KRYSTAL SEAL is a single component crystalline cement
slurry for concrete treatment. When mixed with water and
applied onto the substrate, it reacts chemically to form
insoluble needle-shaped crystals that fill capillary pores and
micro-cracks in the concrete and protect against the
passage of water. Unlike the membrane type waterproofing,
Krystal Seal becomes part of the concrete therefore it can
be used as both positive and negative side waterproofing.
