Project
Repair a two-Story chimney that was leaning away
from the house
Job
Description
The
Two-Story fireplace had leaned
away from the side of the house with an
overall lean of 16” at the top of the structure. This
resulted in masonry veneers separating and cracking along the adjacent
walls.
The chimney
needed to be raised, realigned, and stabilized.
Solution
Four 3” Diameter Magnum Steel Piers with Heavy
Duty angle brackets were installed in order to raise, realign, and
stabilize the leaning fireplace.
One additional pier was installed at the adjacent corner of the
house because it also showed signs of distress.
A pressure gauge was used to monitor drive pressure during the
installation of each pier. The
final average drive pressure was 4500psi.
This resulted in an ultimate 37 kip capacity.
The average pier drive depth was 33'.
Results
The
lift went extremely smooth.
A lean
correction of 13” was achieved
before
small debris between the fireplace and masonry profile prohibited
additional correction.
The
adjacent masonry was repaired and repointed to provide a fireplace and
wall veneer system with no visual blemishes.
Cost
Savings
This solution of piering and masonry repair
method provided a cost savings of $7000 over removal and replacement
as proposed by other contractors.
