Lift a Building, EASY
Chance HELICAL PIERS are installed
using portable hydraulic equipment to a specific torque value.
This torque value equates to a specific bearing capacity.
This is proven with thousands of tests nationally. Chance
Certified Installers place a safety factor of a minimum of 2 to1
on every pier that is installed. This ensures no problems in
the future. This is one of the problems with piers that are
installed by using the weight of the home to push the pier down.
There is no safety factors built into this type of system.
Knowing the capacity of the pier,
the capacity of the structure and building in a safety factor, it
is easy to place hydraulic jacks on top of the piers and lift the
structure.

| Every pier which
McCloy Construction installs, we load test the piers by placing
hydraulic jacks on top of the pier to ensure there are no
problems an to lift the structure off the poor soil. Once
there is a gap between the soil and the concrete footer, it is
known that 100% of the weight of the structure is held by the
piers. This allows the inadequate soil under the structure
to settle, creep downhill, or shrink during dry months, without
effecting the foundation. This picture shows the gap
between the footer and soil.
McCloy Construction has lifted
corners of structures, as well as entire front or back halves.
WE have lifted and entire building which was built on fill.
57 piers were placed around a 40' X80' building. On top of
these piers we placed hydraulic jacks and lift the building
enough to have a local engineer place his hand under the footer.
A newly constructed home was
built with the front right corner on fill. Before the
contractor completed the home, the corner was settling and
cracking. We lifted this portion of the home over 4 inches
to place the foundation back to its original position.
