The uptown campus of The University at Albany, State University of New York bears the unique post-modernist design of Edward Durell Stone, replete with curving arches, slender modern columns open spaces and fountains.  Central to the design is raw concrete and its organic nature.  Composed of four dormitory quadrangles framing the center academic podium, each quad has its own 24 story tower surrounded by low-rise residence halls.  The residence halls and academic podium are protected by large concrete canopies, the towers are not protected and showed signs of wear after decades of exposure.  This renovation project will restore and repair the tower surfaces to ensure the continued long life of these important structures. Scope of the renovation included concrete repairs and to protect the concrete and steel structure while maintaining the original concrete color and finish.  When completed the towers will be much more uniform and not “blotchy”, but more importantly the concrete surfaces will repel water and help ensure their long life.  

From Keim:

Once concrete was repaired the surface was treated with Silan 100 Water Repellent Finish and immediately followed by two coats of Concretal Sol Silicate Pigmented Stain in two colors.  Unique colors were chosen for the cast concrete components and the precast concrete fins, to match the original design intent of the architect.  Many mock-ups were installed for both water absorption testing and aesthetic approval before final approval was granted by the University and DASNY.
