Protex Hydroshonk PO-3, bay 20 m:

• Ensure reliable waterproofing of expansion joints with the help of the Protex series PO-3 repair hydraulic tamper.
• This product is ideal for reliable sealing of joints between existing concrete structures and new poured elements.
• The PO-3 hydraulic gasket, made of plasticized PVC-p polyvinyl chloride, provides a strong and airtight fixation to concrete structures.
• Thanks to the unique P-shape and the use of an elastic sheet material such as styrofoam, you will be able to clearly install the hydraulic shutter in the desired position.
• The use of the Protex PO-3 repair hydraulic gasket is especially recommended for the construction of buildings, foundations, underground parking lots, tunnels, canals and other structures where reliable waterproofing and tightness of joints are important.
• We offer bays of 20 meters each, which provides enough material for your projects.
• If it is necessary to lengthen the hydraulic rod or create complex spatial transitions, you can weld it in a conductor, use a construction hair dryer, a flat heating element or simply glue the sections.
• Do not leave gaps in the waterproofing and ensure the reliability of your structures with the Protex PO-3 repair hydraulic gasket.

• The hydraulic rod is installed in the design position, so that the middle of the hydraulic rod is located in the center of the deformation seam, with a smooth side, without anchors, the repair hydraulic rod is glued to the surface of the existing railway structure.
• For gluing, it is recommended to use Innoelast adhesive sealant based on a silane-modified polymer.
• For reliable fixation of the hydraulic shutter, a metal strip made of stainless steel 50x5 mm or aluminum 60x6 mm is used, which is fixed from the inside of the hydraulic shutter using dowels.
• For complete sealing, the dowels are installed on a sealant - fill the hole for the dowel with sealant before installing the dowel.
• The installation pitch of the dowels is 150 – 300 mm, chosen depending on the strength of the reinforced concrete structure and the expected water pressure.
• The U-shaped shape allows you to clearly install the hydraulic key into the design position using an elastic sheet material, for example, a styrofoam plate, on which a key is "put on".
• The sheet itself is fixed to the formwork and reinforcement frame so that the operated area of the hydraulic gasket turns out, after pouring, to be on the same level with a clean floor or slightly lower.
• The anchors of the hydraulic rod are fixed to the reinforcement frame using special clamps or knitting wire in increments of 300-500 mm.
• 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 Innoellast.

How do I connect a hydraulic gasket?

If necessary, elongation and to perform spatial nodal transitions are welded in a conductor, with a construction dryer, flat TEN-ohms or glued together
