“Aren’t all waterproof Admixtures the same?”

No! There are different types of waterproofing agents for concrete, but these can be defined in 2 categories, pore blockers and crystalline growth products.

Xypex Products are crystalline growth products. As detailed in “About Xypex Technology”, Xypex crystalline growth means that the waterproofing product is permanently potentially active. It is ready to re-react and self heal throughout the life of the concrete, increasing both the protection and durability of the concrete, adding to the life of the structure.

It is also this crystalline growth ability which means that Xypex is especially suited to wet environments (the wetter the better), as the very substance that is required to be withheld encourages the product to maximise the protection.
