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.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>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. (<\/strong><a href=\"https:\/\/www.fairmateprashita.com\/blog\/tag\/flowgrout\/\"><strong>Fairmate Prashita<\/strong><\/a><strong>)<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Is Non-Shrink Grout?<\/strong><\/h2>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>The term \u201cnon-shrink\u201d 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.<\/strong><\/p>\n\n\n\n<p><strong>A good non-shrink grout should offer:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High compressive strength<\/strong><\/li>\n\n\n\n<li><strong>Free-flowing or pourable consistency<\/strong><\/li>\n\n\n\n<li><strong>Good bond with concrete and steel<\/strong><\/li>\n\n\n\n<li><strong>Volume stability<\/strong><\/li>\n\n\n\n<li><strong>Low permeability<\/strong><\/li>\n\n\n\n<li><strong>Resistance to vibration and dynamic loads<\/strong><\/li>\n\n\n\n<li><strong>Easy placement in confined spaces<\/strong><\/li>\n\n\n\n<li><strong>Durability under site conditions<\/strong><\/li>\n<\/ul>\n\n\n\n<p><strong>Fairmate Prashita\u2019s 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\/cm\u00b2 compressive strength at 28 days.

Ordinary mortar may look strong after hardening, but it can shrink, crack, bleed, segregate and fail to fill hidden voids properly.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Types of Non-Shrink Grout<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Cementitious Non-Shrink Grout<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>FLOWGROUT 40 and FLOWGROUT 60 are suitable product mentions for cementitious non-shrink grouting applications.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. High-Strength Grout<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>FLOWGROUT 60 is a relevant product here because it is described as ultra-high-strength, free-flowing and non-shrink.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Epoxy Grout<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>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. (<\/strong><a href=\"https:\/\/www.fairmateprashita.com\/blog\/tag\/flowgrout\/\"><strong>Fairmate Prashita<\/strong><\/a><strong>)<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Anchoring Grout<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>Fairmate Prashita\u2019s engineering grout product list includes ANCHORGROUT and ANCHORFIX RESIN CAPSULE, making them suitable mentions for anchoring and fixing applications. (<\/strong><a href=\"https:\/\/www.fairmateprashita.com\/blog\/tag\/flowgrout\/\"><strong>Fairmate Prashita<\/strong><\/a><strong>)<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Where Is Non-Shrink Grout Used?<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Base Plate Grouting<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Machine Foundation Grouting<\/strong><\/h3>\n\n\n\n<p><strong>Machinery such as pumps, compressors, generators, turbines, presses and industrial equipment requires stable foundations. These machines often create vibration and dynamic loads.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Anchor Bolt and Bolt Pocket Grouting<\/strong><\/h3>\n\n\n\n<p><strong>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. (<\/strong><a href=\"https:\/\/www.fairmateprashita.com\/blog\/tag\/flowgrout\/\"><strong>Fairmate Prashita<\/strong><\/a><strong>)<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Crane Rail and Stanchion Base Grouting<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Precast Concrete Connections<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>6. Bridge Bearings and Infrastructure Work<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>7. Rebar Anchoring and Structural Fixing<\/strong><\/h3>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>8. Injection Grouting<\/strong><\/h3>\n\n\n\n<p><strong>Some engineering grout systems are also used for filling voids, cracks and cavities through injection methods. Fairmate Prashita\u2019s engineering grout category includes injection grouting range products under FLOWGROUT. (<\/strong><a href=\"https:\/\/www.fairmateprashita.com\/Solutions\/construction_chemicals\/engineering-grouts\"><strong>Fairmate Prashita<\/strong><\/a><strong>)<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Benefits of Non-Shrink Grout<\/strong><\/h2>\n\n\n\n<p><strong>Non-shrink grout provides several important benefits for construction and industrial projects:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>It fills gaps and voids effectively<\/strong><\/li>\n\n\n\n<li><strong>It provides high compressive strength<\/strong><\/li>\n\n\n\n<li><strong>It ensures uniform load transfer<\/strong><\/li>\n\n\n\n<li><strong>It reduces risk of cracking and settlement<\/strong><\/li>\n\n\n\n<li><strong>It supports machinery alignment<\/strong><\/li>\n\n\n\n<li><strong>It performs better than ordinary mortar<\/strong><\/li>\n\n\n\n<li><strong>It helps resist vibration and dynamic loads<\/strong><\/li>\n\n\n\n<li><strong>It bonds well with concrete and steel<\/strong><\/li>\n\n\n\n<li><strong>It supports long-term durability<\/strong><\/li>\n\n\n\n<li><strong>It improves reliability of structural connections<\/strong><\/li>\n<\/ul>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Correct Application Method Matters<\/strong><\/h2>\n\n\n\n<p><strong>Even the best non-shrink grout can fail if applied incorrectly. Site teams must follow correct surface preparation, mixing, placement and curing methods.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>For epoxy grout, surface preparation, mixing ratio, pot life, temperature and chemical exposure conditions must be carefully followed.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How to Select the Right Non-Shrink Grout<\/strong><\/h2>\n\n\n\n<p><strong>The right grout depends on:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Gap size<\/strong><\/li>\n\n\n\n<li><strong>Load condition<\/strong><\/li>\n\n\n\n<li><strong>Dynamic or static loading<\/strong><\/li>\n\n\n\n<li><strong>Required compressive strength<\/strong><\/li>\n\n\n\n<li><strong>Chemical exposure<\/strong><\/li>\n\n\n\n<li><strong>Temperature condition<\/strong><\/li>\n\n\n\n<li><strong>Equipment type<\/strong><\/li>\n\n\n\n<li><strong>Foundation design<\/strong><\/li>\n\n\n\n<li><strong>Application thickness<\/strong><\/li>\n\n\n\n<li><strong>Site accessibility<\/strong><\/li>\n\n\n\n<li><strong>Required setting time<\/strong><\/li>\n\n\n\n<li><strong>Cementitious or epoxy requirement<\/strong><\/li>\n<\/ul>\n\n\n\n<p><strong>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.<\/strong><\/p>\n\n\n\n<p><strong>This is why technical consultation is important before final product selection.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p><strong>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.
