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.

Hydraulic gasket ND 500/75 PVC PROTEX external for expansion joints blue, 20 m.p.,

Protex Hydraulic gasket ND 500/75 is specially designed for proper sealing and waterproofing of movable joints in monolithic construction of buildings. Thanks to it, you will be able to ensure reliable hermetic embedding in a concrete structure, prevent moisture from entering the structure by having ribs on the locking plane and perceive deformations of reinforced concrete structures without breaking the tightness.

The application of the Protex ND 500/75 Hydraulic spigot is not limited only to monolithic construction.

It can also be successfully used for sealing and waterproofing hydraulic structures such as reservoirs, canals, dams, pools and more.

In addition, it is suitable for waterproofing joints of foundations, foundations, tunnels and multi-level parking lots.

The Protex ND 500/75 hydraulic gasket is made of plasticized PVC-p polyvinyl chloride, which provides it with resistance to high water pressures both outside and inside.

It is also suitable for all types of structures, including particularly important ones, where special tightness is required.

The Protex ND 500/75 Hydroshonk is offered in convenient rolls of 20 meters long so that you can easily and efficiently carry out your project.

Choose the Protex Hydraulic gasket ND 500/75 and ensure maximum tightness and waterproofing of your construction!

Hydraulic gasket ND 500/75 PVC outer for expansion joints blue PROTEX, 20 m.p.:

Carry out monolithic construction of buildings with confidence in the tightness and waterproofing of movable joints, thanks to the reliable Protex Hydraulic Gasket ND 500/75!

Our product is used to close expansion joints in foundations, underground parking lots, tunnels, canals and other structures.

Thanks to the installation of a hydraulic shutter directly on the formwork sheet, we provide effective waterproofing of monolithic construction sites. The advantages of the Protex ND 500/75 Hydraulic shutter include the presence of ribs on the locking plane, which prevent moisture from entering the structure, and a deformable area capable of perceiving deformations of reinforced concrete structures without breaking the tightness.

Our hydraulic gasket can also be used to seal between two concrete structures and important structures are complemented by an internal hydraulic gasket.

It is ideal for structures with special requirements for tightness and withstands high water pressure both outside and inside.

The Protex ND 500/75 hydraulic gasket is perfectly suitable for all types of structures and comes in convenient rolls with a length of 20 m.p.

Purchase our product and be sure of reliable tightness and waterproofing of your construction site!
