Here
we shall attempt to answer any questions you may have about us or
our systems. If you have a question not answered here then please

Q.
How do you join piles?
A.
Various methods
of spilcing piles are used depending on the type of pile.
1.
Precast concrete piles are spliced using:
1.1
G-Pile non impact joints are an engineered designed joint consisting
of two parts, one of each that are cast into the pile segments and
joined with steel pins. These can be designed for both compression
and tension piles.
1.2
A galvanised steel pin inserted into holes cored in the end of the
pile segments. These are used only with compression piles.
2.
Steel Piles
The
steel piles are either joined by screwing the segments together
by means of male/female threads that are incorporated into the pile
segments or, if threads are not available, by welding the segments
together.
3.
Timber Piles
Spliced
by either drilling into the end of each segment and epoxying a steel
bar into place or by using a proprietary steel tube joiner that
fits over either end of the segments being joined. A hole is drilled
through each segment and a steel pin inserted.
Q.
What
precaution is required for the construction site to operate our rigs?
A.
We require a flat site compacted to a level that a
concrete truck can traverse.
Q.
How
many men are required to operate your large 6,000 kN 'G' pile rig?
A.
5
men including crane driver are required.
Q.
How
are our piles certified?
A.
All
our piles are independently certified by consulting engineers, URS Australia.
Q.
Can
you design the pile caps to suit a particular piling system?
A.
Yes,
our engineers can design and certify the cap and piling system.
Q.
Is
there a tendency for your piles to wander off vertical as they are
being driven?
A.
No.
The gripping system holds the pile vertical. Test holes drilled alongside
our 'pushed' pre-formed concrete piles indicate this is not an issue.
Q.
Can
you drive a raked pile with the 'G' Pile system?
A.
A slight
rake is possible but not preferable. We would provide an alternative
system of vertical piles.
Q.
Obviously
our 'G' Pile system is not appropriate in all geo-technical conditions.
Where does it best apply?
A.
We
have applied the method in a number of geological conditions ranging
from soft and stiff clays, loose and dense sands and gravels, to weathered
rock in N.S.W., Victoria, Queensland, South Australia and Western
Australia.
Q.
How
do we provide for a spliced pile in tension?
A.
APC
has specially designed components to achieve a successful splice in
these expected circumstances. Refer to question 1.
Q.
Would
we expect any difference in settlement of the pile when driven by
your 'G' Pile system over the conventionally hammered pile?
A.
No.
Tests by independent engineers have confirmed the reliability of our
systems. Remember, every pile that we install outfit the 'G' Pile
system is static load tested to its ultimate load
