+
+# Scope {toc}
+
+## This standard governs the materials, performance, preparation, placement, and curing of non-shrink grout used to transfer structural load from steel base plates, bearing plates, and equipment bases into concrete substrates.
+
+### Non-shrink grout fills the clearance between a leveled base plate and its concrete bearing surface so that the full plate area bears uniformly and load transfers without voids, settlement, or loss of contact. {note}
+
+### The defining property is dimensional stability: it must maintain bearing contact under sustained compressive load through the life of the connection. {note}
+
+### The grout shall not exhibit net shrinkage that would break bearing contact between the plate and the substrate.
+
+### Any expansion in the grout shall be controlled so that it does not crack the grout shoulder or lift the base plate off its leveling supports.
+
+### This standard covers both cementitious (hydraulic cement-based) and two-component epoxy grout, with selection between the two driven by load magnitude, chemical and thermal exposure, and dynamic service conditions. {note}
+
+## This standard applies to cast-in-place and precast concrete substrates that have reached their specified strength prior to grouting.
+
+### Typical applications include structural steel column base plates, equipment and machinery foundations, crane rail sole plates, precast panel bearing seats, bridge bearing assemblies, and anchor bolt leveling pockets. {note}
+
+### This standard does not cover the concrete pad, footing, or foundation that receives the grout, nor the design of the steel connection above the base plate. {note}
+
+### The concrete substrate that receives the grout is specified under [[sync/concrete-pads]] or [[sync/cast-in-place-concrete]]; anchor bolt embedment into new footings is specified under [[sync/shallow-foundations]]. {note}
+
+### Base plate sizing, anchor rod design, and connection detailing above the plate are specified under [[sync/structural-steel-connections]] and [[sync/miscellaneous-metals]]; this standard begins at the underside of the plate. {note}
+
+### Masonry mortar beds, grout fill in CMU cores, and non-load-bearing tile or decorative grout are outside this standard. {note}
+
+# Referenced Standards {toc}

+
+# Quality Assurance {toc}
+
+## Grout shall be installed by personnel experienced in precision grouting of the specified type and consistency.
+
+### Cementitious and epoxy grout differ substantially in mixing, placement window, and exotherm behavior; crews trained on one are not automatically competent on the other. {note}
+
+## A single manufacturer's grout system shall be used for each application.
+
+## Products from different manufacturers shall not be combined within one placement.
+
+## Each grout type and lot shall be sampled and tested for compressive strength at the frequency specified in the Testing section.
+
+## The Contractor shall not begin grouting until the Engineer of Record has confirmed that the grout compressive strength specified meets or exceeds the bearing strength assumed in the structural design.
+
+### ACI 318-19 Section 26.11 ties the grout bearing capacity to the design assumptions for the base plate connection; a grout weaker than the assumed value undermines the connection regardless of the plate or anchor design. {note}
+
+## Grout consistency, lift depth, and access geometry shall be verified against the manufacturer's data sheet before placement.
+
+### Fluid-grade grout poured into a deep or one-sided pocket may bridge and leave voids; matching consistency to access is a quality control checkpoint, not a field convenience. {note}
+
+# Environmental and Service Conditions {toc}
+
+## The Contractor shall record ambient air temperature and substrate temperature at the time of placement and throughout the initial cure.
+
+## Grout shall be placed and cured within the temperature range specified on the manufacturer's data sheet, and in no case shall placement proceed with a substrate below 40 °F.
+
+### ASTM C1107 grout and typical manufacturer data assume a placement and cure window of roughly 45-90 °F; outside that window, strength gain, set time, and nonshrink behavior all drift from the qualified values. {note}
+
+### Below 45 °F, hydration slows and the grout may not reach its leveling-nut load before being disturbed; above 90 °F, accelerated set shortens the working window and increases the risk of plastic shrinkage. {note}
+
+## Epoxy grout shall not be specified for sustained service temperatures above the manufacturer's heat-deflection limit.
+
+### Two-component epoxy grout softens under prolonged heat (commonly above about 120 °F) and generates significant exotherm in deep pours; matching the product to the service temperature is essential for heavy equipment near hot processes. {note}

