TIMBER PILE POINTS
Hard cutting timber pile
points help make any job
run more smoothly and
dependably.
Timber pile points protect
pile tips from failure. Points
will help drive through rubble
and other tough conditions
without undermining the
strength of the pile. Points
are made in one piece of
1/4" low-alloy cast steel.
Advanced Uplift
Resistance Anchors
Our TP-807 timber
anchors are made from
TUFLOY cast steel
(90 ksi tensile, 60 ksi
yield) and are galvanized.
Quick assembly in the
field with just holes
drilled through the pile.
DFP casts integral teeth
into each uplift anchor
to provide extra “bite”
into the timber pile.
A full set is needed for
30 ton uplift and 1/2 set
for 15 ton uplift.

He has authored five books, edited 11 books and published
more than 175 papers and reports, including over 80
journal articles covering a range of geotechnical subjects. Born
in Egypt, Iskander got his start in that country’s air force,
where he supervised the construction of roads, runways and
reinforced concrete structures.
“I became a civil engineer shortly after being drafted into the
Egyptian armed forces, where I supervised the construction of 73
buildings comprising a beach front recreational resort for the Air
Force, including a house for President Mubarak,” he said. “Then, I
started my master’s degree over there and I was exposed to geotechnical
engineering and research on slope stability. I went to work at
my master’s advisor’s consulting firm, where I started as a structural
engineer. After designing a few tall buildings, I quickly became disenchanted
by the monotony of following the structural code, so he
advised that I should switch to the geotechnical division. I realized
I enjoyed the consulting business and I decided to pursue a PhD so
that I could practice at the highest level.”
As a doctoral student at the University of Texas at Austin,
Iskander was fortunate to work with some of the giants of the foundation
engineering world, including Roy Olson, his doctoral advisor.
His dissertation committee also included Lymon C. Reese, well
known in the field of lateral capacity of piles, and Don Murff, who
played a key leadership role in writing the API pile design standard.
“My doctoral research dealt with the axial capacity of pipe
piles,” he said. “I was the first to demonstrate that when you
drive a pile into sand, it creates a mini earthquake that generates
a bit of pore water pressure that reduces the strength of
the soil and causes the pile to advance faster. That mechanism
is well understood in clay and is credited with pile setup, but I
was the first to show that setup also occurs in sand, albeit at a
much faster rate.”
