Hydroshponka P-3

The P-3 hydrosponk is used for sealing and waterproofing of movable joints in monolithic construction of buried and underground structures. Hydraulic pads are used in hydraulic structures (reservoirs, canals, dams, pools, etc.), as well as for waterproofing joints of foundations, foundations, tunnels, multi-level parking lots and other underground structures. They are made of thermoplastic elastomer TPE (EPDM) or plasticized PVC polyvinyl chloride-P. The U-shaped shape of the hydraulic key allows you to clearly install the key in the design position, using, for example, a sheet of expanded polystyrene, on which the key 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 deformation joints of monolithic reinforced concrete structures
• in particularly important constructions, it is supplemented with an internal or lower external hydraulic spar
• withstands small water pressure inside and outside
• suitable for all kinds of designs
• they are delivered in bays of 25 m.p.
