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 reinforcing 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 ND 240 PVC PROTEX blue hydraulic gasket is an indispensable assistant in sealing and waterproofing movable joints during construction.

It does not matter whether you are building buildings, foundations, tunnels or canals - this hydraulic gasket allows you to securely embed it into a concrete structure.

What makes this water cannon so unique?

Firstly, its locking plane has ribs that prevent moisture from entering the structure.

Thus, you can be sure of reliable tightness.

In addition, the presence of a deformable section allows this hydraulic gasket to perceive deformations of reinforced concrete structures without violating its tightness.

It also effectively seals between two concrete structures.

If you are working with particularly important structures where tightness is the main requirement, the ND 240 PVC hydraulic gasket can be supplemented with an internal hydraulic gasket.

This hydraulic shutter also withstands high water pressure both outside and inside.

Its reliability and applicability are suitable for all types of structures.

The ND 240 PVC hydraulic gasket is supplied in rolls 20 meters long.

The ND 240 PROTEX hydraulic gasket is the best solution for waterproofing and sealing movable joints in the construction of buildings and other structures.

This key provides reliable protection against moisture penetration into the structure and is mounted directly on the formwork sheet.

Made of plasticized PVC-p polyvinyl chloride, the ND 240 hydraulic gasket justifies its attractive quality and efficiency.

Its features include the presence of ribs on the locking plane, which prevent moisture penetration and allow the structure to be protected even in case of deformations.

The ND 240 hydraulic shingle is suitable for a variety of structures - from foundations to underground parking lots and tunnels.

It can be used in hydraulic structures, including reservoirs, canals and dams, and is designed for waterproofing foundations, multi-level parking lots and other important underground structures.

Our hydraulic gasket is complemented by an internal hydraulic gasket in particularly important structures to ensure complete tightness.

It is able to withstand high water pressure both from the outside and from the inside, which makes it suitable for all types of structures.

The advantages of our hydraulic shutter include its versatility and ease of installation.

We offer it in rolls, each of which has a length of 20 meters.

Do not hesitate - choose the ND 240 hydraulic gasket for your project to ensure reliable waterproofing and tightness of your structure.
