Auger Cast Piles (CFA Piles)

High capacity, low vibration and highly versatile: Augercast Piles, also known as continuous flight auger piles, provide a highly versatile system for use across a wide range of applications. 

Pacific Foundation specializes in a wide variety of deep foundation solutions. Watch the video to learn more! 

Augercast piles are cast-in-place deep foundation elements constructed using a hollow-stem continuous flight auger. The process involves drilling to the required depth then pumping concrete or grout through the auger as it is withdrawn, creating a continuous pile. Reinforcement cages are then inserted into the fresh concrete to add structural integrity.

Benefits of Augercast Piles

• Minimal Vibration and Noise: Perfect for urban or sensitive environments, CFA piles are installed without impact driving, reducing disturbance to surrounding structures.
  • Versatility in Soil Conditions: Effective in all soil types – sands, clays, silts, gravels and soft rock.
  • Fast Installation: The simultaneous drilling and concreting process speeds up construction time.
  • Cost Effective: No temporary casings or support systems required, reducing material and labor costs

Application: Where are CFA Piles Used? 

CFA piles are suitable for a wide range of structures, industries and applications including:

• Commercial and Residential Buildings: Supporting structures like the Holden of Pearl in Portland.
• Infrastructure Projects: Supporting facilities like the Three Rivers Wastewater Treatment Plant in Longview.
• Water and Sewer Facilities: Stabilizing critical utilities across the Pacific Northwest.

With years of deep foundation experience Pacific Foundation has successfully delivered CFA pile solutions on many projects. Our commitment to quality, safety and innovation ensures every project meets the highest standards.
