Engineering Grout for Machinery Foundations and Base Plates

Machinery and industrial equipment are commonly installed over reinforced-concrete foundations. Although the machine rests on a steel base plate, the base plate does not usually make direct and complete contact with the concrete foundation.

A designed gap is left between the base plate and the foundation so the equipment can be positioned, aligned and levelled. This gap must then be filled with a suitable engineering grout.

The grout is not merely a material used to hide or fill the visible space. It forms an important load-transfer interface between the machine and the concrete foundation.

Incorrect grout selection or application can result in voids, loss of contact, poor support, alignment concerns, vibration-related problems and premature maintenance.

This guide explains how engineers, industrial contractors and plant-maintenance teams should select engineering grout for machinery foundations, base plates and anchoring applications.

1. Understand the Function of Engineering Grout

Engineering grout performs several important functions beneath machinery and equipment.

It helps:

Fill the designed gap beneath the base plate
Establish contact between steel and concrete
Transfer operational loads to the foundation
Fill confined areas around anchor bolts
Support alignment and levelling
Reduce the risk of unsupported sections
Provide a durable interface beneath the equipment

The grout should work as part of the complete machine-foundation system.

Foundation design, anchor arrangement, base-plate stiffness, equipment loading and installation quality all influence performance.

2. Why Ordinary Mortar Is Not Suitable

Ordinary site-made cement and sand mortar may appear economical, but it is generally not designed for precision grouting.

Potential limitations include:

Inadequate flow under wide base plates
Difficulty filling narrow or congested gaps
Shrinkage after placement
Variable water addition
Inconsistent aggregate grading
Inconsistent strength
Bleeding and segregation
Hidden voids
Poor contact around anchor locations

A mortar that looks satisfactory at the visible edges may still leave unfilled areas beneath the centre of the plate.

Purpose-designed engineering grout is manufactured to provide controlled flow, strength development and dimensional stability when mixed and placed according to the Technical Data Sheet.

3. Determine Whether the Equipment Is Static or Dynamic

The operating condition of the equipment is an important selection factor.

Static equipment

Examples may include:

Tanks
Columns
Storage vessels
Structural supports
Light equipment frames
Certain processing units

These installations primarily transfer static loads, although thermal and operational movement may still occur.

Dynamic equipment

Examples may include:

Compressors
Turbines
Pumps
Generators
Crushers
Mills
Heavy rotating machinery
Reciprocating equipment

Dynamic equipment may create vibration, impact, cyclic loading and repeated operational stresses.

Grout for dynamic machinery should be selected based on the machine manufacturer’s requirements, foundation design and expected operating conditions.

4. Measure the Grout Gap Correctly

Grout gap is one of the most important selection criteria.

The selected product should be suitable for the:

Minimum gap
Maximum gap
Length and width of the base plate
Volume of grout
Placement distance
Congestion around anchor bolts
Accessibility of the pouring area

A product developed for a relatively narrow gap may not be suitable for a deep foundation pocket without approved aggregate extension or a different grout grade.

For example, Fairmate Prashita’s FLOWGROUT 60 is intended for suitable precision-grouting applications within its specified gap range. For deeper sections or larger volumes, the latest TDS and technical recommendation should be followed.

Never assume that one grout grade can be used at any thickness.

5. Review Strength Requirements

Engineering grout may need to achieve:

Early strength for equipment installation
Strength before bolt tightening
Strength before machine commissioning
Long-term compressive strength
Suitable load-bearing capability

However, the highest available compressive strength is not automatically the correct choice.

The selected grout must also provide:

Suitable flow
Non-shrink behaviour
Good dimensional stability
Correct application thickness
Compatible stiffness
Reliable placement
Appropriate durability

A high-strength grout that cannot be placed properly under the base plate will not provide the required support.

6. Select the Correct Flow Consistency

Engineering grout may be mixed to different consistencies depending on the product and application.

