The Krystol T1 & T2 Waterproofing System is a cementitious, brush-applied, treatment for concrete. Krystol T1 & T2 contain the proven world-renowned Krystol waterproofing chemicals. Krystol T1 is applied to the concrete first, followed by KRYSTOL T2. When applied in accordance with manufacturer's specifications, the Krystol system is warranted for use in place of conventional waterproofing systems.

Krystol T1 & T2 react chemically within the concrete mass to form billions of needle-like crystals which block the pores, voids and microcracks in concrete. Presaturation and subsequent re-wetting of the surface will cause deeper diffusion of the organic chemicals and formation of crystals at greater depth.
