Choose ND 320/35 PVC hydraulic gasket for reliable sealing and waterproofing of your construction projects.
How do I install a hydraulic shutter?
ND 320/35 PVC external hydraulic gasket for PROTEX expansion joints is blue, 20 meters long, designed for sealing and waterproofing movable joints in the construction of buildings, foundations, parking lots, tunnels, canals and other structures. Due to the possibility of reliable embedding into the concrete structure and the presence of ribs on the locking plane, our hydraulic shutter prevents moisture from entering the structure. Its deformable section allows you to perceive deformations of reinforced concrete structures without breaking the tightness. It can also be used for sealing between two concrete structures and supplemented with an internal hydraulic gasket in particularly important cases. Our hydraulic gasket is suitable for all types of structures and can be used in structures with special requirements to ensure tightness. It can withstand high water pressure both inside and outside. The product comes in rolls 20 meters long and is ready to help you ensure reliable waterproofing in your construction project.
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 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
silane modified polymer Innoellast.
