I’ve heard about using crystalline admixture or crystalline materials on top of concrete to fill voids and make the substrate less permeable. When is this desirable, and what is the best way to use these materials?

The best results for waterproofing concrete using the crystalline materials is to have them in the concrete mix. It can be used for concrete water tanks, below ground structures, basement walls where external hydrostatic water pressure may be a concern. The crystalline material can be placed on top of fresh concrete, but the results are not as good.
