Non-Shrink Grouts & Anchoring Products in India
Non-shrink grouts and anchoring products are the load-transfer link between a structure and the equipment, columns or reinforcement it carries. Whether you are bedding a turbine baseplate, filling a stanchion pocket, grouting post-tensioning ducts or fixing rebar dowels into hardened concrete, the grout or anchor you choose decides how reliably load, vibration and dynamic forces are transferred without voids, cracking or settlement. This category spans three families: cementitious non-shrink grouts for general baseplates and foundations, high-strength epoxy precision grouts for heavily loaded or chemically exposed machinery, and resin anchoring systems for fixing bars and bolts. Specifications typically reference ASTM C1107 for non-shrink grouts and EN 1504-6 for anchoring of reinforcement. Because no single brand is best for every duty, specifiers and contractors benefit from comparing across manufacturers. Space Arc Engineering is an authorized project distributor and applicator in India for Fosroc, Sika, Master Builders Solutions, STP, UltraTech and Dr. Fixit, supplying genuine, fully traceable material from all major grout and anchor ranges. Beyond supply, our team provides product selection support, method statements, trial mixes and trained application crews, so the right grout reaches site with the technical backing to install it correctly the first time.
Grout & Anchor Technologies: Cementitious, Epoxy and Resin Anchors
The category divides into three core technologies. Cementitious non-shrink grouts (Fosroc Conbextra GP1/GP2/GP2N, SikaGrout 212 and 214, Master Builders MasterFlow 928, UltraTech PowerGrout) are pre-bagged blends of special cements, graded fillers and shrinkage-compensating additives. They are the workhorse choice for baseplates, foundations, column bases and general void filling, mixed on site to flowable consistency. Epoxy precision grouts (Fosroc Conbextra EP series, MasterFlow 9400) are three-component resin systems delivering very high early and ultimate strength, excellent fatigue and vibration resistance, and chemical resistance, making them suited to critical machinery, high dynamic loads and aggressive process environments. Resin anchoring systems (Fosroc Lokfix in pourable and thixotropic grades) are polyester or epoxy resins used to bond rebar starter bars, dowels, bolts and rails into drilled holes. Choosing the correct technology is the first and most important selection step: cementitious for cost-effective static and moderate dynamic loads, epoxy where strength, chemical exposure or vibration is demanding, and resin anchors for post-installed fixings.
Key Selection Criteria for Grouting and Anchoring
Match the product to the duty using a few decisive parameters. Loading: static baseplates suit cementitious grouts, while reciprocating compressors, turbines and heavy dynamic loads point to epoxy. Flowability and gap: thick sections may use a flowable cementitious grout (often extended with approved aggregate per the data sheet for deep pours), while thin or congested gaps need a high-flow precision grade. Strength and early gain: where equipment must be commissioned quickly, look at early-age strength rather than 28-day figures alone. Exposure: marine, chemical or fuel-contact environments favour epoxy chemistry. Anchoring substrate and orientation: horizontal-down holes accept pourable resin grades, whereas overhead and horizontal fixings need a thixotropic (non-sag) grade. Standards and approvals: confirm compliance with the project specification, commonly ASTM C1107 for non-shrink grouts and EN 1504-6 for anchoring. Finally, account for temperature at the time of placing, since both pot life and set are temperature sensitive. Space Arc helps shortlist grades against these criteria and can arrange trial mixes before bulk order.
Application & Industry Contexts
Grouts and anchors appear across virtually every construction and industrial sector. In power, steel, cement and process plants, epoxy and high-flow cementitious grouts bed turbines, generators, compressors, mills and crusher bases where zero settlement and vibration resistance are critical. In general building and infrastructure, cementitious grouts fill column baseplates, bearing pads, crane rails, anchor pockets and precast connections, while resin anchors fix starter bars and dowels for extensions and retrofits. Bridge and PT works use specialist duct grouts to protect post-tensioning tendons. Water-retaining and marine structures favour epoxy systems for chemical durability. Each context carries its own placing challenge, whether it is reaching the far edge of a large baseplate in a single pour, grouting in high ambient temperatures, or achieving full hole encapsulation for a deep anchor. Selecting the right consistency, pot life and placement method, with a competent crew, is what prevents voids and bleeds that compromise load transfer.
