Fallingwater Strengthened

When one of America’s most treasured landmarks experienced severe cracking and defl ections, the Western Pennsylvania Conservancy added VSL to the team to help restore and strengthen Frank Lloyd Wright’s Fallingwater. Completed in 1939, Fallingwater is comprised of a series of concrete cantilever “trays” 30-ft. above a waterfall. Previous efforts failed to permanently address excessive defl ections of the cantilever and repair the cracks. After a thorough design review, the owner and engineer selected an external post-tensioning solution for its durability, aesthetics and structural unobtrusiveness.

Winner Takes All

The adage “time is money” is certainly relevant to many industries as it relates to building renovations and the cost of downtime, interruptions to services or inconveniences to customers. To the casino industry, the phrase is even more literal. Any interruptions to revenue generating operations come at great expense to the owner.
That is why Perini Building Company -- the largest builder of hotels and casinos in the United States and general contractor for new construction and renovation of the Resorts International Casino in Atlantic City -- and the owner of Resorts Casino looked to create a team that could bring together both engineering and construction expertise for a critical path concrete repair and strengthening project. They assembled a team that included Structural Group -- one of the nation’s leading specialty contractors in concrete repair -- and Lochsa Engineering -- one of the premier design groups for casino construction and renovations.

Steel-Belted Flooring: Concrete Flooring is Strengthened by Polymer Technology
By: Editor - Saturday, July 15, 2006
Source: strengthening.com
For more than 40 years, various forms of polymer based flooring systems have been successfully applied to concrete surfaces. These systems have become mainstream forms of protection against aggressive chemicals, abrasion and impact while also offering an appealing aesthetic appearance. However, there is a movement to further enhance polymer based flooring systems as the need for improved structural capacity increases on our industrial floors. In reality, material handling equipment is getting heavier, buildings are experiencing loads for which they were not originally designed - including loads from potential explosions - and floors are being taxed beyond their capacity.