Typical categories include:

Plastic
Flowable
Highly flowable

A flowable or highly flowable grout is commonly selected where the material needs to travel beneath a plate and around anchor locations.

Water should never be increased beyond the recommended range simply to improve flow. Excess water may contribute to:

Lower strength
Increased porosity
Segregation
Bleeding
Greater dimensional change
Reduced durability

The required flow should be achieved using the correct product and approved water ratio.

7. Consider Cementitious or Resin Grout

Engineering grouts may broadly be divided into cementitious and resin-based systems.

Cementitious non-shrink grout

Cementitious grout is widely used for:

Machinery base plates
Equipment foundations
Anchor bolts
Structural supports
Crane rails
General industrial grouting

Advantages may include:

Free-flowing placement
Non-shrink performance
High compressive strength
Compatibility with concrete foundations
Practical application for many industrial installations

Resin or epoxy grout

Resin-based grout may be considered where there are demanding requirements involving:

Severe dynamic loading
High vibration
Chemical exposure
Oil contamination risk
Rapid commissioning
Exceptional mechanical performance
Special machine-manufacturer requirements

The correct system should be selected with reference to operating conditions and engineering specifications.

8. Prepare the Concrete Foundation

Correct foundation preparation is essential for grout bonding and load transfer.

The concrete surface should be:

Structurally sound
Free from laitance
Free from loose material
Free from dust and debris
Free from oil and grease
Properly roughened where specified
Cleaned before placement

For cementitious grout, the concrete may need to be saturated with clean water before application, while ensuring there is no standing water when grout placement begins.

The latest product instructions should always be followed.

9. Prepare the Base Plate and Anchor Locations

The underside of the base plate should be clean and free from:

Oil
Grease
Loose rust
Paint contamination
Dirt
Debris

Anchor-bolt pockets should be inspected and cleaned before grouting.

The installation team should also confirm:

Correct machine alignment
Correct levelling
Stable shims or levelling devices
Proper anchor-bolt positioning
Adequate grout access
Suitable venting arrangements

Grout cannot compensate for incorrectly aligned machinery or an inadequately designed foundation.

10. Use Strong and Leakproof Formwork

Engineering grout is often highly flowable. Weak or poorly sealed formwork can result in leakage, loss of grout head and incomplete placement.

Formwork should be:

Strong enough to resist grout pressure
Sealed at joints
Securely fixed
Extended above the base plate where a grout head is required
Designed to permit continuous placement
Treated with a suitable release material where required

Foam, sealant or mortar may be used to seal formwork joints depending on the application.

A trial check with water may be useful before grout placement, provided the area is subsequently prepared according to product instructions.

11. Mix the Grout Correctly

Engineering grout should be mixed using suitable mechanical equipment.

A typical process involves:

Measuring the required clean water
Adding most of the water to the mixing container
Adding the grout powder gradually
Mixing until a uniform consistency is achieved
Adding the remaining permitted water if required
Mixing for the specified duration
Placing within the stated working time

Avoid:

Hand mixing large batches
Estimating the water quantity
Adding additional water after the grout begins stiffening
Mixing more material than can be placed in time
Using contaminated containers or tools

Consistent batch preparation is important when grouting large machinery bases.

12. Pour Continuously from One Side

Grout should generally be placed continuously from one side of the base plate.

This helps push air ahead of the grout and reduces the likelihood of trapping voids beneath the plate.

Good placement practice includes:

Maintaining a continuous grout flow
Keeping an adequate grout head
Avoiding placement from several opposing sides
Providing controlled venting
Using suitable chains or straps only where permitted
Ensuring the pour is not interrupted
Preparing sufficient material and labour before starting

Random pouring from multiple sides may trap air in the centre of the base plate.

13. Plan the Grouting Operation Before Mixing

Before beginning, the site team should confirm:

Total grout volume
Additional allowance for wastage
Number of bags required
Water quantity
Mixing capacity
Number of mixers
Manpower
Placement route
Formwork condition
Backup equipment
Ambient temperature
Expected working time

Large machinery foundations should not be treated as improvised repair activities.

