Seattle, WA – The Stadium Place Embassy Suites Hotel in Seattle could not have a better location. The Embassy Suites is next to Century Link field, home of the Seattle Seahawks and the Seattle Sounders, as well as the city’s central public transit hub. The hotel provides a panoramic view of the city in one direction and Mount Rainier in another. The Hilton chain expects this 282-room hotel to become their flagship Embassy Suites Hotel in the United States. Emerald City Sealants & Waterproofing LLC is using Sika products to waterproof this important building.
Rob Clark from Emerald City has been using Sika products since 1975. He is currently working with his son to apply Sikalastic 621 TC RoofPro on the roof and patios of the Embassy Suites. Rob explained to us that from his experience Seattle is “super saturated” with water. According to him, that means that when something gets wet it tends to stay wet. Because of this, the single-component, moisture-triggered Sikalastic 621 is useful as Rob doesn’t have to worry if it starts to rain shortly after application. Between the 23-story Embassy Suites and the neighboring 18-story North Lot Development building, there is over 50,000 square feet of roof that needs waterproofing.
When I asked Rob whether the area was flood prone, he couldn’t help but laugh. He told me that the area was actually tide prone, as the water level of the nearby Elliot Bay is five feet above the ground floor. To account for this, sheet piles were driven and welded around the foundation of the building, providing a barrier to retain soil and water. Cryosol, a type of waterlogged soil, was pumped out and a concrete barrier containing Sika Greenstreak PVC Waterstop was put in. Rob designed the 32,000 lineal feet of Waterstop to ensure the tide stays on the right side of the building. With the teamwork of Rob Clark and Sika’s Kevin Vaughn, the water in this super saturated city will be nothing to worry about.
