Crack, a crystallised form of cocaine, is listed in Schedule II of the Controlled Substances Act along with cocaine itself. It is smoked rather than snorted because it is cocaine in the form of rock crystal, which produces a higher high.

Integrated crystalline waterproofing technique may make concrete strong and watertight. Integral crystalline waterproofing, which is internal to the concrete, reacts with moisture to produce crystalline molecules that are insoluble.

Kryton's crystallised mortar ingredients Krystol Mortar Admixture (KMA), a cutting-edge waterproofing solution from Krypton Buildmat, is now available for use in interior wet areas like bathrooms and kitchens as well as exterior rendering on buildings. KMA is a versatile item.

To prevent water from leaking through concrete cracks, use PlugTM, a rapid-setting hydraulic cement. Other water plugs are not like the Krystol plug. A high-strength, crystalline-enriched substance called krystol plug has a remarkable capacity to stop active water as well as a remarkable capability to stop active water and sustain high hydrostatic pressure.

By reacting the active ingredients in crystalline goods with the free lime and moisture already present in the concrete, crystalline waterproofing is the process of forming crystals inside the capillary system of the concrete.