A documented method statement and coordinated placement plan can reduce interruptions and inconsistency.

14. Consider Temperature and Site Conditions

Temperature affects grout behaviour.

High temperatures may:

Reduce working time
Increase water demand
Cause rapid moisture loss
Increase placement difficulty

Low temperatures may:

Slow strength development
Extend setting time
Delay commissioning

Water, grout bags, equipment and the foundation may need to be protected from extreme temperatures.

Product-specific guidance should be followed for hot- or cold-weather placement.

15. Complete Curing and Finishing

After placement, exposed grout shoulders and surfaces should be finished and cured according to the Technical Data Sheet.

Poor curing may contribute to:

Surface cracking
Rapid moisture loss
Weak exposed edges
Reduced durability

The equipment should not be commissioned until the required grout strength has been achieved.

Final tightening, loading and commissioning should follow the machine supplier’s and engineer’s requirements.

16. Select the FLOWGROUT Grade for the Application

Fairmate Prashita’s FLOWGROUT range provides engineering grout solutions for suitable applications such as:

Machinery foundations
Steel base plates
Anchor bolts
Equipment foundations
Crane rails
Structural bearing areas
Industrial installations

FLOWGROUT 60 is an ultra-high-strength, free-flowing and non-shrink cementitious grout for suitable precision-grouting applications within its stated parameters.

Final selection should consider:

Machine load
Operating condition
Grout gap
Required strength
Placement method
Exposure
Foundation condition
Commissioning schedule

The latest Technical Data Sheet and project-specific recommendation should be reviewed before use.

Engineering Grout Selection Checklist

Before selecting engineering grout, confirm:

Is the equipment static or dynamic?
What is the machine operating load?
What is the minimum and maximum grout gap?
What are the base-plate dimensions?
What early strength is required?
When will the machine be commissioned?
Is the grout area exposed to oil or chemicals?
Can grout be poured continuously from one side?
Is the foundation sound and prepared?
Is the formwork leakproof?
Has sufficient grout and mixing capacity been arranged?
Has the latest TDS been reviewed?

Conclusion

Stable machinery support begins below the base plate.

Engineering grout should be selected as part of the complete equipment-foundation system—not as an ordinary gap-filling mortar.

Correct selection depends on:

Equipment loading
Static or dynamic operation
Grout-gap depth
Required flow
Strength development
Foundation preparation
Placement access
Exposure conditions
Commissioning requirements

Purpose-designed, free-flowing and non-shrink engineering grout helps achieve reliable contact beneath machinery base plates when installed correctly.

What Is Non-Shrink Grout and Where Is It Used?

In construction, even a small void below a machine base plate, column base, anchor bolt or structural connection can create major performance problems. These voids can lead to poor load transfer, vibration, misalignment, cracking, settlement and long-term maintenance issues. This is why ordinary cement mortar is not suitable for precision grouting applications.

Non-shrink grout is a specially designed construction chemical used to fill gaps, cavities and spaces where strong, stable and reliable load transfer is required. Unlike ordinary mortar, non-shrink grout is engineered to maintain volume stability after placement. It flows into restricted spaces, fills voids properly and develops high strength without excessive shrinkage.

For industrial, commercial and infrastructure projects, non-shrink grout is widely used below base plates, machinery foundations, stanchion bases, precast elements, bridge bearings, anchor bolts, crane rails and structural connections. It plays a critical role in ensuring that loads are transferred evenly from steel or equipment to the concrete foundation.

Fairmate Prashita offers advanced engineering grout solutions under the FLOWGROUT range. The official engineering grout page describes FLOWGROUT as a wide range of cementitious, epoxy and polyurethane-based grouts with non-shrink, free-flowing and high-strength properties. These are used for base plate grouting, injection grouting and anchoring of rebars. (Fairmate Prashita).

What Is Non-Shrink Grout?

