This is a new one to me. The specification dictates minimum bond and tensile strength, along with a few other parameters. Anyone ever used this type of mix?
Redundancy seems to be the current tread in the modern masonry world.We do add Dry-Blok to our mix which is confusing almost contradicting as the Type-S Giant mix we use states waterproofing agent add on the bags. Confused by the need for double water proofing additives? We are laying 4" split face that claim to have waterproof mixed in to the batch or applied some where in manufacturing process of block. Again JDK
