What is a waterproofing admixture?

What is a waterproofing admixture?

Waterproofing admixtures are porous materials that have the ability to absorb water and water-borne contaminants. Hydrophobic and pore blocking ingredients react with products of the cement hydration process to produce a hydrophobic material which resists external water, decreasing absorption into the concrete.

What is a Kim mix?