Non-shrink grout is a pre-packed, high-strength grouting material that is mixed with a controlled amount of water or resin component depending on the product type. It is designed to flow into gaps and cavities without segregation, bleeding or excessive shrinkage.

The term “non-shrink” does not simply mean that the material never changes volume. It means the grout is formulated to compensate for normal cementitious shrinkage and maintain proper contact with the surfaces it supports. This is important below base plates and machines because even minor gaps can reduce stability and affect load distribution.

A good non-shrink grout should offer:

High compressive strength
Free-flowing or pourable consistency
Good bond with concrete and steel
Volume stability
Low permeability
Resistance to vibration and dynamic loads
Easy placement in confined spaces
Durability under site conditions

Fairmate Prashita’s FLOWGROUT 60 is described as an ultra-high-strength, free-flowing, non-shrink cementitious grout. It is non-metallic, chloride-free and designed for general-purpose grouting under dynamic loads. The product page states that it flows under base plates and bolt pockets and attains 650 kg/cm² compressive strength at 28 days. (Fairmate Prashita)

Why Ordinary Mortar Is Not Enough

Many site failures happen because normal cement-sand mortar is used for base plate or machinery grouting. Ordinary mortar may look strong after hardening, but it can shrink, crack, bleed, segregate and fail to fill hidden voids properly.

In high-load or vibration-prone areas, ordinary mortar can lose contact with the base plate. This creates uneven load transfer. Over time, vibration can loosen anchors, damage equipment alignment and create cracks in the foundation.

Non-shrink grout is designed specifically to solve this problem. It fills gaps properly, remains stable and supports stronger contact between the foundation and the supported element. This helps improve safety, performance and durability.

Types of Non-Shrink Grout

1. Cementitious Non-Shrink Grout

This is the most commonly used type for general construction and industrial grouting. It is supplied as a ready-to-use powder and requires only measured water at site. It is suitable for base plates, columns, stanchion bases, equipment foundations and precast connections.

FLOWGROUT 40 and FLOWGROUT 60 are suitable product mentions for cementitious non-shrink grouting applications.

2. High-Strength Grout

High-strength grout is used where higher compressive strength, durability and load-bearing capacity are required. It is suitable for heavy machinery, industrial units, infrastructure projects and structural grouting.

FLOWGROUT 60 is a relevant product here because it is described as ultra-high-strength, free-flowing and non-shrink.

3. Epoxy Grout

Epoxy grout is used where extreme chemical resistance, vibration resistance, heavy loads or very high performance is required. It is commonly used for heavy-duty machinery, turbines, compressors, pumps, industrial equipment and precision alignment.

Relevant Fairmate Prashita product mentions include FLOWGROUT EP and FLOWGROUT EP(L) from the FLOWGROUT engineering grout range. The FLOWGROUT product list on the website includes FLOWGROUT EP, FLOWGROUT EP(H), FLOWGROUT EP(L), FLOWGROUT EPLV and related epoxy grout variants. (Fairmate Prashita)

4. Anchoring Grout

Anchoring grout is used for fixing anchor bolts, rebars, dowels and structural steel elements into concrete. It helps create a strong connection between steel and concrete.

Fairmate Prashita’s engineering grout product list includes ANCHORGROUT and ANCHORFIX RESIN CAPSULE, making them suitable mentions for anchoring and fixing applications. (Fairmate Prashita)

Where Is Non-Shrink Grout Used?

1. Base Plate Grouting

This is one of the most common uses of non-shrink grout. Steel columns, machines and equipment are mounted on base plates. The grout fills the gap between the concrete foundation and the base plate to provide uniform load transfer.

If this gap is not filled correctly, the base plate may not sit properly, causing uneven pressure, cracks or movement. Non-shrink grout ensures strong contact and stable performance.

2. Machine Foundation Grouting

Machinery such as pumps, compressors, generators, turbines, presses and industrial equipment requires stable foundations. These machines often create vibration and dynamic loads.

