Veolia Water Technologies
Lab and Office Re-roof
Salas O’Brien used expert design to resolve a long history of roof leaks and a partially collapsed ceiling for these water treatment specialists.
Our client
Veolia Water Technologies is a leading specialist in water treatment. Their teams design and deliver drinking water or wastewater treatment plants as well as smaller standardized water treatment equipment for industrial or municipal customers.
Their challenge
A long history of leaks and a partly collapsed ceiling prompted this client to contact us. The roof on this one-story concrete laboratory and office building was riddled with mechanical equipment, incomplete repairs, corroded and mislapped flashings, eroded duct seals, and weathered caulking.
Our solution
Working diligently to finish before the winter rains set in, our team collaborated with the owner’s contractors and maintenance crew to identify efficiencies in mechanical equipment, eliminate unused or obsolete equipment, improve drainage, and vastly simplify the roof design for the new installation.
The results
Today the roof is leak free, drains well, and has more efficient insulation, durable caulking, OSHA-compliant ladder access, and a 20-year warranty from the membrane manufacturer.
