4.2 Baseplate-mounting procedures
4.2.1 Prepare the baseplate for mounting
This procedure assumes you have a basic knowledge of baseplate and foundation design and installa-
tion methods. Follow industry-standard procedures, such as API RP 686/ PIP REIE 686, or this proce-
dure before you grout the baseplate.
1.
Make sure that all baseplate surfaces that will contact grout are free from contamination such as
rust, oil, and grime.
2.
Thoroughly clean all baseplate surfaces that will come in contact with grout.
Make sure to use a cleaner that will not leave residue.
NOTICE:
You may need to sandblast the surfaces of a baseplate that come in contact with grout, and
then coat those surfaces with a primer that is grout-compatible. Make sure to remove all equip-
ment before sandblasting.
NOTICE:
Remove all dirt 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.
3.
Make sure that all machined surfaces are free from burrs, rust, paint, or any other type of contami-
nation.
If necessary, use a honing stone to remove burrs.
4.2.2 Prepare the foundation for mounting
1.
Chip the top of the foundation to a minimum of 25.0 mm | 1.0 in. in order to remove porous or low-
strength concrete.
If you use a pneumatic hammer, make sure that it does not contaminate the surface with oil or other
moisture.
NOTICE:
Do not chip the foundation using heavy tools such as jackhammers. This can damage the
structural integrity of the foundation.
2.
Remove water or debris from the foundation bolt holes or sleeves.
3.
If the baseplate uses sleeve-type bolts, then fill the sleeves with a non-binding, moldable material.
Seal the sleeves in order to prevent the grout from entering.
4.
Coat the exposed portion of the anchor bolts with a non-bonding compound such as paste wax in
order to prevent the grout from adhering to the anchor bolts.
Do not use oils or liquid wax.
5.
If recommended by the grout manufacturer, coat the foundation surface with a compatible primer.
4.2.3 Install the baseplate using jackscrews
Tools required:
•
Anti-seize compound
•
Jackscrews
•
Bar stock
•
Two machinist's levels
