"I AM AFRAID THAT MY CHIMNEY WILL COLLAPSE!"
A Claremore, Oklahoma, homeowner was very concerned that the chimney on the side of his
house would come crashing down and injure someone. The movement of the chimney had allowed
a family of sparrows to take up residence in the attic.
The homeowner went on to say that stains were visible on the ceiling. The flashing
connecting from the chimney to the roof had failed and rain was penetrating the roof.
Could the chimney be saved, or must it be torn down and a new chimney built?
Before
Restoration and After Restored with ATLAS RESISTANCE PIERS
Atlas Piers of Tulsa, Inc. installed eight ATLAS RESISTANCE PIERS around the
chimney and along the adjacent perimeter wall. Not only did the ATLAS RESISTANCE PIERS
provide stabilization, the piers were used to raise the foundation one inch to
restore the chimney to vertical and to level the foundation.
THE SOLUTION: ATLAS RESISTANCE PIERS!
STABILIZED AND RESTORED THE
CHIMNEY AND FOUNDATION!

Atlas Resistance Piers
Lift Force vs. Drive Force & Ultimate |
|
| The chart above shows the ultimate
pier capacity is over four times the average pier load. The average driving force
is over 60 percent above the average pier load. |
This ten
year old house is constructed upon continuous spread footing with stem wall at the
perimeter. The exterior wood siding and the chimney is constructed of masonry.
Atlas Piers of Tulsa, Inc. installed Atlas Resistance Piers around the chimney
and adjacent perimeter footing in order to stabilize and restore the structure. The piers
were driven to a bearing stratum at a depth of approximately sixteen feet. The restoration
process removed one inch of settlement and returned the chimney to vertical!
This photograph shows the
two Atlas AP2S-3500 Piers used to restore the chimney. The hydraulic rams are actuated
together and are used to lift the structure. Once restored, the rams are removed.
