I would like to get some assurance that the crystalline waterproofing process doesn't interfere with the air-entrainment process. Especially in the admixture application.

When applied as a coating to a hardened concrete structure, crystalline waterproofing materials will not affect the air-entraining system in the concrete. The crystalline structure will form in the capillary tracts of the concrete but will not fill up air entraining bubbles in the concrete as they are physically separated from the capillary tracts. When used as an admixture one particular crystalline waterproofing material will entrain air (Kryton) and the ready mix supplier will have to make an adjustment but the crystalline waterproofing admixtures from other manufacturers have no effect on the amount or quality of the entrained air.
