Repair gidroponka series

 

They are used for waterproofing expansion joints when mating with existing concrete structures. It is used in the monolithic construction of buildings, including foundations, underground parking lots, tunnels, channels, etc. The repair hydraulic spar is fixed to the existing concrete structure, the free part of the hydraulic spar is loosened to the reinforcement frame of the poured structure, immediately before pouring concrete.  

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

Repair hydraulic spoons of the PO series are designed to seal the expansion joints between the finished railway structure and the poured structure. The absence of fixing anchors on one side of the hydraulic spar, allows you to hermetically glue the U-shaped hydraulic spar to the finished railway structure. For reliable fixation of the hydraulic spool, a metal strip is used, which is fixed from the inside of the hydraulic spool with dowels. The U - shape allows you to clearly install the hydraulic spar in the design position, using an elastic sheet material, such as a Styrofoam plate, on which the hydraulic spar is "put on". The presence of ribs on the locking plane prevents the penetration of moisture into the structure.

  • it is used in the locations of the expansion joints of monolithic reinforced concrete structures, in particularly important structures it is supplemented with an internal or external repair hydrospin;
  • 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.
