MR. JO EP Grout – STD
MR. JO EP Grout – STD Reliable, flowable epoxy grout for machine bases that must stay level and locked under dynamic loads
The problem — why ordinary grouts fail machine foundations
Machines that vibrate, reciprocate or spin (compressors, presses, CNCs, rollers) place dynamic loads on their foundations and anchor bolts. Traditional cement grouts:
- Shrink and crack under cyclic loading,
- Permit micro-movement that loosens anchor bolts,
- Allow moisture/chemicals into voids which accelerates damage, and
- Often require long downtime to cure.
The result: frequent realignments, increased vibration, component wear and costly downtime.
The solution — why MR. JO EP Grout – STD
EP Grout – STD is a three-component, flowable epoxy grout formulated specifically for machine foundation grouting and baseplate levelling. It cures to a hard, cohesive grout that:
- Bonds strongly to concrete and metal baseplates,
- Resists dynamic loads without cracking,
- Provides excellent load transfer across the bearing surface, and
- Achieves serviceable strength far quicker than cementitious alternatives.
In short: you get a machine that stays level, secure and true — reducing maintenance and increasing equipment life.
Job-ready workflow (practical on-site steps)
- Assess & prepare — remove loose concrete, laitance and contaminants. Roughen steel/plate bearing faces if oily or glazed. Ensure formwork or dams are tight to avoid leak-out.
- Dry fit & pre-check — place machine, tighten studs lightly, insert grout dams (rubber/or plywood) around the base where required. Check alignment.
- Mixing — EP Grout STD is a 3-component system. Measure parts precisely and mix Part A + Part B then gradually add the filler (Part C) until uniform. Use a low-speed mixer to avoid air entrainment. Mix only the volume you can place within the grout’s working time.
- Pouring — pour from one side to avoid air traps or use grout pumps for large volumes. Ensure grout flows under bearing areas and bolt pockets. Use vent holes to allow air escape if necessary.
- De-air & compact — for large cavities, a brief vibration or poking with a rod helps eliminate voids; don’t over-vibrate.
- Cure & remove forms — follow product TDS for demould/strip times. Protect from heavy loads until specified cure strength is reached.
- Final torque & commissioning — only perform final bolt torques and alignment checks after grout reaches required strength.
Practical tips & dos/don’ts
Do:
- Do measure by weight for consistent performance and strength.
- Do plan batch sizes to avoid exotherm and premature gel.
- Do dampen very dry concrete slightly if recommended (check TDS).
Don’t: - Don’t pour over contamination — prep is king.
- Don’t try to extend pot life by adding solvents.
- Don’t load the foundation until grout reaches specified handling strength.
Troubleshooting
- Voids under plate → mix/placement technique issue; consider pumping or using a lower batch size and venting.
- Short working time → batch was too large or temperature high; reduce batch size and cool components.
- Poor bond → surface contamination; re-prepare and use a primer if recommended.
ROI — why STD pays back
Fewer re-alignments, reduced vibration-related wear, less downtime for maintenance and a longer service life for bolted assemblies — EP Grout STD typically pays for itself in avoided repairs and improved machine uptime.
