FLOORING
The Department of Defense( DoD) mandates that no bare concrete flooring be used in manufacturing facilities and flooring requires regular maintenance. Leewens has contracted with Boeing to ensure compliance with federal regulations.
TANKS
For a variety of tanks in the manufacturing plant, such as anodizing tanks, the liquid materials must be safely contained. Also, the area around the tanks must be impervious to any spills. When liquids or materials become waste products, they must be placed in another lined tank for storage until they can be disposed of safely. Leewens provides the appropriate tank lining services. This may include polystyrene( a synthetic polymer) plastic liners, which protect tanks and concrete structures from chemical attack; wastewater containment in plastic-lined lagoons can serve as primary and secondary containment.
STRUCTURES / FACILITY REPAIRS
Leewens contracts to address issues for employee parking garages and structures, as well as facility repairs. From cracks in concrete to reinforcing structural columns with carbon fiber wraps to protect against earthquakes, Leewens is brought in to provide services that will last for decades. They can also help strengthen concrete structures, such as bridges. Patrick said that while carbon fiber is used in the manufacture of aerospace components in a highly controlled indoor environment, the real challenge is in using the material for outdoor structures. They coat bridges, highways, roads, parking garages, and office buildings where heavy equipment resides. Patrick noted that while there are waterproof products, the company also needs to consider factors such as bridging cracks under chemical exposure( such as nitric and sulfuric acid, etc.) and utilizing specialty coatings for metal processing in aerospace and defense. He said,“ Aerospace uses chemical milling( etching the weight of seals on aircraft) and anodizing( making metals corrosionresistant).” These things affect how they prepare surfaces for the production of parts.
