T1 is dry powder when mixed with water becomes a coating that is applied to the inner or outer sides of any concrete or block structure.

Highlights

  • Krystol T1 and T2 contain a unique and proven technology which reacts to grow millions of needle-like crystals deep into the concrete mass; over time, these crystals grow to fill the pores and voids in concrete, permanently blocking the pathways for water
  • Self-seals hairline cracks up to 0.5 mm (0.02 in.), effective against hydrostatic pressure up to 140 m (460 ft.) of head pressure; waterproofing increases with time
  • Waterproofing effectiveness increases with time and the material can; waterproof from any direction (i.e. positive or negative side) this treatment can be applied to old or new concrete
  • Both T1 and T2 waterproofing products are safe for contact with potable water, certified by NSF to NSF/ANSI Standard 61 Drinking Water System components
  • Permanently waterproofs the concrete; increases reliability and quality control; lowers the cost of waterproofing; increased durability and decreases building maintenance and repair costs, these materials are Impervious to physical damage and deterioration and will protect reinforcing steel against corrosion
  • Krystol T1 is typically the first of 2 coats, Krystol T2 is used over T1

Questions & Answers

Can I apply it over self leveling concrete? I used Custom RS for leveling part of my basement. If yes how long I should wait after laying the self leveling?
ByAug 24, 2025
1 Answer | 
Answer This Question

Yes, T1 can be applied over self-leveling concrete however these two criteria must be met: 1. Self-leveling concrete must be open pored to allow for crystal growth. A soak test determines if the pores are open by observing if water soaks into the concrete or stays on the surface. 2. Typically, the surface of self-leveling concrete is shiny, smooth and tight. The surface must be rough and opened to provide a surface area for the T1 to bond to. As always, they must closely follow the T1 application instructions, and the manufacturer instructions of the self-leveling concrete.

    Answer This Question

    Dear CTH, I am not familiar with Rapid Seal. However, if it is Rapid Set you are referring to, the answer is yes. Please follow exact application instruction for the use of T1. For better results next time consider the use of Krystol Plug for plugging active leaks. thank you Greg greg@dryconcrete.com 646 404 7272

      it can be applied to stone, but will work best on concrete or block. The crystallization will only happen at the mortar joint greg

        Answer This Question

        Aaron T1 is always best applied directly to the surface that you intend to waterproof. However, if the mortar is bonded well T1 can work as a surface applied method of waterproofing. Please ee free to email me photos of the condition, I would be happy to help Greg@dryconcrete.com

            Can Krystol-T1 be used on a concrete block retaining wall that will be back filled with dirt?
            BySep 26, 2024
            1 Answer | 
            Answer This Question

            Miles, Yes this is a good use of T1. it can be applied to either side of the block or both. But typically, in this case, if you had access to the soil-side of the wall, apply it there. greg@dryconcrete.com

              There is a plaster like material on my concrete walls. With the solution work through the plastered areas?
              BySep 23, 2024

              Answer This Question

              Jordan, If you plaster was cement based, it could work, but if it was traditional plaster (gypsum/lime/sand) it will not. your best bet would be to remove the plaster, get down to the concrete or block, then apply the material and then re-apply the plaster greg greg@dryconcrete.com

                I used Krystol T1 to waterproof a brick party wall that was seeping moisture. Prep is key and takes some elbow grease, but once the wall was ready the product was easy to work with. I watched Kryton’s YouTube videos first and that helped a lot with mixing and application. Wear a mask when handling it. The powder is dusty and definitely an irritant. It went on solid and covered well. Too soon to judge long-term results, but so far it’s doing what it’s supposed to.

                Product was easy to mix. Made small batches. Easy to apply with concrete brush. Used a small handheld garden sprayer to mist walls while curing. Time will tell with spring rain if concrete block basement walls with weep.

                It is initially expensive. However considering it is a “permanent” coating, (one of very few available), maybe not so expensive in the long term. The crystals continue growing long term locking it in better over time. Also it can be painted over which is good news for my basement floor.

                  It did not work and when we called the company to ask if we should buy more they told us to hire a professional to install the product. If your going to see the product be kind enough to give support to those trying to use it.
