Swelling bentonite profile. Aquastop (Type PNB), “lux” is used for sealing technological seams, various joints in the process of conducting concrete works, for sealing joints of prefabricated and reinforced concrete structures, and for sealing communication types of buildings and structures and cracks in building structures. The profile is characterized by a high limiting hydrostatic pressure (22 atm) in comparison with other swelling profiles (including rubber), as well as a larger volume expansion than standard bentonite swelling profiles.

The swelling rubber profile of PNB Lux can be used in chemically active environments as well as buildings with increased requirements for environmental safety. Among the advantages of PNP profile, it is also important to develop high durability, as well as retain properties for multiple cycles of volume change, the protective coating of the profile ensures that there is no deformation of the construction structure at the initial time of hardening of concrete.

From the profile “Standard” differs by a smaller increase in volume when swelling (2 times), color and resistance to hydrostatic pressure (14 y “standard”, 10 y “Econom”