Non-shrink grout helps maintain alignment and transfers load safely to the foundation. For dynamic load conditions, high-strength cementitious grout or epoxy grout may be selected depending on project requirements.

3. Anchor Bolt and Bolt Pocket Grouting

Anchor bolts need proper embedment and surrounding support. Non-shrink grout is used to fill bolt pockets and secure the bolts in position. FLOWGROUT 60 is specifically described as freely flowing under base plates and bolt pockets. (Fairmate Prashita)

4. Crane Rail and Stanchion Base Grouting

Industrial buildings, warehouses, factories and plants often use crane rails and stanchion bases. These areas are exposed to heavy loads and repeated movement. Non-shrink grout helps support load-bearing steel elements and reduces the risk of settlement or cracking.

5. Precast Concrete Connections

Precast construction requires precise connection between elements. Non-shrink grout is used for joints, sleeves, pockets and connection gaps to ensure proper bonding and load transfer.

6. Bridge Bearings and Infrastructure Work

Bridges, flyovers, metro structures and infrastructure projects require reliable grouting below bearings and structural plates. Non-shrink grout helps achieve uniform support and long-term durability in these critical areas.

7. Rebar Anchoring and Structural Fixing

When rebars, dowels or anchors are fixed into existing concrete, anchoring grout or resin capsule systems help create a strong bond. This is important in strengthening, retrofitting, repair and structural extension works.

8. Injection Grouting

Some engineering grout systems are also used for filling voids, cracks and cavities through injection methods. Fairmate Prashita’s engineering grout category includes injection grouting range products under FLOWGROUT. (Fairmate Prashita)

Benefits of Non-Shrink Grout

Non-shrink grout provides several important benefits for construction and industrial projects:

It fills gaps and voids effectively
It provides high compressive strength
It ensures uniform load transfer
It reduces risk of cracking and settlement
It supports machinery alignment
It performs better than ordinary mortar
It helps resist vibration and dynamic loads
It bonds well with concrete and steel
It supports long-term durability
It improves reliability of structural connections

For project owners and engineers, the biggest benefit is performance assurance. Non-shrink grout helps reduce the risk of hidden gaps and weak contact zones that may affect the structure or equipment later.

Correct Application Method Matters

Even the best non-shrink grout can fail if applied incorrectly. Site teams must follow correct surface preparation, mixing, placement and curing methods.

Before grouting, the concrete surface should be clean, sound and free from oil, dust, laitance and loose particles. The area should be properly shuttered to avoid leakage. Water should be measured accurately as per product requirement. Over-watering should be avoided because it can reduce strength and cause segregation.

Mechanical mixing is preferred for uniform consistency. The grout should be poured continuously from one side to avoid air entrapment. After placement, curing and protection should be done as recommended.

For epoxy grout, surface preparation, mixing ratio, pot life, temperature and chemical exposure conditions must be carefully followed.

How to Select the Right Non-Shrink Grout

The right grout depends on:

Gap size
Load condition
Dynamic or static loading
Required compressive strength
Chemical exposure
Temperature condition
Equipment type
Foundation design
Application thickness
Site accessibility
Required setting time
Cementitious or epoxy requirement

For general base plate grouting, a cementitious non-shrink grout may be sufficient. For heavy industrial equipment, epoxy grout or ultra-high-strength grout may be required. For large-section grouting, aggregate-filled or special-grade grout may be preferred. For anchoring work, anchoring grout or resin capsule systems may be selected.

This is why technical consultation is important before final product selection.

Conclusion

Non-shrink grout is an essential construction chemical for precision grouting, base plate support, machine foundations, anchor bolts, bridge bearings, precast connections and industrial structural applications. It provides high strength, free flow, volume stability and reliable load transfer where ordinary mortar cannot perform.

