While the cost of materials used in cleanroom construction is always a concern, the durability of those materials is far more of an issue because of the high cost of repairs once the cleanroom is in operation. For example, if the flooring cracks or loses its ability to contain spilled chemicals, it may be necessary to tear up the finish, repair the cracks, and install another floor.
Making this kind of repair while trying to maintain production in the cleanroom by isolating the section under repair with heavy drapes is very expensive. Even then, the cleanroom atmosphere is in jeopardy with the first blow of a jackhammer or the removal of a piece of equipment.
In cleanroom construction, it is imperative that the job be installed correctly the first time. Flooring system problems are most often related to poor installation, and it is prohibitively expensive, if not impossible, to correct installation defects without adversely affecting the operation of the cleanroom. Due to this concern, we typically specify that the installed product be warranted by the manufacturer.
