Easy installation for shortened construction period! Bentonite concrete joint waterproofing material.
"Kuni Seal C-31" is a waterproofing material that is very easy to install, as it is wrapped in a water-soluble film on the surface. It can be applied simply by wetting it and placing it on the installation surface, pressing it down, without the need for special tasks like nailing. The bentonite particles that come into contact with water expand while following the fine gaps in the concrete, completely filling the water paths and allowing it to withstand high water pressure. Additionally, because the fine particles expand while releasing pressure, it does not generate large pressures that could crack the concrete. 【Features】 - Can be applied to all types of uneven surfaces - Characteristics that do not degrade in performance for semi-permanent use - No special surface treatment or caulking preparation required - Efficient end joints For more details, please contact us or download the catalog.
