External hydraulic spool for working joints of the HP series

 

They are used for sealing and waterproofing process joints in the monolithic construction of buildings, including foundations, underground parking lots, tunnels, channels, etc. They are mounted directly on the formwork sheet from the expected water pressure.             

They are made of thermoplastic elastomer TPE or plasticized polyvinyl chloride PVC-P.

The shape of the hydrospin allows you to securely embed in the concrete structure, the presence of ribs on the locking plane prevents the penetration of moisture into the structure.

  • it is used during the break of concreting of monolithic reinforced concrete structures, in particularly important structures it is supplemented with an internal hydraulic spar;
  • it can be used in structures with special requirements to ensure tightness;
  • withstands high water pressure from outside;
  • easy to install, no need to change the reinforcement cage;
  • suitable for all kinds of designs;
  • they are delivered in rolls of 25 m. p.;
  • if necessary, elongation and to perform spatial nodal transitions-are welded in the conductor, construction hair dryer, flat heating element or glued together.
