Machine units that do not share a common baseplate and require alignment to other units should not be mounted directly onto a foundation. They are set and fastened to:

When machine units that do not share a common baseplate are required to be aligned with other units, it's essential to provide a method for their secure installation while allowing for potential adjustment and alignment. Fastening these units to grout provides a flexible, generally non-rigid support that can accommodate imperfections in the foundation and the minor shifts that might occur during operation.

Grout allows for some degree of movement or adjustment, making it suitable for these types of installations, as it can fill gaps and provide a level surface that can help with alignment. This is particularly important when precise alignment is critical for the operation of connected machinery, as direct mounting could lead to misalignment over time due to vibrations or thermal expansion.

In contrast, other choices such as bedplates, foundation plates, and soleplates typically imply a more rigid mounting system that may not be appropriate for machinery requiring ongoing alignment adjustments. While these options can provide stability, they do not offer the same flexibility and adaptability as grout, making it the ideal choice for this context.
