All COLORED block made in Florida Contains integral waterproofing. The assumption you MUST make is that if the block is not colored it will not contain integral waterproofing. EVERY block that is used in a single wythe installation SHOULD contain integral waterproofing --- even if it is going to be painted or sealed. So…. If you are designing a single wythe wall that does not contain integral color be sure to request integral waterproofing!! ONE more thing --- EVERY single wythe wall SHOULD be painted or sealed.
Remember – Single Wythe -- Integral Waterproofing --- Painted and Sealed -- ALWAYS.
