Indicator smoke was injected under the VIMB, and leaks were patched until no smoke was visible. But implementing it in the field, especially under poor weather conditions can be an entirely different thing. And/or ground water to reduce or eliminate the contamination source.

Passive Sub-Slab Depressurization System Design Studio

"Radon Chamber" means a facility in which radon measurement devices or detectors are exposed to known radon concentrations. They are also used to. It is excellent for smoke test because you're essentially building the barrier as you go in place and so when you're doing the smoke test and you have a failure, it is very easy to fix that failure and move on. I'll be continuing the discussion of some of the same topics Mark just discussed, specifically construction considerations for vapor barrier installations. Systems may provide little help. On average, our design strategy reduces installation costs by 40-70% compared to spray applied systems. Passive sub-slab depressurization system design tools. So, I guess, there are really two ways I can answer this question, whether that's building type or type of contamination. The electret charge is read before and after the exposure using a specially built non-contact electret voltage reader. Again, I use tape systems sometimes, but it is a pain in the butt to pass a smoke test because that butyl tape has to be 100% flat. But then we also had secondary smoke tests so that after the barrier was placed, and then the geotextile was placed, then the stone went on top. And I think highlighting what goes into durability of any vapor barrier is incredibly important. All of these things will happen on or near the vapor barrier whether you like it or not.

An important note is both buildings were speculative, which means they had no tenants when they started to build it. So, for context, the first building is about 575, 000 square feet. And it has like a two-sided tape, a butyl seam tape and also a one-sided tape that they use. And it's something regulators, design engineers, consultants often look at first. So that's where the way we went. But you know, that might have been the case a long time ago. Your project maybe be located where it rains on a daily basis. Indoor vapors arising from subsurface contamination. And so we were able to really get some nice production capacity. Ryan: Thanks, Mark, really great information there. This system relies primarily on the convective flow of warmed air upward in the vent to draw air from beneath the concrete slab.

"Passive New Construction Pipe" or "PNC" means a pipe installed in new construction that relies solely on the convective flow of air upward for soil gas depressurization and may consist of multiple pipes routed through conditioned space from below the foundation to above the roof. And with a spray-applied system, you can fix it by spraying more and basically just building more barrier up and covering and sealing it.
