Installation procedure and rules:

• The hydraulic shutter is installed in the design position, so that the middle of the hydraulic shutter is located in the center of the intended deformation seam.
• The fastening is made directly to the formwork.
• Holes for fasteners are allowed to be made only in the extreme zone of the hydraulic gasket, behind the extreme anchor.
• The mounting pitch is 200-300 mm, symmetrically on both sides.
• Additional fastening is also performed 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.

The Protex ND 500/35 blue hydroshonk PROTEX is an indispensable tool for waterproofing and sealing movable joints in monolithic buildings, which includes foundations, underground parking lots, tunnels, canals and much more.

It is easily mounted on formwork sheets, providing reliable waterproofing in hydraulic structures such as reservoirs, canals, dams, pools, as well as for joints of foundations, foundations, tunnels and multi-level parking lots.

Made of high-quality plasticized PVC-P polyvinyl chloride, our Protex ND 500/35 hydraulic gasket is distinguished not only by its excellent tightness, but also by its ability to effectively perceive deformations of reinforced concrete structures without violating its functionality.

With its help, you can safely embed it into a concrete structure, and the ribs on the locking plane will not allow moisture to penetrate inside.

The use of our hydraulic gasket contributes to a reliable seal between two concrete structures and for particularly important projects it is recommended to use it in conjunction with an internal hydraulic gasket.

What is especially remarkable is that our Protex ND 500/35 hydraulic gasket easily withstands high water pressure both from the inside and outside, which makes it an ideal choice for structures with special requirements in ensuring tightness.

In addition, it is suitable for use in all types of structures.

Our hydraulic dowels are supplied in convenient rolls 20 meters long, providing enough material for your project.

The Protex ND 500/35 PROTEX PVC hydraulic gasket is an ideal solution for sealing and waterproofing movable joints in monolithic construction.

Due to its unique properties, it provides a reliable and impermeable connection between concrete structures.

The blue Protex hydraulic shutter has ribs on the locking plane, which prevent moisture from entering the structure.

Due to the deformable area, it easily adapts to deformations of reinforced concrete structures without breaking the tightness.

The use of an external Protex hydraulic gasket makes it possible to effectively seal between two concrete structures, providing reliable protection from moisture.

In the case of particularly important structures, it can be supplemented with an internal hydraulic gasket to increase tightness.

Our hydraulic gasket is ideal for all types of structures and can be used even in structures with special requirements to ensure tightness.

It can withstand high water pressure both inside and outside.

The Protex hydraulic shutter is supplied in rolls 20 meters long, which provides convenience during installation.

Do not miss the opportunity to use a reliable and airtight material for waterproofing your construction projects.
