| Magnum Piering,
Chimney Repair | Case Study |
Project: Repair a two-Story chimney that was leaning
away from the house
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. |
