Crystalline Surface Applied Waterproofing T1

Krystol® T1 and T2

Surface-Applied Concrete Waterproofing
Surface-Applied Concrete Waterproofing with Krystol® T1 and T2

Recently built structures and heritage buildings need water protection too! Whether you're waterproofing a new structure or repairing leaks, Krystol's concrete waterproofing treatments allow you to turn existing concrete into a waterproof barrier reliably and cost-effectively. The result is permanently waterproof concrete — even against strong hydrostatic pressure.

How It Works

Krystol T1/T2 is a simple, two-step cementitious slurry system that is brush-applied to existing concrete structures. After application, chemicals from Krystol T1/T2 are absorbed into the concrete through capillary action (the natural wicking movement of liquids through a porous structure) and diffusion (the natural movement of chemical molecules.) Since the majority of active crystalline chemicals migrate into the concrete within the first 28 days, the surface-applied slurry can be completely removed from the surface after this time with no impact to its waterproofing properties.

Whenever waterproof crystalline masonry is needed

Krystol T1/T2 is warranted for use in place of conventional waterproofing systems. It can be used in recently poured or decades old concrete. Some of it's recommended uses are in concrete foundations and walls, elevated slabs and ramps, parking structures, water towers and bridge decks.

Product Benefits
