Hydrosponge VD 320, bay 20 m for sealing and waterproofing movable seams during monolithic construction of buildings, be it foundations, underground parking lots, tunnels or canals. With the hydraulic key ВD 320 from Protex, you will get the perfect solution to eliminate the harmful penetration of moisture inside the structure. The presence of ribs on the closing plane significantly increases its efficiency and provides reliable protection against the penetration of moisture into the structure. Moreover, due to the deformable area, it is able to perceive the deformations of reinforced concrete structures without breaking the tightness. The use of the VD 320 hydraulic key is particularly effective when sealing between two concrete structures. And in particularly important structures, it is perfectly complemented by an internal hydraulic key. Hydro-shponka can be used even in structures with special requirements to ensure tightness. Hydro-shponka VD 320 withstands enormous water pressure both inside and outside. Due to this, it is suitable for all types of structures without exception. Hydro-shponka is supplied in rolls 20 m long, which makes it even more convenient and practical to use. Do not miss the opportunity to ensure reliable tightness and waterproofing of your structure. Note: the hydraulic plug is made of plasticized polyvinyl chloride PVC-p.

How to install a hydraulic key?

The hydraulic dowel is installed in the design position so that the middle of the hydraulic dowel is in the center of the intended seam.
Fastening is carried out directly to the formwork. Holes for fastening are allowed to be made only in the extreme zone of the hydraulic dowel, behind the extreme anchor. The fastening step is 200-300 mm, symmetrically on both sides. Additional fastening is carried out in the same way to the reinforcing frame with a knitting wire. The spigot is connected by welding, by heating the ends of the spigot in a special conductor (for each spigot – an individual conductor) or with the help of an industrial hair dryer or a flat Ten. The temperature of adhesion is about 200 ° C (chosen experimentally). To connect the keys by the "cold" method, glue is used, for example, a one-component pasty glue based on
silane-modified Innoellast polymer.

VD 320 hydraulic seal is an ideal solution for sealing and waterproofing movable joints during monolithic construction of buildings, including foundations, underground parking lots, tunnels, canals and much more. With the help of our hydroshponka, you can reliably attach it to the concrete structure, preventing the penetration of moisture inside. Ribs on the closing plane create a reliable barrier to moisture, ensuring the durability of your structure. The unique deformable section of our hydraulic key allows it to perceive deformations of reinforced concrete structures without breaking the tightness. It is also used for sealing between two concrete structures, guaranteeing complete tightness. Protex Hydroshponka VD 320 can be used in structures with special requirements to ensure tightness, as well as in particularly important objects, supplemented by an internal hydroshponka. Our hydraulic dowels withstand high internal and external water pressure, making them suitable for all types of structures. Moreover, they are supplied in rolls of 25 meters, providing you with convenience and saving time during installation. Choose Protex Hydroshponka VD 320 and get a reliable, durable and hermetic waterproofing for your construction projects.
