Retro-Coat™ Applied to Former Jazz Club Ensures Protection from Vapor Intrusion

Video Transcription

Narrator: Renton, Washington, founded in 1901 and named after Captain William Renton, a wealthy businessman who made his fortune in coal and timber. Renton is a bedroom community outside of downtown Seattle. Now home to the Seattle Seahawks practice facility, the second largest facility of its kind in the NFL. Many know the greater Seattle area as the epicenter for the start of grunge rock in the ’90s, and the home to the original Starbucks coffee. As a suburb to downtown Seattle, Renton has seen tremendous growth over the last two decades, as technology giants like Microsoft, Amazon, and Nintendo choose the area for their global headquarters. With commercial properties and home values ever increasing, developers are looking for new ways to restore brownfield sites quickly and effectively, to allow them to move forward with future development. In the case of a former popular jazz club in the historic section of downtown Renton, indoor air quality was impacted with volatile organic compounds associated with dry cleaning solvents that had spread from a nearby dry cleaning operation.

Denny: The site is located right downtown in Renton. It’s got parking and all kinds of things, a lot of open space. It has a total of about 7,300 square feet of space. The foot print’s about 5,300. It’s a real good quality building that’s been contaminated by the neighbor’s dry cleaner.

Narrator: Concentrations of PCE and carbon tetrachloride, primary contaminants of concern exceeded the Washington State Department of Ecology risk screening regulatory level of indoor air quality.

Denny: I wanted to make it safe to inhabit the space because there was major vapor intrusion, so I could only not sell it, but I couldn’t lease it.

Yen: We need to turn around, we need to find a solution that is active but also a long-term solution. In terms of remediation approach, we could either put in…install a sub-slab depressurization system, or else use the Retro-Coat, you know, Vapor Intrusion System. And in talking to Land Science, that was one of our options. And so we did a cost analysis for, the Retro-Coat Vapor Intrusion System’s about a third less of the cost.

Thomas: Their goal was how do we protect the public from this. So meeting and talking with and meeting with and talking with over conference calls with a developer, you know, we’re looking at the options of having this Retro-Coat be a be-all-end-all solution for Vapor Intrusion.

Narrator: Land science recommended it’s proprietary Retro-Coat Solution, a patented, odorless, fast-curing epoxy surface proven to effectively mitigate vapor intrusion. Retro-Coat has been tested and proven resistant to chlorinated compounds such as TCE, PCE, and petroleum hydrocarbons. Retro-Coat eliminates the need to remove existing slab or concrete foundations.

Yen: I like a lotta things, working with Tom and the Land Science team, the REGENESIS team in general. They’re experts in their field, very responsive, and very patient in terms of us asking, what do we take to get this work done in three weeks? Was that really viable? And I’m happy to say that all of that materialized just like what Tom and the team…Tom’s team has stated that would be. And ultimately, we have a happy client.

Denny: I have been very pleased that Yen has worked closely with me and oh, we decided on this, it happened very quick. And so I’ve been very pleased with everyone that’s…I’ve been involved with. There’s no more vapor intrusion, and so it’s just a matter of marketing the place and selling it. And I can do that with a clear conscience, which is what I like.
