Our
techniques apply when adding new structures:
especially
rock anchor,
microfine cement,
soil nailing,
micropile
installations for
foundation support.
We
specialize in
slope stabilization,
anchors,
permeation grouting,
foundation repair
and support,
grouting,
soil nails,
rock drilling,
micropile installations, and
sinkholes. We
use a
problem-solving approach geotechnical
architecture of buildings, bridges,
water plants, sewage plants, tunnels,
sinkholes,
caisson,
shoring,
underpinning,
agriculture, and
roads
construction. We
are experienced in these applications:
micro piles,
sinkhole repair,
permeation grouting, pressure
grout,
soil nails,
chemical grouting,
micropiles,
compaction grout, and
rock anchors.
Our specialties are
rock anchor,
acrylamide and
compaction grouting,
mini piles,
sinkhole repair,
micropiles,
acrylamide grouting, and
soil nailing.
We will continue to dedicate ourselves to
excellence,
including
insurance mortgage, in our performance, in our
integrity, and in our relationships with our
customers. We will carefully weigh our
decisions, actions, and results to make sure
that we remain the most trusted name in the
geotechnical contracting industry. Please

Driven Piles
7-4
cap or footing block as indicated on the plans or specified in the Special Provisions.
(Estimated tip elevations shown on the plans are used only for estimating the quantity of
piling needed for the structure.)
Section 49-1.05: Pile hammers shall be approved steam, air, or diesel hammers that develop
sufficient energy to drive piles at a penetration rate of not less than
1
/
8
-inch per blow at the
design bearing value. Steam or air hammers shall be furnished with boiler or air capacity
at least equal to that specified by the manufacturer of the hammer to be used. The boiler or
compressor shall be equipped with an accurate pressure gauge at all times. The valve
mechanism and other parts of steam, air, or diesel hammers shall be maintained in first
class condition so that the length of stroke and number of blows per minute for which the
hammer is designed will be obtained. Inefficient steam, air, or diesel hammers shall not be
used.
Section 49-1.06: Piles, to be driven through embankments constructed by the Contractor,
shall be driven in holes drilled or spudded through the embankment when the depth of new
embankment is in excess of 5 feet. The hole shall have a diameter of not less than the
greatest dimension of the pile cross section plus 6 inches. After driving the pile, the space
around the pile shall be filled to ground surface with dry sand or pea gravel. (This is to
prevent frictional down drag on the piles due to differential settlement between the new
embankment and original ground).
Section 49-1.08: Except for piles to be load tested, driven piles shall be driven to a bearing
value of not less than the design loading shown on the plans or specified in the Special
Provisions.
Section 49-1.08: When a pile tip elevation is specified, driven piles shall penetrate at least to
the specified tip elevations.
Both of the preceding specifications are to indicate that there are in fact two different pile
driving requirements: (1) A specific pile tip penetration, and (2) a prescribed bearing value.
Pile Driving Definitions
The following is a partial list of some of the definitions unique to the pile driving trade.
These are the most common terms used and should be of benefit to those new to pile
driving work. Refer to Figures 7-2 through 7-8 for the location of the defined terms.
