Pratt & Whitney Test Cell Expansion

Scope of Work

New construction to increase Pratt & Whitney’s ability to assemble, rebuild and test civilian jet engines.



Developing the specifications for an epoxy coating system in a 10 Meter Jet Engine Test cell.

The system must be able to withstand stresses produced by up to 90,000 pounds of jet engine thrust and up to 5000 pounds-per-second of airflow.

Additionally, the floor must be able to withstand prolonged exposure to purging fluids.


Installation Process

Following the specifications, the floors were mechanically ground with planetary grinders. Joints were routed with diamond discs.

Three coats of respirable epoxy were applied to prepared substrate, routed joints were filled with polyurea joint material and shaved. A top coat of respirable/chemical resistant urethane was applied.