FLOWGROUT 60

ULTRA HIGH STRENGTH, FREE FLOWING, NON-SHRINK CEMENTITIOUS GROUT

FLOWGROUT 60 is based on specially processed cement containing fillers and additives. FLOWGROUT 60 is supplied as ready-to-use grout requiring the addition of a precise quantity of water at the site (3.750 to 4 Litre/25 Kg Grout). FLOWGROUT 60 is suitable for gap widths of between 10mm – 50mm. For thickness over 50mm. (say 75-100), cleaned washed 10mm aggregates can be incorporated at the rate of 20% of the quantity of grout used. This reduces the heat of hydration.
Expansion: Controlled expansion occurs in the unset material to ensure that the grout, when cured will continue to occupy its original volume within the confines of the voids in which it was placed. For thicker sections, it is necessary to fill out the grout with well-graded silt free aggregate to minimize heat buildup.

SALIENT FEATURES
• Prepacked, factory controlled consistent material needing only addition of water
• Shrinkage offset by expansion to ensure original volume is retained
• Free flowing, self-leveling grout
• Can withstand temperature up to 200ºC
• Easy placement and filling of underbases of machinery
• Non-metallic, non-toxic and chloride free
• Holds up to industrial machinery vibration & impact
• Extended work time for easy placement
• Excellent adhesion to concrete and steel
• Non staining
• High ultimate strength and durability

APPLICATION PROCEDURE

Surface Preparation:
• All contaminated surfaces must be cleaned thoroughly by chemical or mechanical methods.
• All bolt pockets and under bases must be free from dust, laitance, and of sound substrate. If needed, substrate with water to allow for full absorption for at least 24 hours.
• Just before the grouting is to commence, all water must be removed completely leaving the surface only damp.

Mixing: Mechanical mixing using a grout mixer or concrete mixer is recommended.
• Place 80% of the water required in a concrete mixer (100% water in case of a grout mixer).
• Slowly add the required amount of FLOWGROUT 60 while mixing continuously for 1 minute. Add balance quantity of water (20%) and mix for 3 to 5 minutes. This will provide a smooth even consistency of grout.

Bolt Packets:
• Depending on the size of the bolt pockets, 50- 100% cleaned 10mm sound aggregates by weight of grout consumption may be sealed incorporated to economies on grout and also to keep the heat of hydration low.
Under base Plate:
• Leak proof strong formwork must be provided to withstand operational stresses while grouting and all edges must be sealed with FLOWGROUT 60 troweling consistency to arrest the grout flowing out of formwork.
CURING:
• 3-4 hours after grouting, all exposed areas must be cured with wet hessian cloths (keep wet always) or water ponding wherever possible for minimum 7 days.

FLOWGROUT 60 can be used to Bolt pockets and base plate grouting of all equipment, Crane, stanchion bases and all types of machinery with dynamic load.

FLOWGROUT 40

HIGH STRENGTH, FREE FLOW, NON-SHRINK GROUT

FLOWROUT 40 is a single pack ready use, high-strength, free-flowing and non-shrink grout.
FLOWGROUT 40 is based on specially processed types of cement containing fillers and additives. FLOWGROUT 40 is supply as ready-to-use grout requiring the addition of a precise quantity of water at the site (4.75 Litre/25 Kg grout).
Expansion: Controlled expansion occurs in the unset material to ensure that the grout, when cured will continue occupy its original volume within the confines of the voids in which it was placed. FLOWGROUT 40 is suitable for gap widths between 10mm-50mm. For widths, less than 10mm FLOWGROUT EP resin grout can be used. For thickness above 50mm. (say 75-100), cleaned washed 10mm aggregates can be incorporated at the rate of 50%-100% of the quantity of grout used. Water needs to be precisely measured for good early & final strength.

SALIENT FEATURES
• Material shrinkage is offset by expansion during green condition and later on by maintaining original volume.
• Self-leveling by nature.
• Can withstand temperature up to 200ºC
• Easy placement and filling of under bases of machinery.
• Non-metallic and chloride free.

