What Is Non‑Shrink Grout?
Non-shrink grout is a cementitious, flowable, two-stage expanding grout with carefully selected aggregates and admixtures. Unlike standard grouts that may shrink as they cure (leading to cavities or poor contact), Non Shrink Grout is engineered to maintain full contact under load by expanding slightly to compensate for any shrinkage.
These characteristics make it ideal for applications where tight bearing, anchorage strength, and long-term stability are essential.
According to Satiate’s product page, non‑shrink grouts can be used in a spectrum from “dry‑pack” to highly flowable mixes — yet still retain their non‑shrink and strength properties.
Sample Project Scenario
Imagine you are installing a heavy machine frame on a concrete foundation. The base plate must sit perfectly flat, with no gaps underneath, to avoid stress concentration. Using Sika non‑shrink grout ensures that, during curing, the grout slightly expands to fill any micro-gaps — producing full contact across the plate underside. This ensures uniform load transfer, avoids local stress, and helps in long-term service life.
In a rail or crane bed application, vibration is constantly present. Here, use a high-quality pitch non‑shrink grout (as suggested by Satiate) to resist micro-movement, erosion, and fatigue.
Applications of Non-Shrink Grout
Non-shrink grout is widely used in construction, infrastructure, and industrial projects where precision, strength, and dimensional stability are essential. Due to its non-shrinking and high-strength properties, it ensures full contact between structural elements and helps in long-term durability of installations.
Below are the most common and critical applications of non-shrink grout:
1. Base Plate Grouting
Non-shrink grout is often used to fill the gap between steel base plates and concrete foundations. This ensures complete bearing contact, allowing uniform load transfer from structures or equipment to the foundation. It's vital for supporting columns, beams, and heavy structural frames.
2. Machine and Equipment Foundations
In industrial settings, machines like turbines, compressors, generators, and motors require solid, vibration-resistant foundations. Non Shrink Grout is poured beneath machine bases to:
It plays a crucial role in resisting dynamic loads and maintaining machine accuracy.
3. Anchor Bolts and Dowels
Non-shrink grout is ideal for embedding and securing anchor bolts, dowels, tie rods, and reinforcing bars. It provides:
High bonding strength
Resistance to pull-out
Durability under cyclic loading
This application is essential in bridges, highways, railings, and industrial structures.
4. Precast Concrete Connections
When joining precast elements (such as columns, beams, or panels), non-shrink grout ensures a tight, gap-free fit between components. This enhances structural integrity and ensures load distribution without shrinkage cracks.
5. Crane Rails and Tracks
Non-shrink grout is used beneath crane rails and heavy tracks to maintain proper alignment and prevent long-term settlement. Since these applications often face heavy impact and vibrations, the grout must:
Why Use a Non‑Shrink Grout?
1. Volume Stability & Expansion
Unlike ordinary cement grouts, non‑shrink grout is engineered to expand slightly (within controlled limits), thereby offsetting the natural shrinkage that occurs during curing. This ensures that the grout remains in contact with surfaces and maintains preload, rather than pulling away or creating gaps.
2. High Load Capacity
Non Shrink Grout achieve high compressive strength early and over time, making them ideal for supporting heavy loads, base plates, structural supports, and anchor bolts.
3. Good Adhesion & Bonding
These grouts bond well with the surrounding concrete or steel, ensuring load transfer and structural integrity.
4. Versatility in Workability
Depending on the formulation, non‑shrink grouts can be “dry pack” (thicker consistency) to highly flowable mixes, giving flexibility for various filling or anchoring requirements.
5. Resistance to Vibration, Chemical Attack, and Harsh Conditions
High‑quality non‑shrink grouts are designed for aggressive environments, dynamic loading, vibration, and chemical exposure. This makes them suitable for industrial installations, bridges, cranes, conveyors, and heavy machinery.
Non‑shrink grout is a critical material in structural and industrial grouting applications where precision, stability, and durability are nonnegotiable. Its ability to maintain or slightly expand in volume during curing makes it superior to conventional grouts in high‑performance installations.

FAQs — Frequently Asked Questions
1. What is the difference between normal cement grout and non‑shrink grout?
Ans. Normal cement grout may shrink as it cures, potentially leaving voids, reducing bearing contact, and lowering performance. Non‑shrink grout, by contrast, is engineered to expand minimally to compensate for shrinkage and maintain full contact under load.
2. When should I use non‑shrink grout instead of epoxy grout?
Ans. Non‑shrink cementitious grouts are excellent for heavy loads, structural anchoring, and larger fill volumes. Epoxy grouts may be used for chemical resistance or in thin sections, but they may be more costly and have limitations in large-scale grouting. Choose based on load, exposure, environmental and cost parameters.
3. Can non‑shrink grout flow into tight gaps?
Ans. One of its strengths is versatility in consistency. It can range from relatively stiff (dry pack) to highly flowable mixes while still maintaining Non Shrink Grout behavior — as Satiate’s product page notes.
4. What temperature conditions are ideal for placing non‑shrink grout?
Ans. Typically, a substrate surface temperature between is recommended (per Satiate). Avoid extremes or rapid temperature shifts that can affect curing.
5. How long does non‑shrink grout take to develop strength?
Ans Curing time depends on mix design, ambient conditions, and thickness. Most grouts reach significant strength within but full rated strength might take. Always refer to manufacturer data for precise schedules.
6. Is non‑shrink grout resistant to vibration and dynamic loads?
Ans: quality non‑shrink grouts (especially pitch-based or high-performance varieties) are formulated to resist micro-movement, erosion and fatigue — ideal for machinery bases, crane rails, etc. Satiate specifically mentions availability of grouts for harsh, vibration-prone environments.
