The most important features that distinguish a cleanroom floor from a normal industrial floor include:
– Low abrasion
– Crack-free
– Easy cleaning and disinfection
Of course, depending on the application, there is also conductivity, high load-bearing capacity, resistance to chemicals and much more.
However, as always when it comes to cleanrooms, it is particularly important that the floor coverings emit few particles and that the installation does not allow any hidden dust deposits.
As a rule, this is achieved using 2K epoxy coatings or certain PVC plastic floor coverings. Other floor types are also available for special applications.
- The 2C floor has a high load-bearing capacity and is therefore almost always used when heavy equipment is installed or rolling loads are caused by transporting materials with pallet trucks. As a rule, the coating is applied before the cleanroom is built for better installation. However, a relatively long drying/curing time up to the final Shore hardness after 28 days must be taken into account.
- PVC flooring has a much lower load-bearing capacity by nature. This means that driving grooves can form and imprints can occur where machines are located. However, it has clear ergonomic advantages for staff and could even be recycled.
PVC flooring can be laid before the cleanroom is built or afterwards – in the latter case, the Cleanroom is simply raised by the height of the flooring and the flooring is then “tucked” under the plinth profile. After the floor has been laid, there is no sign of this “trick” ?
Incidentally, in our cleanrooms we prefer to lay the cleanroom floor before installing the cleanroom system. The Cleanroom is then installed on the prepared floor. The floor connection between the floor and wall is made using a small coved joint, which is easy to clean with a mop.
What you should avoid in any case are concrete floors, carpets or rammed earth floors … we have also experienced this ?
