Foundation Underpinning Utilizing Pipe Piles – Innovation Meets Application

Soil Engineering Construction, Inc. has engineered & developed cost-effective foundation underpinning specialties for residential, commercial, and industrial applications. Mitigated measures for the distressed foundations typically involve stabilization through the use of pipe pile underpinning.  The pipe piles usually consist of 2-inch Schedule 80 steel pipe driven to refusal into the underlying formational materials.  

Based on the recommendations presented in job specific geotechnical investigations, pipe piles are typically installed with variable spacing (i.e. 6 to 8 feet center to center) and driven to refusal depths based on sampling analysis.  Once the piles are installed and the first half of the pile cap is poured, it is often recommended that the structure be buildings be releveled to the extent possible on the driven piles.  In areas where differential floor tilt is nominal, stabilizing in place is all that is recommended.