+
+# Grout Type and Composition {toc}
+
+## The grout type shall be selected to match the load magnitude, chemical exposure, thermal exposure, and dynamic service of the application.
+
+### Cementitious non-shrink grout is the default for static structural base plates and most equipment; epoxy grout is reserved for heavy dynamic loads, aggressive chemical exposure, or where the highest strength and impact resistance are required. {note}
+
+## Cementitious grout shall be a packaged, dry, hydraulic-cement non-shrink grout complying with ASTM C1107, requiring only the addition of water at the site.
+
+### Field-blended sand-cement mixes are not non-shrink grout; the nonshrink performance is a property of the proprietary packaged product, verified by the manufacturer to ASTM C827 and C157. {note}
+
+## Cementitious grout shall use a nonmetallic (silica or natural mineral) aggregate.
+
+### Metallic, iron-based aggregate grout oxidizes when exposed to moisture, causing rust staining and surface spalling; nonmetallic aggregate is preferred for nearly all modern applications, including all exterior and wet exposures. {note}
+
+## Epoxy grout, where specified, shall be a two-component or three-component thermosetting system qualified by the manufacturer to ASTM C579 for compressive strength and ASTM C413 for absorption.
+
+### There is no single ASTM product standard for two-component epoxy grout equivalent to ASTM C1107; epoxy grout is governed by manufacturer qualification testing to the relevant ASTM test methods. {note}
+
+## Admixtures shall not be added to packaged grout except those expressly permitted by the manufacturer's published data sheet.
+
+### Adding water or unapproved admixtures to improve flow raises the water-cement ratio, lowers strength, and can void the nonshrink performance; consistency is adjusted only by the manufacturer-approved method. {note}

+# Consistency and Grade {toc}
+
+## The grout consistency shall be selected to match the clearance depth under the plate and the access available for placement.
+
+### ASTM C1107 defines Grades A, B, and C by the time period over which the nonshrink requirement applies; in practice these correspond to fluid, flowable, and plastic (dry-pack) consistencies respectively. {note}
+
+### Fluid grout is self-leveling and poured, flowable grout is poured with a slight head and rodded, and plastic grout is rodded or hand-packed into deep or one-sided pockets where a poured grout would bridge. {note}
+
+## Fluid or flowable consistency shall be used for placements with through-access or a head box where the grout can flow fully beneath the plate.
+
+## Plastic (dry-pack) consistency shall be used where access is restricted to one side or where the pocket is too deep for a poured grout to consolidate without voids.
+
+## The selected consistency shall achieve a minimum effective bearing area of 95 percent of the base plate area in contact with cured grout.
+
+### Effective bearing area is the fraction of the plate that actually bears on solid grout; voids and unfilled zones reduce it and concentrate load on the contact points, which is the failure this standard exists to prevent. {note}
+
+```datasheet
+label: Consistency / Grade
+type: radio
+options:
+ - "Fluid (Grade A) - self-leveling, poured"

+
+# Compressive Strength {toc}
+
+## Cementitious grout shall meet or exceed the ASTM C1107 minimum compressive strengths for the specified grade, tested to ASTM C109.
+
+### The ASTM C1107 standard-grade minimums are 1,000 psi at 1 day, 2,500 psi at 3 days, 3,500 psi at 7 days, and 5,000 psi at 28 days; higher classes reach 8,000 psi (Grade C) and 10,000 psi or more for precision and crane-rail products. {note}
+
+## The 28-day compressive strength shall equal or exceed the value assumed for the grout in the structural base plate design.
+
+## High-early-strength grout shall be specified where the structure or equipment must be loaded before the standard grout reaches its design strength.
+
+## Epoxy grout, where specified, shall develop the manufacturer's published compressive strength tested to ASTM C579.
+
+### Two-component epoxy grout typically develops 12,000-14,000 psi at 7 days per ASTM C579, well above cementitious grout, which is why it is selected for the heaviest and most impact-prone bases. {note}

