Description:
An unbiased, comprehensive review of helical pile technology and
applications
Helical piles have risen from being merely an interesting
alternative for special cases to a frequently requested, more
widely accepted deep foundation adopted into the 2009 International
Building Code. The first alternative to manufacturer-produced
manuals, Howard Perko's Helical Piles: A Practical Guide to
Design and Installation answers the industry's need for an
unbiased and universally applicable text dedicated to the design
and installation of helical piles, helical piers, screw piles, and
torque anchors.
Fully compliant with ICC-Evaluation Services, Inc.,
Acceptance Criteria for Helical Foundation Systems and
Devices (AC358), this comprehensive reference guides
construction professionals to manufactured helical pile systems and
technology, providing objective insights into the benefits of
helical pile foundations over driven or cast foundation systems,
and recommending applications where appropriate. After introducing
the reader to the basic features, terminology, history, and modern
applications of helical pile technology, chapters discuss:
Installation and basic geotechnics
Bearing and pullout capacity
Capacity verification through torque
Axial load testing, reliability, and sizing
Expansive soil and lateral load resistance
Corrosion and life expectancy
Foundation, earth retention, and underpinning systems
Foundation economics
Select proprietary systems

Expectations exceeded (and illuminated!)
I am so stoked about this purchase. Our outdoor lighting situation was terrible- motion-activated lights that cut out after ten minutes and zero power outlets outside. This umbrella light exceeded every expectation. Three brightness modes, all bright enough to actually see what you’re doing — no more squinting while socializing, reading, or attempting to do “work” outside. Cordless, easy to install, and long lasting. If you consistently forget to turn them off when you're done, you'll get about a week and a half from the batteries on the lowest setting.
