Baseplate-mounting procedures
Prepare the baseplate for mounting
This procedure assumes you have a basic knowledge of baseplate and foundation design
and installation methods. Follow industry-standard procedures, such as API RP 686 together
with this procedure before you grout the baseplate.
Make sure that all baseplate surfaces that will contact grout are free from contamination such
as debris, paint or preservative. Thoroughly clean all baseplate surfaces that will come into
contact with the grout. Be sure to use a cleaner that will not leave any residue.
NOTICE:
You may need to sandblast the surfaces of a baseplate that come into contact with the grout,
and then coat those surfaces with a primer that is grout-compatible. Refer to the grout
manufacturer’s instructions for guidance. Remove all equipment from the baseplate prior to
sandblasting.
NOTICE:
Remove all dirt, paint, preservative and debris from the mounting pads in order to ensure that
the correct leveling is achieved. Failure to do so can result in equipment damage or
decreased performance.
Make sure that all machined surfaces are free from raised edges, burrs, rust, paint, or any
other type of contamination. If necessary, use a file or grinding wheel to remove raised
edges or burrs.
