Building Foundation Services - Auger Cast Piling

"Having lived and worked in Central Florida over the past decade, I have been fortunate to work with John Puder and his company on multiple large high-profile projects involving Auger Cast Pilings. John and his team are more than reliable contractors; they are excellent people of character, honesty and integrity. I welcome the opportunity to work with them again in the future".

"The facility is designed to seismic loads due to shuttle launch vibration with 350 60-foot piles of support. None could deviate more than two inches from the original layout although current ACI standards allow for three inches. The foundation is independent of the existing sub straight with no bearing load on the soil. Consequently, hurricane damage would be minimized".

Auger Cast Pilings

Auger Cast Pilings Augered Cast-In-Place Pilings are a deep foundation application. A geotechnical engineer would recommend deep foundations when

designing very large loads
soil reports show poor soil quality at shallow depth
site constraints make other applications impossible

Some common applications are for support and anchoring of tanks, high rise buildings, towers and pools.

The process of installing Augered Cast Pilings consists of placing a rotating continuous flight hollow-stem auger into the ground to a predetermined pile depth. High-strength cement grout is injected under pressure through the hollow stem as the auger is withdrawn to fill the augered void, preventing hole collapse, and causing penetration of the grout. Steel reinforcement cages are often placed within the pile for added strength.

There are several advantages in using Auger Cast Pilings over other types of deep foundation applications.

No Casing Requirement – The Auger maintains the integrity of the pile shaft.
High Skin Friction – Rough Exterior provides higher gripping power to surrounding soil allowing greater bearing value.
Less Noise – The Drilling & Pumping process is relatively noiseless when compared to the hammer impact noise created by driving piles.
No Vibration – Minimal disturbance allows for installation in close proximity to other existing structures. Also effective in environmentally sensitive areas.
Close Proximity – Custom equipment and techniques can allow installation in areas with low headroom clearance and tight property line abutments.

Used in both residential and commercial applications, shaft diameters range from 12” up to 48” and quantities can vary from one (1) to over 1,000 depending on design load requirements. John N. Puder, Inc. maintains the necessary equipment and manpower to successfully perform augered cast-in-place piling installations in a wide variety of pile sizes and quantities.
