Helical Piles & Anchors
CHANCE® helical piles (compression) and anchors (tension) are an instant foundation system that features
real-time tracking of the torque-to-capacity ratio during installation. This helical foundation system is segmented
with helical bearing plates welded to a central steel shaft. Load is transferred from the structure through the shaft to
the soil through the bearing plates.
High load capacities and lateral stability in weak surface soils
can be achieved by utilizing the Helical Pulldown™ Micro pile system
Centralizers
Foundation Technologies, Inc. has developed a comprehensive family of centralizing
devices for most applications of foundation pile and drilled shaft construction. ShaftSpacer ® system guide and alignment products have built-in quality control keeping
reinforcing steel in its proper position during concrete replacement. From drilled
shafts with sizeable steel cage to auger-cast piles with single bars, the ShaftSpacer®
and Unispacer™ family of centralizers can help keep you on-line and in a positive
position.
Structural Reinforcement
HJ3™ is the strongest and most versatile product in structural reinforcement.
With over 20 years of research, development, and experience, HJ3 Composite Technologies
utilizes the breakthroughs in aerospace and material science to create cost-saving structural
solutions. HJ3's line of composite technology include high-strength carbon fiber and glass
fiber products that are stronger, lighter, and far more cost effective than replacement of existing structures.
FRICTION REDUCTION
"Negative skin friction" or "downdrag" are terms defining forces on piles installed through soil deposits
undergoing consolidation. These forces reduce the usable capacity of the piles installed, and should be
seriously considered when the ultimate capacity of the pile foundation is evaluated. The negative shaft
resistance is the reverse of the usual positive resistance developed along a pile's surface. These
negative forces increase the axial load on the pile and can be significant.