+
+# Volume Change (Nonshrink Performance) {toc}
+
+## Cementitious grout shall exhibit zero or positive height change in the plastic state when tested to ASTM C827.
+
+## Cementitious grout shall exhibit no net length reduction in the hardened state when tested to ASTM C157.
+
+### "Nonshrink" does not mean "no volume change"; ASTM C1107 permits controlled expansion in the plastic state to compensate for settlement and bleed, while preventing net shrinkage that would break bearing contact after the plate is in place. {note}
+
+## Grout expansion shall not be so large as to crack the grout shoulder or lift the base plate off its leveling supports.
+
+### Excessive expansion is as harmful as shrinkage: it can crack the exposed grout edge or jack the plate against its anchors; this is why expansion is required to be controlled, not maximized. {note}
+
+# Substrate Preparation {toc}
+
+## The concrete substrate shall have reached a minimum compressive strength of 3,000 psi before grouting unless the structural drawings require a higher value.
+
+### ACI PRC-351.1R guidance is that the substrate be substantially mature before grouting so the bearing concrete does not become the weak link beneath a high-strength grout. {note}
+
+## The bearing surface shall be roughened to remove laitance and expose sound aggregate, achieving an ICRI concrete surface profile of CSP 5 to CSP 7.
+
+### Laitance is the weak surface skin left by bleed water; grout bonded to laitance delaminates under load. Roughening to a CSP 5-7 profile removes it and creates mechanical key for the grout. {note}
+
+## All oil, grease, curing compound, paint, dust, and other bond-breaking contamination shall be removed from the bearing surface and anchor pockets before grouting.
+
+## For cementitious grout, the prepared concrete shall be brought to a saturated surface-dry (SSD) condition immediately before placement, with no free standing water in the pocket.
+
+### A dry substrate draws mixing water out of fresh cementitious grout, causing plastic shrinkage and a weak, dusty interface; SSD means the concrete is saturated but the surface holds no puddles that would dilute the grout. {note}
+
+## For epoxy grout, the prepared concrete shall be clean and dry.
+
+## Epoxy grout shall not be placed on a wet or saturated substrate.
+
+### Epoxy chemistry is the opposite of cementitious: water on the surface interferes with the bond and cure, so epoxy substrates are dried, not pre-soaked. {note}

+
+# Clearance Depth and Lift Limits {toc}
+
+## The clearance between the underside of the base plate and the concrete bearing surface shall be set within the range specified for the selected grout and consistency.
+
+### Clearance is set by leveling nuts, shim packs, or wedges; too little clearance prevents the grout from flowing and consolidating beneath the plate, while too much may demand a higher-strength or epoxy grout. {note}
+
+## Cementitious fluid and flowable grout shall be placed in clearances of not less than 3/4 in.
+
+## Cementitious fluid and flowable grout shall be built up in lifts not exceeding the manufacturer's maximum, typically 3 in. to 4 in. per lift.
+
+## Epoxy grout shall be placed in lifts of not less than 1 in. and not more than 3 in. to limit exotherm.
+
+### Deep epoxy pours generate enough internal heat to crack or discolor the grout and accelerate the cure uncontrollably; limiting lift depth keeps the exotherm manageable. {note}
+
+## Deep pockets exceeding the single-lift maximum shall be filled in successive lifts, each allowed to set per the manufacturer's instructions before the next is placed.

+# Forming {toc}
+
+## Forms shall be liquid-tight and constructed to retain fluid grout at the placement head without leakage.

+### Fluid and flowable grout will find any gap; a leaking form bleeds out paste, lowers the head, and leaves voids at the plate edge. {note}
+
+## A head box or extended form shall be provided on the pour side where a hydraulic head is needed to drive grout fully beneath the plate.
+
+## Wood and other absorptive forms shall be thoroughly wetted (for cementitious grout) or coated with form-release (for epoxy grout) before placement.
+
+### Dry wood forms draw water from fresh cementitious grout, causing plastic shrinkage and voids at the grout-form interface; pre-wetting prevents this. For epoxy, a release coat lets the form strip cleanly without bonding. {note}
+
+## Forms shall provide a chamfer or shoulder at the exposed grout edge to relieve the feather edge and resist chipping.

