Xypex Waterproofing in Foundations

The use of concrete as a design element has always appealed to architects. However, concern over water seepage, efflorescence and rebar corrosion has often held them back. Faced with this issue, Joseph Bellomo Architects used the crystalline waterproofing and protection features of Xypex in an innovative concrete mix on their new LEED Platinum project in Palo Alto, California. A 70% slag concrete mix combined with Xypex Admix was used for the 3,600 cubic yards required for the six-story building’s façade.

Joseph Bellomo, principal architect, reported that, “The slag/Xypex combination created the densest, most durable, waterproof concrete that we’ve yet been able to produce. There is no porosity and no signs of efflorescence in the concrete. It is ideal for indoor/outdoor facades, integrated drip edges and tight reinforcement.”

Registered with a LEED certification goal of Platinum this structure, located along California’s central coast at 102 University Avenue in Palo Alto, is expected to provide a sustainable, energy efficient environment – come rain or shine.
