Proudly serving Florida since 1989
L.R.E. Ground Services, Inc. was hired by a General Contractor to install auger cast piles at a property in Clearwater Beach, FL. The property owner wanted to build a pool onto the structure, so compression auger cast piles were required to provide support, withstand scour, and endure coastal weather conditions.
Auger cast piles, also known as continuous flight auger piles (CFA), are used for load transfer in deep foundation projects and also for contiguous and secant pile retaining wall construction.
CFA piles are a quieter, faster, very economical alternative to conventional bored piles and driven piles.
Auger cast piles are ideal when piling is needed in soft soil conditions.

A CFA pile is cast-in-place using a hollow stem auger with continuous flights. The pile is drilled into the soil to the final depth in one continuous process, contributing to the speed of installation and minimizing noise and vibration.
As the auger is withdrawn, the soil is brought to the surface and at the same time, concrete or grout is pumped through the hollow center of the auger stem to the base of the auger, providing continuous support of the hole. When necessary, reinforcing bars are then placed into the grout-filled hole immediately after withdrawal of the auger.
A reinforcing cage is inserted into the grout to strengthen the concrete.
CFA piles can be constructed as single piles for a soundwall, however, CFA piles are typically installed as a group, such as for a deep foundation.
With our Casagrande B175XP rig, our experienced drill rig operators are able to easily penetrate rock and perform piling in tight spaces.
We also use a data acquisition system to ensure the best possible CFA cast pile installation every time.
