This report provides an overview of current practices for
grouting to support equipment and machinery. Recommendations
are provided for those portions of the grouting operation
where a consensus could be developed among knowledgeable
manufacturers and users. Various approaches are
outlined for areas where opinions differ. Many statements
and much of the information contained in this report are
based on published manufacturers? data and observations
and practical experience by technical representatives and
users. There is little current published research available at
this time, but the information in this report is the most current
information available. This report describes materials and
installation methods for grouts used as load-transfer material
between machine or equipment bases and their foundations.
Characteristics of the placed material, test methods
for forecasting their long-term performance, and installation
procedures are included. The information may also be
appropriate for other types of applications where filling of
the space between load-carrying members is required, such
as under column baseplates or in joints between precast
concrete elements.
Machinery and equipment that have precise tolerances
for alignment or require uniform support cannot be placed
directly on finished concrete surfaces. Both the concrete
surface and the machine base have irregularities that result
in alignment difficulties and bearing load concentrations.
For this reason, machine bases or soleplates are aligned and
leveled by shimming or other means, and the resulting space
between the machine base and the foundation is filled with a
load-transfer grout material. The load-transfer grout materials
most frequently used are nonshrink cementitious grouts and
nonshrink epoxy grouts.
