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
JULY
1997
7-3
The Romans also used a stone block as a hammer. It was hoisted, first by humans then
later by horses, by a rope over a pulley. The downward blow was guided by vertical guides
that are similar to pile leads used today. This method continued until the invention of the
steam engine which was then used to pull the rope. Further development resulted in steam,
air, diesel and hydraulic powered impact hammers plus vibratory and sonic hammers.
Modern day requirements for construction have resulted in various adaptations of the
aforementioned pile driving techniques. The remainder of this chapter is intended to
outline specifications, equipment, techniques and safety items that a Bridge Engineer can
expect to encounter.
General Specifications
Following is a partial list of some of the more important pile driving specifications. Before
starting a project, the Engineer should thoroughly review the Standard Specifications for
general requirements and the Special Provisions for information tailored to the needs of the
specific project.
Typical sections of the Standard Specifications to be reviewed are as follows:
• Section 19: Earthwork
• Section 49: Piling
• Section 58: Preservative Treatment of Lumber, Timber and Piling
The following are taken from the 1992 Standard Specifications and should be reviewed as
applicable:
Section 19-6.01: When bridge footings are to be constructed in an embankment, the
embankment shall be constructed to the elevations of the grading plane and the finished
slope extended to the grading plane before driving piles or excavating for the footing.
Rocks, broken concrete or other solid materials larger than 0.33 foot are not allowed in fill
where piles are to be driven.
Section 19-6.025: The embankment shall remain in place for the required settlement period
before driving foundation piles.
Section 49-1.03: The Contractor is responsible for furnishing piling of sufficient length to
develop the specified bearing value, to obtain specified penetration, and to extend into the
