Miscellaneous Waterproofing Products
Concrete, although strong, is also a hard sponge—hydrophilic and capable of soaking up water. Special treatments are needed with specialized waterproofing materials. Multiguard Crystal and PrimeShield are products that react with concrete to form billions of crystals, effectively plugging porosity. Being in liquid form, these products can be easily sprayed or brush-applied on a properly prepared surface. Multiguard EP and AquaBlock are epoxy-based but water-dilutable products with high bond strength. Being water-based epoxy, they can be applied on wet or damp surfaces.
