Frequently Asked Questions (FAQ)
1. What does “non shrink” mean in a grout product?
Non shrink grout compensates for shrinkage during curing, often exhibiting zero shrinkage or slight controlled expansion.
2. Are all non shrink grouts the same?
No, performance varies by formulation, strength, and application focus.
3. Where are non shrink grouts most commonly used?
They are widely used for base plates, machinery bases, anchor bolts, and structural repairs.
4. Do non shrink grouts need special curing?
Yes, proper curing improves strength and reduces cracking.
5. Can non shrink grout be pumped?
Some products can be mixed to pumpable consistencies for large or hard-to-reach areas.
