piles can be tested in accordance with ASTM testing standards and procedures to ensure all areas of the load capacity as specified by the design team are meet. Upon completion and approval of the pile; all necessary structural loads can as designed then be transferred to the micro pile itself. Please consider micro piles as a proven method when designing your next project.
