Do you need a special cleanroom floor?

This topic always raises questions... We would like to give you a brief overview based on our practical experience.

The main characteristics that distinguish a cleanroom floor from a normal industrial floor are
- Low abrasion
- Crack free
- Easy to clean and disinfect

 
Of course, depending on the application, there is also conductivity, high load-bearing capacity, chemical resistance and much more.
However, as always with cleanrooms, it is important that the flooring is low in particle emission and that the installation does not allow for hidden dust deposits.

This is usually achieved with 2-component epoxy coatings or certain PVC plastic flooring. Other types of flooring are available for special applications.

  • The two-component floor has a high load-bearing capacity and is therefore almost always used where heavy equipment is installed or where rolling loads are generated by the transport of materials with pallet trucks. The coating is usually applied before the cleanroom is constructed to facilitate installation. However, a relatively long drying/curing time to final Shore hardness of 28 days must be taken into account.
     
  • PVC flooring has an inherently lower load bearing capacity. This can result in ruts and indentations where machinery is positioned. However, it has clear ergonomic advantages for staff and could even be recycled. PVC flooring can be installed before the cleanroom is built or after - in the latter case, the cleanroom is simply raised by the height of the flooring and the flooring is then 'tucked' under the skirting. 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 connection between the floor and the wall is made with a small coved joint, which is easy to clean with a mop.

What you should avoid at all costs is concrete floors, carpets or rammed earth floors... we have experienced this too 😊.
