38 Augered Piles

 

Project required 57 micropiles ranging in depth from 13'-31'. Micropiles consisted of 6" diameter heavy wall steel pipe embedded 5ft into competent bedrock. A number 8 rebar was placed in the center of the steel pipe and the micropile was pressure grouted with 5000 PSI neat cement grout. A pile load test was conducted with an ultimate load of 150 tons applied to the pile. Total settlement equaled .13". Design capacity of 60 tons was used for the production piles.

Historic Building Renovation with Micropiles

Pressure Grouting was efficiently and economically used to stabilize loose stones in this tunnel and fill voids behind the tunnel walls succesfully preserving this historic location.

The YMCA planned an addition next to their existing building. 50 foot of augercast shoring allowed less disturbance of the YMCA activities and ensured a excellent overall foundation for the addition.

Augured Pile Shoring

 

Augercast piles made for an excellent temporary shoring for a new press pit at a manufacturing facility.

Auger Cast-In-Place Piles

In this application we used augered piles to serve as shoring walls for a new pit and as foundation piles for a new vat. The augered pile method allows the shoring to be installed in one continuous operation followed by excavation to full depth.
