Facade
Restoration: Rehabilitating Unstable Veneers by Steve Getz
The cladding on buildings throughout the United States, large and small,
single story and high rise, is continually exposed to stresses and strains.
In order for a building to maintain its exterior structural integrity
and aesthetics, design details and recommended construction practices
must be faithfully executed. Conditions that result in forces or wall
movements not anticipated in the original design can create eithe cosmetic
or castrophic problems. pdf [4.1 mb]
Solving
Problems Through Reanchoring by Steve Getz
Weather and other corrosive influences can take a toll on the original
anchoring systems of primary building structures. To combat this problem,
ITT Phillips Drill Division has devised ways to resupport the facades
of projects in several states
Each project required the anchoring
of a facade to concrete or masonry substructures. In one instance, the
loss of support resulted in a marble panel fallinf several floors to a
sub-roof area. No one was injured, but the owners were concerned for the
safety of occupants and pedestrians.

Repairing
Limestone Cladding
- Corroding anchors and spalling limestone at the mail Philadelphia
store of Strawbridge and Clothier promoted a simple and cost effective
repair program
One of the most frequent encountered masonry deterioration problems is
spalling, a loss of surface materical that does not affect structural
integrity. Typically caused by a variety of processes, including freeze/thaw
cycling and the expansion of corroding iron or steel fasteners (called
oxide-jacking), spalling is disfiguring and potentially dangerous to building
occupants and pedestrians.
