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

Not as expected
Size: 6 Inch, Color: Bone
I have been looking for these ever since we got a similar one at Sierras for our 1 1/2 yo Cane Corso. She is brutal on chew toys and the first one from the box store held up well. However, this did not hold up as well and she was done with it in less than a week. Still looking for that perfect toy.

More durable than expected.
Size: 5 Inch, Color: Raccoon
I was walking through my front room the other day when I noticed a suspicious spot on the floor. It looked like something I should not touch without gloves. As I got closer, I realized what it was. It’s the ‘guts’ from this toy. My dogs (Pit Bull and German Shorthaired Pointer) were each given one. Both are aggressive chewers with their toys. They ATE the faces off these toys and now play with the felt interior. I’m still trying to figure out how they ate through leather while the felt remained intact. Regardless, they still play with them. Now they are basically semi-fuzzy throw toys we can throw in the house because they don’t leave marks on the wall if our aim is off. Sometimes things work out the way they should. :)

Great with supervision
Size: 6 Inch, Color: Bone
My dogs LOVE these, but removing a star because these apparently are VERY delicious and they will ingest what they rip off if I don’t supervise; also removing a star for how quick they’re able to tear these up. These are like catnip for dogs, I’ll still buy them!

Don't waste your money!!
Size: 5 Inch, Color: Fox
With in minutes my puppy was pulling on the middle fiber stuff. I was worried he would choke/ingest it so I immediately threw it away just like the money I apparently threw away on this unsafe and misleading chew toy.