+# Placement {toc}
+
+## The base plate or equipment base shall be set, plumbed, and leveled on leveling nuts, shims, or wedges, and accepted before any grout is placed.
+
+### Grout is not adjustable after it sets; the plate must be at its final elevation and level, and the leveling stack verified, before grouting begins. Grouting first and adjusting later is not possible. {note}
+
+## Mixing water shall be measured and held strictly within the range published on the manufacturer's data sheet.
+
+### Field addition of water beyond the published range is the single most common cause of low-strength, shrinking grout; the water-cement ratio is a controlled quantity, not a flowability dial. {note}
+
+## Grout shall be placed continuously from one side so that it advances across the pocket and pushes air ahead of it, venting from the far side.
+
+### Placing from one side and letting the grout chase the air out is what produces a void-free bearing surface; pouring from multiple sides at once traps air pockets under the plate. {note}
+
+## Grout shall be worked under the plate by gravity head, strapping, chaining, or rodding as appropriate to the consistency, without adding water to ease placement.
+
+## Plastic and dry-pack grout shall be rodded or hand-packed in restricted-access pockets to ensure full consolidation and contact.

+
+# Curing {toc}
+
+## Cementitious grout shall be wet-cured or cured with a manufacturer-approved curing compound for a minimum of 3 days, and 7 days where practical, at an ambient temperature of 50 °F or above.
+
+### Cementitious grout depends on retained moisture to gain strength; premature drying at the exposed edges causes surface shrinkage cracking and a weak skin even when the core is sound. {note}
+
+## A curing compound shall not be applied to any concrete surface that will receive grout, nor to the grout bearing surface itself.
+
+### A curing compound left on the bearing concrete is a bond breaker; that is why curing compound is excluded from the grouted contact area, even though it is acceptable on the exposed grout shoulder. {note}
+
+## Exposed grout edges shall be protected with wet burlap, insulating blankets, or an approved curing compound immediately after the forms permit.
+
+## Epoxy grout shall be cured per the manufacturer's instructions and shall not require wet curing.
+
+### Epoxy grout cures by chemical reaction rather than hydration, so it is not wet-cured; its cure schedule and minimum temperature are governed entirely by the manufacturer's data sheet. {note}

+# Installation Sequencing and Coordination {toc}
+
+## The grouting operation shall be coordinated with the steel erector and the equipment installer so that base plates are leveled and accepted before grout is ordered.
+
+### Grout has a short working life and is sensitive to substrate and ambient conditions, so it is placed only after the plate is final; coordinating the sequence avoids placing grout against a plate that still needs adjustment. {note}
+
+## Anchor bolt pockets and sleeves shall be cleaned of debris and standing water before the leveling and grouting sequence.
+
+## The grout bearing strength assumed in the structural design shall be coordinated with the structural drawings and confirmed by the Engineer of Record prior to placement.
+
+### AISC 360-22 Commentary J8 and ACI 318-19 Section 26.11 both tie the base plate bearing check to the grout strength; the specified grout must match the design assumption, which is a coordination item between the spec and the structural drawings. {note}
+
+# Delivery, Storage, and Handling {toc}
+
+## Packaged grout shall be delivered in the manufacturer's original, unopened, labeled packaging.
+
+## Grout shall be stored off the ground in a dry, covered location and protected from moisture, freezing, and temperature extremes.
+
+### Cementitious grout that has absorbed moisture in storage partially hydrates and loses strength and flow; epoxy components are temperature-sensitive and must be conditioned to the manufacturer's range before mixing. {note}
+
+## Grout that has exceeded its shelf life, shows signs of moisture damage, or has lumped or hardened in the bag shall not be used.
