The ND 240 hydraulic gasket is used for sealing and waterproofing movable joints in monolithic construction of buildings, including foundations, underground parking lots, tunnels, canals, etc. It is mounted directly on the formwork sheet. It is used in hydraulic structures - reservoirs, canals, dams, swimming 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 TRE (EPDM) or plasticized PVC-p polyvinyl chloride.
- allows you to securely embed in a concrete structure
- the presence of ribs on the locking plane prevents the penetration of moisture into the structure
- the presence of a deformable area allows you to perceive deformations of reinforced concrete structures without breaking the tightness
- it is used for sealing between two concrete structures
- in particularly important constructions, it is supplemented with an internal hydraulic gasket
- it can be used in structures with special requirements to ensure tightness
- withstands high water pressure inside and outside
- suitable for all kinds of designs
- the hydraulic shponka is supplied in rolls of 20 m.p.

Installation procedure and rules:
- The hydraulic key is installed in the design position, so that the middle of the hydraulic key is in the center of the expected deformation seam.
- Fastening is carried out directly to the formwork.
- Holes for fastening are allowed to be made only in the extreme zone of the hydraulic dowel, behind the extreme anchor.
- The fastening step is 200-300 mm, symmetrically on both sides.
- Additional fastening is carried out in the same way to the reinforcing frame with a knitting wire.
- The spigot is connected by welding, by heating the ends of the spigot in a special conductor (for each spigot – an individual conductor) or with the help of an industrial hair dryer or a flat Ten.
- The temperature of adhesion is about 200 ° C (chosen experimentally).
- To connect the keys by the "cold" method, glue is used, for example, a one-component pasty glue based on the silane-modified InnoElast polymer.
Blue PROTEX ND 240 PVC hydro-shponka is an irreplaceable helper in sealing and waterproofing movable joints during construction.
It does not matter whether you are building buildings, foundations, tunnels or canals - this hydraulic key allows you to reliably monopolize it in a concrete structure.
What makes this hydro key so unique?
First, its closing plane has ribs that prevent the penetration of moisture inside the structure.
Thus, you can be sure of reliable tightness.
In addition, the presence of a deformed section allows this hydraulic key to perceive deformations of reinforced concrete structures without breaking its tightness.
It also effectively seals between two concrete structures.
If you work with particularly important constructions, where tightness is the main requirement, the ND 240 PVC water plug can be supplemented with an internal water plug.
This hydraulic key also withstands high water pressure both externally and internally.
Its reliability and applicability are suitable for all types of structures.
ND 240 PVC hydro-shponka is supplied in rolls 20 meters long.
