CASE STUDY: Beast ® Foot

Beast Foot Helps Keep Graton Casino Resort Expansion Dry

At the Graton Casino in Rohnert Park, California, the one thing they didn’t want to gamble on with their new expansion was a moisture problem. For Urata & Sons Concrete, Inc., this meant finding a whole new way to support and brace interior forming while maintaining the integrity of the vapor barrier below the concrete. Not doing so could cause excess moisture in the new 200-room hotel, due to open later this year, which could be bad for the overall health of the project. This required new thinking. What Urata needed, it turns out, is Beast Foot. Urata & Sons have been in the concrete business for over 40 years, including membership in the American Subcontractors Association, the Sacramento Area Trade Organization, and others. Their experience and expertise are what earned them the hotel expansion job, and the work on the site “includes structural concrete foundations, slabs

on grade, concrete shear and core walls, cast-in-place podium decks, columns as well as the exterior concrete paving flatwork curbs and other site work.” It was a big job, and when it came time to place concrete over the va por barrier, they looked for ways to set their interior forms without puncturing the vapor barrier. Protecting the Stego ® Wrap Vapor Barrier Urata & Sons had installed Stego Wrap Vapor Barrier and were pouring concrete over it, which brought up their first challenge: The Challenge: When preparing to set their interior forms, they would normally use form stakes, but this would require creating holes in the vapor barrier. Repairing these holes once concrete is poured is not feasi ble. The first pour alone required approximately 250 cubic yards of concrete. Urata estimated that this would create hundreds of holes in the vapor barrier.
