Concrete's strength and versatility have made it a popular building material. Since ancient times, it has been used in everything from practical structures to culturally significant buildings and grand monuments. Despite its timeless virtues, aging concrete, such as that found on historic structures, can be vulnerable to deterioration, causing structural damage and loss of character.

Natural aging and exposure to water causes deterioration and leads to cracking and spalling that can expose reinforcement. Corrosion of embedded steel weakens and compromises concrete structures. Expansive forces of corroding steel cause concrete to fracture and break apart. Efflorescence and alkali-silica reactions can further damage the concrete.

In response to these conditions, inadequate repairs generally only worsen issues. Inappropriate changes to the original finish impact the structure's historic character. Addressing these factors when preserving landmark concrete structures is vital to a sound preservation program that is guided by the Secretary of the Interior’s Standards for the Treatment of Historic Structures.

TTG is uniquely experienced in concrete restoration and has played a critical role in preserving the character, structural integrity and historical significance of historic buildings across our nation.
