50 lb. Non-Shrink Precision Grout

Great product but not for this application. You would be better off to cut the concrete back so you can re-dig the hole and set with a bag of fast setting concrete. Also, the grout has no rock and it is at least twice the cost of a bag of sak crete.

This will work for that application and as stated on the bag, it does not shrink. The other thing is it doesn't expand either. The one thing is it will not take color the same as concrete.

The primary use for this product is to provide a base for heavy loads. So long as this grout is completely enclosed on all sides and it has a very stable base, then it would seem to be ideal for your project. It has an extremely strong crush strength. But if there might be lateral movement near the edges, or an unstable base, then a simple high strength concrete mix would work as well and in some instances better. .

QUIKRETE® Non-Shrink Grout is an expansive grout suitable only for fully restrained applications. For your application, a mortar is more appropriate, like QUIKRETE® Stone Veneer Mortar or QUIKRETE® Natural Stone Mortar. These products are designed with superior adhesion and less sag, perfect for vertical grouting applications. Both of these products are gray once cured.

The concrete pad will experience plastic shrinkage and expansion as well as curing shrinkage and expansion throughout the curing process. The concrete pad should be fully cured, approximately 28 days, before placement of the QUIKRETE® Non-Shrink Precision Grout to ensure that the desired spacing is maintained to support the beam.

This grout has an extremely high crush strength as long as it is enclosed and on top of something as stable. Your example has neither, so my recommendation would be to scrape away all of the loose dirt and fill the void with a prepared concrete mix, wetted to the thickest that you can thoroughly mix and pour. Be certain that it is completely mixed and then tamp it into the void. A common rule is to wait a week before placing a heavy load on it, but since it is your driveway, that might be difficult, so at least attempt to wait 36 hours or longer if possible I would suggest returning the grout and purchasing a concrete mix.

I think it would be fine, product is strong and easy to work with. I don't see it being an issue

The good thing about no shrink grout is that it doesn't shrink like concrete. This product should work just fine. No need to add any aggregate.

QUIKRETE® Non-Shrink Precision Grout has not been evaluated for sulfate resistance.

I would not recommed it. There are several products out there made specifically for water issues in basement. Once sealed you will then need to use a floor leveling product. Make sure you read the label on the limits of how think you can pour the leveling product. Not all are the same.
