Q: What is the price of a 25 kg bag of non shrink grout like Conbextra GP2 in India?

Pricing for a 25 kg bag of general-purpose non shrink grout moves with brand, grade, quantity and location, so any single figure dates quickly. GP2-class cementitious grouts typically sit in an accessible mid-range, with epoxy and aggregate-loaded grades costing more. Because we stock all eight brands, we can compare equivalent grades and give you a current, project-specific rate. Share your gap, volume and site for a same-day quote.

Q: What is the difference between GP1, GP2, GP3 and GP4 grout?

They form a grade ladder mainly distinguished by gap thickness and aggregate loading. GP1/GP2 are finer, free-flow grades for thinner base-plate gaps; GP3 and GP4 carry coarser aggregate for thicker pours, controlling heat and shrinkage in deep sections. Strength class and flow also vary. The right grade depends on your gap and load — we help you match it and supply the equivalent across brands.

Q: Should I use epoxy grout or cementitious grout for a machine foundation?

It depends on the duty. Cementitious non shrink grout suits most static and moderately dynamic foundations and is cost-effective. Epoxy grout is specified where there is chemical attack, high impact, fatigue, vibration or very thin high-strength bedding — common under presses, compressors and reciprocating machines. For a turbine or compressor base, share the load and exposure data and we will recommend the correct system on merit.

Q: Which grout is best for machine base plate grouting?

Use a free-flow, high-strength non shrink grout that achieves full contact under the plate with no voids, so load transfers uniformly. Cementitious free-flow grades cover most cases; switch to epoxy for dynamic, chemical or thin-gap duties. Detailing — rebated edges, head height and single-direction pour — matters as much as the product. Tell us the equipment and base size and we will specify grade plus method.

Q: What chemical anchor should I use for rebar dowelling, and how is it priced?

Match the chemical anchor resin to hole condition, embedment depth and edge distance — epoxy systems (e.g. Lokfix-type) for high-load structural dowelling, faster resins for lighter fixings. Pricing depends on cartridge size, resin type and quantity. As distributors we stock the common anchoring chemicals and can size the system to your design pull-out and supply at a competitive rate — send your bar diameter and embedment for a quote.

Q: Do you supply PT / duct grout to IS 9102 for bridges and metro?

Yes. For post-tensioning and PSC duct grouting we supply thixotropic, bleed-resistant grouts formulated to fully encase strands and protect against corrosion, consistent with IS 9102 and IRC durability intent. These differ from base-plate grouts in flow, bleed and chloride control. Share your duct geometry, strand layout and spec and we will recommend a compliant product and supply pan-India.

The short answer

What is non-shrink grout — and why getting the selection right matters

A non shrink grout is a flowable, pre-bagged cementitious or epoxy material engineered to fill the gap between a structure and a load-bearing element — a machine base plate, anchor bolt pocket, column base or precast joint — while developing controlled positive expansion so it transmits load uniformly without shrinking away and leaving voids. Unlike ordinary sand-cement mortar, it is dimensionally stable, develops high early and ultimate strength, and is formulated to IS 9102 / ASTM C1107 performance, which is exactly why specifiers reach for branded systems rather than a site mix.

Choosing the wrong system is a costly mistake. An under-specified grout under a turbine, compressor or press foundation can crush, debond or pump out under dynamic load, leading to vibration, misalignment and equipment damage that dwarfs the grout cost. Pick a cementitious grout where you needed an epoxy grout (chemical attack, high impact, fatigue) and it fails early; over-spec an epoxy where cementitious would do and you burn budget. The right call depends on load type, gap thickness, chemical exposure and buildability — the four questions this hub helps you answer.

The same logic runs through chemical anchoring and rebar dowelling (matching resin to substrate, hole condition and edge distance), PT/duct grouting for bridges and metro (where corrosion of strands is a durability risk), and the admixtures that control workability, set and waterproofing in the concrete itself. We help you specify all three correctly and supply the matching products.

The grouting, anchoring & admixture sub-categories

Eight focused areas that cover almost every grouting, anchoring and admixture enquiry we receive across Delhi NCR and pan-India. Each links to deeper guidance and product options across all stocked brands.

🧱

Grout product families & grades

Understand the GP1/GP2/GP3/GP4 cementitious ladder and the EP epoxy series — flowable vs free-flow, fine vs aggregate-loaded, and where each grade fits by gap and strength. Families like Fosroc Conbextra GP2/GP3/GP4 and SikaGrout 214 map onto this logic.

Best for: specifiers and contractors choosing a grade by gap thickness and strength class.

⚖️

Cementitious vs epoxy grout selection

A merit-based comparison by load type: static vs dynamic, impact, fatigue and chemical exposure. Cementitious for most static foundations; epoxy (e.g. Conbextra EP) where chemicals, vibration or thin high-strength bedding demand it.

Best for: machine, press and pump foundations where load type drives the choice.

⚙️

Machine & equipment base plate grouting

Free-flow, high-strength bedding under base plates to achieve full contact and uniform load transfer with no voids. Coverage, fluidity and rebated-edge detailing are everything here.

Best for: turbines, compressors, motors, crushers and rotating equipment.

🔩

Anchoring & rebar dowelling

Chemical anchors and resin systems for rebar dowelling, starter bars and fixing into hardened concrete — matching resin to hole condition, embedment and edge distance. Lokfix P/S/E75 are common reference systems.

Best for: rebar starter bars, façade fixings, retrofits and structural connections.

🌉

Cable / PT / PSC girder duct grouting

Specialised thixotropic, bleed-resistant grouts that fully encase post-tensioned strands inside ducts to protect against corrosion — to IS 9102 / IRC durability intent for bridges and metro.

Best for: PT bridges, metro viaducts, PSC girders and segmental construction.

🕳️

Foundation & anchor bolt pocket grouting

Pourable non-shrink grout for anchor bolt pockets, holding-down bolts and column base plates, locking fixings against pull-out and lateral load. Pocket depth and pour access govern flow choice.

Best for: structural steel bases, pre-engineered buildings and holding-down bolts.

📐

Grout consumption, coverage & water-addition

How to convert pocket or bedding volume into bags, allow for wastage, and add water within the specified band — over-watering is the single biggest cause of strength loss and bleed on site.

Best for: estimators and site engineers planning quantities and mix control.

🧪

Admixtures overview (sub-pillar)

Plasticisers and superplasticisers, accelerators, retarders, and integral waterproofing compounds that tune workability, set time and durability of the concrete itself — to IS 9103 intent.

Best for: RMC plants, large pours and durability-critical concrete.

Decision guide

Four questions to specify the right system

What is the substrate and gap?

Define the base condition (saturated, dry, oily, hardened concrete or steel) and the gap or pocket thickness. Thin gaps may need free-flow or epoxy; thick pours need aggregate-loaded grades like GP3/GP4 to control heat and shrinkage.

What is the exposure and load?

Is the load static (column base) or dynamic (turbine, press)? Is there impact, fatigue, water, fuel or chemical attack? Dynamic and chemically aggressive duties push you toward epoxy or higher-strength cementitious grades.

Is there movement or chemistry to resist?

For PT ducts and anchoring, corrosion protection of steel is the governing durability criterion. For anchoring, match resin chemistry (epoxy vs vinylester) to hole condition, embedment depth and edge distance per the design check.

What are the budget and buildability limits?

Balance material cost against pour access, ambient temperature, working time, and crew skill. We help right-size the grade so you neither over-spec an epoxy nor risk failure with an under-strength cementitious mix.
