AKVASTOP PNR swelling rubber profile — seal for construction joints
PNR is a hydrophilic rubber profile under a protective lacquer: the lacquer breaks down in the alkaline environment of concrete or on prolonged contact with water, after which the rubber swells and locks the joint. The PNR 20×4 Standard grade (green) swells by at least 500 % and withstands 14 atm, PNR 20×4 Econom (blue) — 300 % and 10 atm, and there is also a round PNR Ø8. The profile is used in construction joints of foundations, basements, pools and hydraulic structures, in joints of collector tunnels, manholes and tunnel lining segments, and at utility penetrations; installation is possible at temperatures from −40 to +50 °C.
