The biggest and worst is the crawl space we dried out a few months back.
There was 20,000 sq/ft wet and over 250,000 gallons had poured into it the crawl space and a wrestling room at a local High School from a broken water main.
We used 3-TES units to dry it out, moving from dry areas to wet areas. Most sections dried in a couple of days with the majority of the job done in 8-days and 1-TES was left to dry the break area for 2-additional days.
We've saved a lot of difficult to dry materials, plaster, double sheet rock, hardwood floors using TES. It's faster than any other system we've used.
Ask Craig, he had a crawl space that was thick with ice that he melted and dried in the middle of a cold winter. Amazing pictures!
