Electrochemical Treatments on Historic Steel Frame Buildings

The American Institute of Architects, March 2008

Corrosion is present in historic buildings which utilize iron or steel in construction and can cause a variety of failures leading to masonry damage, the loss of original fabric, and even death. Traditional repair techniques can temporarily slow the corrosion process but do not provide a long term solution for corrosion.

Corrosion - Hidden in Plain Sight

Hydrocarbon Engineering, March 2008

Besides the catastrophic consequences associated with manmade (i.e., fire and explosions) as well natural (i.e., tornadoes and hurricanes) disasters, long-term degradation of the infrastructure should be anticipated and scheduled maintenance planned well in advance to keep costs low and infrastructure dependability high.

Balcony Repair: Long-Range Approach Is Best

Florida Community Association Journal, February 2008

A typical concrete balcony in Florida, constantly exposed to the harsh coastal elements, is a breeding ground for deterioration. As such, condominium owners and associations often find themselves in the middle of balcony repair projects. All too often, though, a shortsighted approach to balcony restorations is taken, and only minimal repairs are made at one time. As a result, owners fail to realize the practical and economic benefits of a more long-range approach to balcony repair.

Maintaining Masonry - Repair Beyond Caulk

Construction Specifier, February 2008

The image of any building constructed with masonry typically conjures thoughts of a structure designed for permanence and durability - a construction so sound that it will last through many decades. After all, masonry structures dating to ancient times still stand tall in many places all over the world. Yet over time, even the most soundly designed and constructed masonry buildings require some attention. Extreme weather conditions and the general effects of time may lead to a need for masonry repair. Or, in some cases, poor building design or construction may be the cause.

From Eyesore to Opportunity: Adapting an Older Building for a New Use

Architectural West, January / February 2008

It is inevitable that structures will age and outgrow their original intended function. With changes in technology and lifestyle, construction design is constantly updated to meet modern demands and older structures are left in the wake of change. Those sensitive to history may prefer to restore older structures to their former glory, however, associated costs often make this plan unrealistic. An alternate concept is adaptive reuse - a process of retrofitting buildings for new uses, which allows structures to retain their historic integrity, while providing for the occupants' modern needs.

Corrosion-Induced Deterioration: Repairs and Protections

Power Engineering Magazine, November 2007

As the supply source for operations in power generating plants, water intake structures serve an important function. Because of the constant exposure to water - whether fresh, brackish or marine - these intake structures are extremely susceptible to corrosion-induced deterioration. However, with an understanding of the root cause for corrosion-induced concrete deterioration and the technologies available to address it, plant and maintenance professionals can adopt the proper mechanisms and rehabilitation strategies.