Common Problems Solved by the Right Grout or Anchor
The right specification and application directly eliminate the failures seen on poorly grouted jobs. Drummy or hollow baseplates from grout shrinkage or incomplete filling are prevented by genuine non-shrink grades placed to a correct head and flow distance. Premature cracking under dynamic load is addressed by selecting an epoxy precision grout matched to the machine’s forces. Slow commissioning is solved with rapid-strength grades. Anchor pull-out and rebar slippage are avoided by using the correct resin grade, hole cleaning and embedment depth per the data sheet. Bleeding and segregation in deep pours are managed with the manufacturer-approved extension method rather than ad-hoc site water additions. Many of these defects trace back to either the wrong product family or incorrect mixing and placing, which is why authorized supply paired with trained applicators matters. Space Arc supplies the correct genuine grade and can deploy crews who follow the manufacturer method statement, reducing rework and warranty risk.
How to Choose — Quick Selection Guide
| If you need… | Recommended approach |
|---|---|
| General baseplates, column bases and foundations under static load | A general-purpose cementitious non-shrink grout such as Fosroc Conbextra GP2, SikaGrout 214, Master Builders MasterFlow 928 or UltraTech PowerGrout, mixed to flowable consistency. |
| Critical machinery with high dynamic loads or vibration (turbines, compressors, mills) | A high-strength epoxy precision grout such as Fosroc Conbextra EP series or Master Builders MasterFlow 9400 for fatigue and vibration resistance. |
| Aggressive chemical, marine or fuel-contact exposure around the foundation | Epoxy grout chemistry (Conbextra EP / MasterFlow 9400) for chemical resistance, rather than a standard cementitious grade. |
| Fixing rebar starter bars or bolts into vertical-down drilled holes | A pourable-grade resin anchoring grout such as Fosroc Lokfix (pourable), following hole-cleaning and embedment guidance. |
| Anchoring into overhead or horizontal holes where the resin must not sag | A thixotropic (non-sag) resin anchor grade such as Fosroc Lokfix (thixotropic grade). |
| Fast equipment commissioning with limited downtime | Select a rapid early-strength grout grade and confirm early-age strength data with Space Arc rather than relying on 28-day values. |
| Deep or large-gap pours needing extra volume | Use a flowable cementitious grout extended with manufacturer-approved aggregate per the data sheet; never add unspecified site water to gain volume. |

Frequently Asked Questions
What is the difference between cementitious and epoxy non-shrink grout?
Cementitious non-shrink grouts (e.g. Conbextra GP, SikaGrout, MasterFlow 928, UltraTech PowerGrout) are cost-effective and suit general baseplates and static-to-moderate dynamic loads. Epoxy precision grouts (e.g. Conbextra EP, MasterFlow 9400) offer much higher strength, fatigue and chemical resistance for critical machinery and aggressive environments. Choose cementitious for everyday foundations and epoxy where loads, vibration or exposure are severe.
Which grout product is best for grouting a turbine or compressor baseplate?
Heavily loaded, vibrating equipment such as turbines and reciprocating compressors generally calls for a high-strength epoxy precision grout like the Fosroc Conbextra EP range or Master Builders MasterFlow 9400, which resist fatigue and dynamic forces better than cementitious grades. For lighter, predominantly static machinery a high-flow cementitious grout can be sufficient. Space Arc can match the grade to your machine loads and ambient conditions.
Which anchoring product should I use for rebar dowels and bolts?
For post-installed rebar starter bars, dowels and bolts, a resin anchoring grout such as Fosroc Lokfix is used. Use a pourable grade for vertical-down holes and a thixotropic non-sag grade for overhead or horizontal holes. Correct hole cleaning, diameter and embedment depth per the data sheet are essential for full anchorage strength.
What standards do non-shrink grouts and anchors comply with?
Non-shrink cementitious and epoxy grouts are commonly specified to ASTM C1107, and resin anchoring systems to EN 1504-6 for anchoring of reinforcement. Duct grouts for post-tensioning reference EN 447. Always confirm the exact clause in your project specification; Space Arc can supply the matching genuine grade and its technical data sheet.
Can I add extra water or aggregate to a grout to make it go further?
Never add unspecified site water, as it causes bleeding, segregation and loss of strength. Some flowable cementitious grouts can be extended with manufacturer-approved aggregate for deep pours, but only at the dosage and section thickness stated on the data sheet. For large or deep gaps, ask Space Arc for the correct extension method or a more suitable grade.
