PART 2-PRODUCTS
2.1-Grouts
Supply grout as specified in Contract Documents.
2.2-Joint and sealant material Supply joint and sealant material as specified in Contract
Documents.
2.3-Formwork
Supply forms and formwork, including accessories, as
specified in ACI 30 1.
2.4-Water
Unless otherwise specified in Contract Documents, all
water shall be potable.
PART 3-EXECUTION
3.1-Preparation 3.1.1 Prepare concrete surface on which grout will be
placed to provide a minimum 0.5 in. peak-to-valley profile,
remove all laitance and microcracking from the concrete,
and expose coarse aggregate. Use only small hand tools or a
small pneumatic hammer with 30 lb maximum weight with
a moil or chisel point to generate the profile. Nail point tools,
bush or bush head bits, large jack hammers, or pavement
breakers shall not be used. The surface shall be thoroughly
cleaned and protected from subsequent contamination. The
concrete surface shall be saturated with water and main
tained in a saturated condition for a minimum of 24 hours
immediately before grouting.
3.1.2 Clear debris, dirt, and water from anchor bolt sleeves, shear key pockets, and other areas to receive grout
using oil-free compressed air or vacuum.
3.1.3 For anchor bolt sleeves that are not specified to be grouted, clear debris, dirt, and water by oil-free compressed
air or vacuum. Fill with nonbonding moldable materials as
specified in Contract Documents.
3.1.4 Install pins, dowels, or other means of controlling shrinkage cracks, edge lifting, or both, in areas of unre
strained grout as specified in Contract Documents.
3.1.5 The equipment base shall be inspected to ensure that grout can be placed beneath the plate without trapping
air in unvented corners. The inside of the baseplate shall
be inspected where possible for blind areas or obstruction
of flow. Verify that a vent hole l /4 to l /2 in. in diameter is
placed through the plate at the intersection of all crossing
stiffeners and at each point where air may be trapped.
3.1.6 Verify that grout holes for placement are located so that grout does not travel more than approximately 48 in.
The grout holes shall have been placed so that grouting can
be started at one hole and progress to other holes to ensure
that the grout flows under all areas of the plate. Verify that
holes for pumping grout are 3/4 to 2 in. in diameter and
threaded for standard pipe threads. Grout holes for gravity
assisted placement of grout should be 3 to 6 in. in diameter.
3.1.7 Verify that baseplate and other metal surfaces have been prepared in accordance with the manufacturers'
requirements for grouting.
3.1.8 Inform Architect/Engineer immediately if equipment base would create issues with grout placement.
3.1.9 Forms-Forms shall be rigid and sealed with tape, caulk, or similar material to prevent leakage. Forms shall
extend at least 1 in. above the highest elevation of the grout
material under the grouted element and shall be built so that
the grout can be placed as continuously and expeditiously
as possible. Forms may also be provided to prevent grout
from flowing over the top surface of the equipment base or
baseplate.
3.1.10 Form coating-Forms shall be coated with compatible form oil or wax or lined with plastic or other
suitable bond breaker or release agent. Do not allow form
work coating to contact underside of the equipment base or
concrete surface.
3.1.11 Gravity flow applications-When grout is to be placed around the perimeter of a base, the forms shall be
constructed so that a pressure head can be developed in a
headbox on one side of the plate. The headbox shall begin
2 to 4 in. from the baseplate and slope away from the plate
at approximately 45 degrees and provide a minimum grout
head of 12 in. The box shall be sealed to the form to generate
the head pressure required to get the grout to flow to the
opposite side. The form on the opposite side shall be 2 to 4
in. from the plate edge and shall extend at least 1 in. above
the bottom of the plate. On the side of the plate parallel to the
direction of grout flow, the forms shall generally be less than
1 in. from the plate but still allow air to vent from beneath
the plate during grout placement.

CEMENTITIOUS GROUTING BETWEEN FOUNDATIONS AND EQUIPMENT BASES (ACI 351.4-14) 5
To install grout through grout holes, use a placement cone
with a minimum grout head of 12 in. and sealed between the
cone and the hole edge.
3.1.12 Pumping cementitious grout-For placements where the grout will be pumped under the plate through grout
holes in the form, the forms shall be at least 2 in. outside the
plate edge on all sides. Minimum clearance under the base
plate shall be 1.5 in. The forms shall extend at least 1 in.
above the highest grout elevation under the plate.
For placements where the grout will be pumped under
the plate through a hose laying over the top of the form, the
forms shall be spaced outside the plate so that there is no
restriction of the grout flowing through the hose.
3.1.13 Corners-Round or chamfer all corners. 3.1.14 Expansion joints-Place expansion joints every 3
to 7 ft to intersect all inside or outside corners. Joints shall
run the full width of pour, length of pour, or both. Seal joints
with tape or caulk where expansion joint material abuts adja
cent material.
3.2-lnstallation 3.2.1 Unless otherwise specified, use mixers in accordance
with the manufacturer's written instructions or as described
in the Contract Documents.
3.2.1.1 The mortar mixer shall have a metal shell with horizontal mixing blades. The mixing blades shall be angled
so that adjacent paddle arms reverse the flow of the grout
in the mixing drum during rotation of the horizontal shaft.
