Why use epoxy grout?
/Epoxy grout has excellent adhesion properties to both concrete and steel. Epoxy grout is the only equipment setting material with the ability to resist vertical, horizontal, and axial forces.
What is a monolithic structure?
/A monolithic structure is one that operates as a whole. When epoxy grout is placed between concrete and a steel base plate, a monolithic structure is formed.
Can vibration jump a cold joint in concrete?
/Vibration cannot jump or transfer across a cold joint in concrete.
How soon can I set equipment after concrete is poured?
/Concrete needs to be completely hydrated which is typically 28 days with standard concrete. Concrete could be hydrated faster than 28 days but would need to be tested to verify full hydration.
How soon can I pour grout equipment?
/Assuming the concrete is properly cured, grout can be poured after all concrete laitance is removed.
How do I prepare my concrete foundation for grout?
/A concrete foundation should be prepared for grout by removing all laitance with a chipping hamper with a chisel bit.
What strength of concrete should my foundation be?
/All concrete should have a minimum compressive strength of 4000 psi at 28 days.
How do I prepare my concrete foundation for grouting?
/Remove all laitance with a chipping hammer.
Make sure the concrete is properly hydrated.
Be sure the concrete is free of any oil or contaminants.
Can my equipment foundation be multiple pours of concrete?
/Multiple concrete pours are not recommended as there will be a cold joint between pours and vibration will not transfer across a cold joint.
Can I use a high early concrete mixture for my foundation?
/A high early concrete should only be used with the approval of the equipment user. Consider the use of Gill 33 for quick compressive strength and hydration.
If there is contamination on an existing foundation can I grout over it?
/All existing foundation contamination must be removed by removing the concrete that is contaminated prior to grouting.
Does the expansion joint need to extend into the concrete foundation?
/The expansion joint is generally installed on top of the concrete foundation and below the base plate within the area where the epoxy grout will be poured.
How big should I core holes for anchor bolts in concrete?
/When coring holes in a concrete foundation for anchor bolts, the diameter of the core should be 3 times the bolt diameter.
