The original applicator was basically just applying the foam to the surface and not with the intent of allowing the roof to drain properly,” he said. “And so my crew came in and we corrected all of the ponding issues, repaired all of the delaminated foam, and pretty much renewed the roofing system to our standards.”

When it comes to wastewater treatment plants, grit tanks are important components that rid the influent wastewater of solids, such as road sand and other debris. “At the Manchester, New Hampshire Wastewater Treatment Plant, wastewater is dropped into large tanks with air diffusers that work to decrease the density of the influent.

Have you ever heard people in your workplace make statements about safety that just don’t ring true? Often these are not lies or half-truths; they are simple misunderstandings rooted in unsubstantiated beliefs.

Metaphors for breaking records abound, and patience for “limited thinking” is in short supply. So when someone who’s flown combat missions over Vietnam and broken world aviation records talks, you listen.

According to Jeff Kennedy of Applied Coatings and Restoration, the relatively new building was showing substantial cracking throughout the concrete concourse ring above the arena floor and also in the ticketing and main entrance area. “The concrete deck was extremely cracked; it looked like a road map.

The floor needed to have high wear resistance, impact resistance, ultraviolet (UV) stability, and thermal shock resistance. It needed to counter pooling water and be nonporous. It was a tall order, and on top of all of that, “in a facility that’s surrounded by glass, it needs to look its best at all time,” Winters elaborated.

The building had metal walls that were not insulated and there was no functional heating system. That was not going to work, so the company looked into its options and ultimately settled on spray polyurethane foam (SPF), also referred to as spray foam, and intumescent coatings.

Lately, safety practitioners seem to be on a quest similar to that of King Arthur and his Knights of the Round Table. But instead of trying to find the Holy Grail, safety professionals are trying to find something similarly elusive: a single, all-encompassing, leading indicator upon which they can manage their entire safety function.

An eye catching project can be a real sense of pride for the community, and cities that don’t even put letters or logos on their tanks are missing a golden opportunity. True that it’s a little bit cheaper, but they’re missing out on advertising the quality of their city.”

With motorists above, a girder of the then 28-year-old bridge in Milwaukee, Wis., started to crack and sag. Although no injuries occurred, the steel arch bridge was closed immediately and repairs started soon after.
