When installing Concrete Sinks in a Commercial Bathroom the ADA requirements must be met. These Double Integral Sinks were made for a local university in Pittsburgh PA at their Alumni Hall. It was a commercial project that had to meet ADA dimensions and installation heights. The overflow technique used on the sinks was taught by Buddy Rhodes in San Francisco, Thanks Buddy! The sinks were installed in one piece with a 4" backsplash also made of GFRC.
Side Note: The project in photo was fabricated and installed - Start to finish - in just 4 days! No other method could give us the early strength that GFRC did!