APPLICATION PROCEDURE

Surface Preparation:
• All contaminations fully removed by chemical or mechanical methods.
• All bolt pockets and under bases must be free from dust, laitance. If needed, substrate must be hacked to provide extra mechanical key.
• The pockets and under bases must be saturated with water to allow for full absorption for at least 24 hours. Just before the grouting is to commence, all water must be removed completely leaving the surface only damp.

Mixing: Mechanical mixing using a grout mixer or concrete mixer is recommended.
• Place 80% of the water required in a concrete mixer (100% water in case of a grout mixer).
• Slowly add the required amount of FLOWGROUT 40 while mixing continuously for 1 minute. Add balance quantity of water (20%) and mix for 3 to 5 minutes. This will provide a smooth even consistency of grout.
Placing:
• The mixed grout poured immediately from one side only to avoid air pockets.
• Grouting must be continuous until the cavity is completely filled to the desired level.
• All exposed areas must be restrained by covering with wooden plates or polythene sheets with sand sprinkled on top of the sheet.
Bolt Packets:
• Depending on the size of the bolt pockets, 50- 100% cleaned 10mm sound aggregates by weight of grout consumption may be sealed incorporated to economise on grout and also to keep the heat of hydration low.
Under base Plate:
• Leak proof strong formwork must be provided to withstand operational stresses while grouting and all edges must be sealed with FLOWGROUT 40 troweling consistency to arrest the grout flowing out of formwork.
Curing:
• Within 8 hours of grouting all grouted areas must be cured with wet hessian cloth or water pounding according to the temperature for a minimum 7 days period.

It can be used in bolt pockets and base plate grouting of all rotary and static equipment, crane, stanchion based and all types of machinery in all types of industrial projects.

FLOWGROUT HES – CEMENTITIOUS, HIGH EARLY STRENGTH, FLOWABLE FAST SETTING GROUT

Benefits
1. High early strength (even at low temperatures).
2. Very good flow characteristic.
3. Fast set times & fast strength gain.
4. Consistency can be adjusted as per requirement.
5. High 28 day strengths.
6. Does not bleed or segregate.
7. Very good impact and thermal resistance.
8. Non corrosive to steel or iron.
9. Excellent bond strength.
10. Pre-packed factory controlled to overcome site batched variations
11. Does not contains any corrosive chemicals

Description
FLOWGROUT HES is a blend of special cement, selected and graded aggregates and Fairmate admixtures, enabling it to achieve high strengths in short time frame.

Recommended Uses
FLOWGROUT HES is useful for wide range of applications where fast strength is required, like:
1. Machine bedplates.
2. Anchoring bolts.
3. Bridge bearing pads.
4. Pre-cast concrete sections.
5. Cavities, gaps and recesses.

Application Instructions
Surface Preparation: All surfaces must be clean, sound and free from dust, ice, oils, grease or other surface contaminants such as curing membranes and form release agent etc. Bolt holes and fixing pockets should be free of dirt and debris by air blasting. For maximum bond, surfaces should be abraded or roughened, preferably by mechanical means such as needle gun, grit blasting, grinding etc. All prepared surfaces must be saturated with water several hours prior to grouting, ensuring it is free of any surface water or puddles.

Temperature control :
Temperature affects setting time and rate of increase for strength. For optimum performance maintain grout, concrete and/or steel substrates within the range of 25-30ºC prior to, during, and for 48 hours after placement of the grout.

Mixing Equipment :
FLOWGROUT HES is must be mechanically mixed using a mechanical grout mixer or a suitable drum mixer. The grout mixer will reduce the chances of the mix becoming lumpy or aerated.

Mixing Method:
1) 4 Liters of clean water per 25 kg bag of grout.
2) Add the powder component to approximately 80% of the total amount water component while mixing.
3) Add the remaining 20% of the water component to the grout at a steady rate while continuing to mix.
4) Mix until the grout appears homogenous (3-5 minutes). Allow to stand so any entrapped air can escape. Do not add more water to increase flow of the grout if a mix has stiffened due to time delays. If the grout is unworkable discard.
