About MC-Bauchemie MC-Grout EP

MC-Grout EP is MC-Bauchemie’s answer to a problem every plant engineer knows well: the point where a machine transfers its load into the foundation is only as good as the material filling that gap. Cementitious grouts do the job in ordinary settings, but under high dynamic loads, near chemical spillage, or where every hour of downtime is costly, they can fall short on strength, bond and durability. MC-Grout EP is a solvent-free epoxy system supplied as three matched components, a resin, a hardener and a graded silica aggregate, that combine into a dense, high-strength mortar built to carry demanding static and vibrating loads.

Once mixed and placed, it develops compressive strength in the range of 80 to 100 MPa by seven days and bonds to sound concrete at over 3.0 MPa, all while curing with essentially no net shrinkage so the baseplate stays in full contact. Because there is no solvent, there is no VOC release and no shrinkage from solvent loss. Space Arc Engineering supplies and applies MC-Grout EP across Delhi NCR and Pan-India, so contractors and consultants get both the genuine material and trained site execution from a single point of contact.

The technical insight

The strength of an epoxy grout comes from how three things work together. The resin and hardener react to form a cross-linked polymer matrix, and the graded silica aggregate is the load-bearing skeleton dispersed through it. The manufacturer supplies the aggregate pre-graded so that fine and coarse particles pack tightly, minimising the volume of neat resin, which is the part most prone to shrinkage and creep. That dense packing is why MC-Grout EP reaches 80-100 MPa quickly and shows effectively zero net shrinkage: there is simply less resin to move. The cross-linked network is also chemically inert, so dilute mineral acids, alkalis, oils, fuels and many solvents cannot break it down the way they attack cement paste. The trade-off is exothermic heat and a short working window, so the 20-40 minute pot life at 23 degrees C is a real constraint, not a formality, and lifts must be sized to control heat build-up in thick pours.

Where it is used

• Grouting under machine baseplates in chemical and process plants where spillage and vibration are routine
• Fixing anchor bolts and chemical anchors that must resist pull-out under load
• Repairing machine foundations exposed to aggressive chemical environments
• Bedding structural steel base plates for reliable load transfer to concrete
• Grouting rail fastenings and crane-rail anchors subject to repeated dynamic loading
• Precision repair and re-bedding under vibrating, rotating or reciprocating equipment
• Filling voids beneath pumps, compressors and turbines demanding high early strength
• Anchoring and bedding where chemical resistance and durability outrank cost

Key advantages

• High early compressive strength of 80-100 MPa at 7 days for fast return to service
• Strong bond to concrete exceeding 3.0 MPa for dependable load transfer
• Effectively zero net shrinkage, keeping the baseplate in full contact
• Solvent-free with no VOC emission, suited to enclosed plant areas
• Resists dilute mineral acids, alkalis, oils, fuels and many solvents
• Three-component pre-weighed packs remove site batching errors
• Carries high dynamic and vibrating loads where cementitious grout struggles
• Backed by Space Arc supply plus trained application across Delhi NCR and India

Limitations & considerations

• Short pot life of 20-40 minutes at 23 degrees C demands prompt, organised placing
• Exothermic cure limits pour depth per lift; thick sections may need staged placement
• Higher material cost than cementitious grout, so it is best reserved for genuinely demanding duties
• Sensitive to temperature: cold slows cure while heat shortens working time further
• Requires clean, sound, dry substrate and correct surface preparation for full bond
• Not intended for large-volume mass fills where a cementitious grout is more economical

How we position MC-Bauchemie MC-Grout EP

MC-Grout EP sits at the high-performance end of the grouting range, chosen when loads are dynamic, chemistry is aggressive, or early strength matters more than cost. For everyday machine-base and anchor grouting where a cementitious grout is sufficient, pair it with a flowable non-shrink cementitious grout instead to control budget. Within the same duty, MC-Bauchemie’s own MC-DUR Grout family offers alternatives graded by pour depth, low-viscosity thin-section options through to low-exothermic grades for deeper lifts, if you need a different thickness envelope. Across our other brands, Fosroc’s Conbextra epoxy grout line and Sika epoxy grouting systems cover comparable duties; talk to Space Arc if you want us to match the grade to your gap, load and site conditions.