The mixing blades shall have adjustable wiper blades that
wipe the inner surfaces of the mixing chamber. The wiper
blades shall be rubber or other flexible, wear-resistant mate
rial that does not deleteriously react with the grout mixture.
The wiper blades shall be adjusted to continuously wipe the
curved inner surface of the mixing chamber below the grout
level and the ends of the chamber. The horizontal shaft shall
rotate the mixing paddles at 28 to 35 rotations/minute.
3.2.1.2 The mixer shall be clean, prewetted, drained, and essentially free of hardened mortar and other foreign mate
rial that can be removed with a trowel or by striking with a
hammer.
3.2.2 Batch and mix grouts in accordance with manufacturer's recommendations. The water content or consistency
of the cementitious grout shall not exceed the maximum
or minimum values determined from qualification tests
or recommended by the manufacturer and shall not cause
bleeding or segregation in the mixed grout. The mixing time
shall comply with the manufacturer's recommendation. Place
grout as soon as possible after the completion of mixing.
If the grout must be held in the mixer after the completion
of the specified mixing time, the grout shall be agitated at
slow speed before dispensing. The time that a batch can be
held shall be within the limits of the manufacturer's recom
mendations. Placement shall not be attempted with any
cementitious grout if the resulting consistency is outside the
manufacturer's recommended range for the existing clear
ances and flow lengths using the method proposed to install
the grout. Once mixed to the right consistency, no additional
water shall be added.
3.2.3 Temperature ranges-Adjust the ambient temperature, grout temperature at placement, and temperature of
foundation and baseplate within the temperature range
recommended by the manufacturer.
3.2.4 Gravity flow placements-All placements shall be made from one side and shall begin at one corner of the plate
or skid and continue at that point until the grout rises above
the bottom of the plate on the opposite side of the plate or
skid. Move the placement point or portable headbox slowly
along the plate from one end to the other or to the next
expansion joint section. The placement point shall not be
moved until the face of grout moves along the length of the
plate on the opposite side. The headbox shall not be allowed
to become empty once the grout rises to the bottom of the
headbox. Grout shall not be placed at various locations
along one side. Grout shall not be poured toward the center
from opposite ends or sides. When using expansion joints,
pour grout into the adjoining expansion joint area once the
previous area is at least 50 percent full. Follow the manu
facturer's recommendations for thick placements to control
heat generation and shrinkage.
3.2.5 Pumped placement-Pumping shall begin at the grout inlet nearest one end of the plate. Grout shall be
pumped into that inlet until it flows up into an adjacent
inlet and flows from the entire plate perimeter adjacent to
the inlet. The pump line shall then be moved to the adjacent
inlet and pumping continued. The pump line shall be moved
to successive inlets until grouting is complete. Grout shall
not be pumped into more than one inlet simultaneously or
before grout flow has reached an adjacent inlet. When a hose
or lance is to be used to pump grout under the plate, the hose
or lance shall be inserted under the plate to the point farthest
from the point of insertion. The hose or lance shall be with
drawn as grout is pumped under the plate but the hose or
lance outlet shall remain embedded in the grout. Dispos
able hoses may be left in place, provided that they are full
of grout.
3.2.6 No forms, headbox, or grout (except spillage) shall be removed until the grout has stiffened sufficiently to ensure
that the grout does not sag below plate level.
3.2.7 Surface finishes-Finish surface in accordance with manufacturer's specification, or as specified in Contract
Documents. If a troweled or broomed finished is specified,
finish surface while grout is still tacky.
3.2.8 Headboxes-Remove any grout headboxes after grout has set sufficiently. Do not plug or fill baseplate and
void holes until the grout has set.
3.2.9 After placement, the foundation and machine or equipment base shall be kept at a temperature that is
within the temperature range specified for placing, curing,
and strength development requirements for the grout. The
temperature shall be maintained within this range until the
grout reaches final set. After final set, the grout shall be
protected from cold or hot weather conditions until design
strength is achieved. The grout shall be cured in accordance
with the manufacturer's written instructions. The tempera
ture shall then be adjusted to ambient temperatures over a
period of 48 hours.

3.2.10 Once grout has reached design strength, remove jackscrews and temporary shims.
3.2.11 Fill any expansion joints with accepted material. 3.2.12 Unless otherwise specified, coat top of foundation
and grout with accepted coating material.
3.2.13 Tension anchor bolts as specified in Contract Documents.
3.3-Testing and inspection 3.3.1 Sample collection-Samples shall be taken every
day and when any of the component batch numbers change
during cementitious grout installation. Test samples for prop
erties critical to the installation such as flow, wet density,
bleed, and strength, using documented test methods appro
priate to the type of grout, as cited in the Contract Docu
ments and grout manufacturer's instructions.
3.3.2 Inspect baseplates for movement beyond the specified tolerances. If movement has occurred, notify Architect/
Engineer to determine resolution.
3.3.3 Inspect the grout for softness. Inspect the grout for voids by tapping on the plate and listening for hollow sounds.
3.4-Repair
3.4.1 If voids are detected, fill voids according to manufacturer's recommendations. Recheck for voids. Repeat the
void filling and checking as necessary to ensure no voids are
present.
3.5-Cieaning
3.5.1 Immediately after grouting is completed, all tools and mixing equipment shall be cleaned using water or an
approved solvent.
3.5.2 All unused mixed grout materials and clean-up residue shall be disposed of in accordance with Contract
Documents.
