uah / roll.

The ND-R 500 hydraulic gasket is used for waterproofing expansion joints when mating with existing concrete and metal structures. It is used in the monolithic construction of buildings, including foundations, underground parking lots, tunnels, canals, etc. The repair hydraulic shingle is fixed to the existing structure, the free part of the hydraulic shingle is loosened to the reinforcement frame of the poured structure, immediately before pouring concrete. They are made of thermoplastic elastomer TRE or plasticized PVC-p polyvinyl chloride.

for sealing the expansion joints between the finished w/b or metal structure and the poured structure
for reliable fixation of the hydraulic strap, a metal strip is used, which is fixed outside the hydraulic strap with dowels
the elasticity of the material makes it possible to clearly install the hydraulic shutter in the design position
the presence of ribs on the locking plane and anchors 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 by a U-shaped repair hydraulic spar of the PO series
They are delivered in rolls of 25 m.p.

Repair (clamping) hydraulic joints of the deformation seam for connecting old and new structures (ND-R)They are used when connecting existing and new structures

Made of elastic polymer materials (PVC)
They are used for sealing the deformation seam in monolithic construction of buildings, including foundations, underground parking lots, tunnels, canals, reservoirs, etc.
Due to its shape and the presence of special ribs, the ND-R hydroshpon is installed in the place of the intended seam and reliably protects the structure from moisture penetration
It is fixed with a flat part to the existing structure, the second part (with anchors) is mounted to the reinforcement frame before pouring concrete

Advantages:the only possible option for sealing the seam between the existing and new construction

reliable fastening in concrete
suitable for all types of structures in industrial and civil construction
the presence of a compensating node allows you to perceive deformations of reinforced concrete structures without breaking the tightness
withstands high water pressure inside and outside
wide operating temperature range from -40⁰C to 70⁰C
high chemical resistance
service life of at least 25 years
the product is environmentally friendly

How to install a waterstop?

The hydraulic pin is installed in the design position, so that the middle of the hydraulic pin is in the center of the intended 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
silane modified polymer Innoellast.
