Myth's &
Misconceptions about Pressed Pilings:
Myth 1:
Pressed pilings don't stay in alignment.
Fact:
Pressed pilings can be driven into the sub-strata up to 50' without significant
misalignment. Alignment can be check at any point during the pressing process by
dropping 2' sections of rebar down the center hole to insure proper alignment.
Because these pilings are being pressed at such high psi, they will cut through
any root and rocks on the way to solid sub-strata.
Myth 2:
Pressed pilings are not
time-proven for foundation repair.
Fact:
Pressed pilings have
been in wide use for foundation repair for almost 20 years. They also have the
lowest failure rate of ANY repair method in residential use today.
Piling systems are not only
used for home repair but bridges, oil rigs, and numerous other applications
where load-bearing reliability is extremely critical. Pre-cast concrete
cylinders are the most economic and reliable material for home pilings. A larger
friction surface and non-corrosive material enables Accu-Pier
to protect its customers against
future repairs by offering a no-cost, lifetime warranty.
Myth 3:
A single pier pressed
piling system is good enough for any home or structure.
Fact:
A single pier piling is good enough for some single story brick, and most single
story frame home. A dual-pier repair is recommended for ALL brick homes and some
frame homes. With the dual-pier, you get twice the coverage on the foundation
beam, and twice the product in the ground, all for a very comparable price. 2 is
ALWAYS better than 1.
Myth 4:
Pointed or spiral pier caps drive deeper into the sub-strata.
Fact:
Pointed pier caps might go 1-2' deeper (not proven consistently), but they keep
driving with every season change, resulting in failure of the pier system. When
the ground gets hot and dry, the clay shrinks and leaves the house setting on
the pier. With the weight of the home on the pier, the pointed cap at the bottom
has a tendency to drive into whatever it is setting on, be it rock or heavily
compacted soil. By using the flat bottom cylinders, we compact and compress
every thing on our way to solid sub-strata. That compaction under a 6" diameter
surface is the key to building the necessary resistance to insure future
support.
