uah / roll.

The ND 320 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 into 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 complemented by 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.

External (external) hydraulic studs for expansion joints ND seriesThey are used for sealing and waterproofing movable joints in monolithic construction of buildings, including foundations, underground parking lots, tunnels, canals, etc. They are mounted directly on the formwork sheet.

The shape of the hydraulic spar allows it to be securely sealed into a concrete structure, the presence of ribs on the plane prevents moisture from entering the structure.

Advantages of using hydroshpons:

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 that are subjected to deformation effects, in particularly important structures it is supplemented with an external or internal hydraulic gasket
it can be used in structures with special requirements to ensure tightness
withstands high water pressure inside and outside
easy to install
suitable for all kinds of designs

How to install a waterstop?

The hydraulic joint is installed in the design position, so that the middle of the hydraulic joint is located in the center of the intended deformation seam.
Fastening is made directly to the formwork. Holes for fasteners are allowed to be made only in the extreme zone of the hydraulic shponka, behind the extreme anchor. The mounting pitch is 200-300 mm, symmetrically on both sides. Additional fastening is also made to the reinforcement frame with knitting wire.
The connection of the key is made by welding, by heating the ends of the key in a special conductor (for each key there is an individual conductor) or using an industrial hair dryer or a flat heating element. The temperature of the spike is about 200 ° C (selected experimentally). To connect the dowels by the "cold" method, glue is used, for example, a one-component paste-like glue based on the silane-modified polymer InnoElast.
