Top 5 Non-Shrink Grout Products for Precision Grouting
Introduction
Precision grouting is critical when it comes to base plates, anchor bolts, machinery foundations or structural renovation works where accurate alignment and zero settlement are essential. Non-shrink grout products ensure tight bonding, high compressive strength and minimal shrinkage or expansion after curing — delivering long-term stability and structural integrity. In this article, we present the Top 5 non-shrink grout products that are widely regarded for their precision grouting performance.
Why Precision Grouting Requires High-Quality Non-Shrink Grout
Precision grouting needs a grout that flows easily into gaps, fills voids completely, resists shrinkage, and cures at predictable strengths. If the grout shrinks or settles, it may cause misalignment, voids under base plates, or uneven load transfer — potentially leading to structural or mechanical issues. Choosing a proven non-shrink grout product ensures consistent performance, accurate leveling and long-term reliability.
Key Properties to Check in a Precision Grout Product
When selecting a non-shrink grout for precision applications, the product should offer:
- High flowability or good pour-ability for filling narrow gaps and under baseplates
- Low shrinkage or compensated expansion during curing
- High early and long-term compressive strength
- Good bonding to concrete and steel (where applicable)
- Dimensional stability after curing — minimal settlement or cracking
- Compatibility with local climate conditions (humidity, salt-air in coastal areas, etc.)
Top 5 Non-Shrink Grout Products for Precision Grouting
Below are five reliable non-shrink grout products widely used for precision grouting — suitable for machinery beds, base plates, anchor bolts, structural repairs, and void filling.
1. SikaGrout 212 (Sika)
A well-known cementitious non-shrink grout, SikaGrout 212 is free-flowing, easy to mix and ideal for precision grouting applications. It offers controlled expansion, high compressive strength and excellent bonding — making it suitable for base plate bedding, column supports or heavy machinery grouting.
2. Fosroc Renderoc HSXtra (Non-Shrink / High-Strength Grout)
Renderoc HSXtra by Fosroc is a high-strength, controlled-expansion grout designed for structural grouting and precision works. Its flowable consistency allows for void filling and anchoring, providing stable, non-shrinking performance even under heavy load — appropriate for heavy base plates, load-bearing columns and concrete repair works.
3. a.b.e. Non-Shrink / Shrinkage-Compensated Grout (a.b.e. Mauritius)
From a.b.e. Construction Chemicals — a trusted name in construction chemistry — their shrinkage-compensated grout is suitable for precise structural grouting, anchoring and void filling. It gives consistent strength development, stable curing and minimal volumetric change after hardening.
4. Palco Trading “NanoGrout GP” / Equivalent Free-Flowing Grout
Palco Trading supplies free-flowing non-shrink grout products (for example “NanoGrout GP” or similar) suitable for light to medium structural grouting works. These grouts have good flowability — filling under-plate voids and uneven bases — ensuring proper load transfer and leveling, which is critical for precision grouting applications.
5. Local Ready-Mix / Imported Non-Shrink Grout from Specialist Distributors (via AGW Trading / Local Suppliers)
Some local distributors and specialist chemical suppliers import or supply prepared non-shrink grout mixes tuned for Mauritian conditions. These local grout products are often used for custom grouting, renovation works and structural patches — offering flexibility, quick supply and good performance for precision grouting needs.
Frequently Asked Questions
1. Can precision grout be used under heavy machinery base plates?
Yes — products like SikaGrout 212 or Fosroc Renderoc HSXtra are designed for heavy load-bearing base plates and offer high compressive strength needed for such applications.
2. Does non-shrink grout require special mixing or curing?
It requires correct water ratio, clean mixing, proper vibration or flow technique, and adequate curing time to maintain its non-shrink properties and strength development.
3. Is it possible to use non-shrink grout in humid or coastal climates like Mauritius?
Yes — provided you use quality grout from reliable suppliers and follow correct mixing, application and curing guidelines suited for high humidity and salt-air exposure.
4. Should precision grout have a flowable consistency?
Yes. For precision grouting under plates or in tight voids, flowability ensures proper filling and bonding, reducing void formation and settlement risks.
5. How to confirm grout suitability before ordering?
Check technical data sheet for compressive strength, expansion/shrinkage data, flow or slump values and compatibility with your concrete or structural requirements.
