The ND-R 320 hydraulic gasket is an ideal solution for waterproofing expansion joints when mating with concrete and metal structures. This product is necessary in the monolithic construction of buildings, foundations, underground parking lots, tunnels, canals and other facilities. Our hydraulic gasket is easily fixed to the existing structure, and the free part is loosened to the reinforcing frame before pouring concrete. The material of manufacture is thermoplastic elastomer or plasticized PVC polyvinyl chloride. The advantages of using our water slide include: - Sealing of deformation joints between the finished structure and the poured concrete structure - Reliable fixation with a metal strip fixed outside the hydraulic joint - Elasticity of the material, allowing the hydraulic joint to be installed in the correct position - Ribs on the locking surface and anchors, preventing moisture penetration into the structure - Applicability in the locations of deformation joints of monolithic reinforced concrete structures - Important structures can be supplemented with the help of a U-shaped repair hydraulic shutter of the PO series, the PROTEX hydraulic shutter ND-R 320 is offered in rolls with a length of 20 meters. Trust in the reliability and quality of our products!

The ND-R 320 hydraulic gasket is an ideal solution for sealing expansion joints between existing concrete and metal structures. Our product guarantees reliable protection against moisture penetration and ensures perfect fixation to the design position due to its elasticity. The locking plane with ribs and anchors optimally prevent moisture from entering the structure. The ND-R 320 hydraulic gasket is ideal for locations of expansion joints in buildings, foundations, underground parking lots, tunnels, canals and much more. They are produced in rolls with a length of 20 meters. Ensure reliable waterproofing of your structures with our excellent ND-R 320 hydraulic gasket.

How do I install a hydraulic shutter?

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 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
silane modified polymer Innoellast.

The ND-R 320 hydraulic gasket is an ideal choice for reliable waterproofing of expansion joints when mating with concrete and metal structures. Our products are used in various areas of monolithic construction, including foundations, underground parking lots, tunnels, canals and more. In order to ensure reliability and durability, the hydraulic gasket is fixed to the existing structure, and the free part is installed on the reinforcement frame before pouring concrete. The main material used in production is high–quality thermoplastic elastomer TRE or plasticized PVC-p polyvinyl chloride. This ensures elasticity and allows you to accurately install the hydraulic shutter in the design position. We pay special attention to the details – our hydraulic shutters have ribs on the locking plane and anchors that prevent moisture from entering the structure. The ND-R 320 hydraulic gasket is widely used in the locations of deformation joints of monolithic reinforced concrete structures. And for particularly important objects, we recommend the additional use of a U-shaped repair hydraulic rod from the SOFTWARE series. The Protex hydroshpons are supplied in rolls 20 meters long to provide long-lasting protection and ease of use. Choose the ND-R 320 hydraulic gasket and trust in the reliability and unsurpassed quality of Protex products!
