Hydraulic Stem AquaStop (AquaBarrier) DV-320/40 (PVC) is a deformation inner dowel made of polyvinyl chloride, used to seal expansion joints in the construction of buried and underground structures, 320 (mm) – total width of the waterproofing key, 40 (mm) , filled with expanded polystyrene.

Hydraulic key DV 320/40 is made of PVC, which allows to provide a more durable weld, withstanding a greater water pressure and providing rigidity of the construction, but reducing the temperature range of application.

Mounting of waterproofing keys made on the basis of PVC is carried out with the help of special equipment, either “Tops for welding water-sticks”, or a conventional hand-held hot air device, used, as a rule, for welding PVC membranes.
