Packers for injection molding 13x100 mm, Kharkiv region.

Packers, specialized devices, are used in waterproofing works, for injecting gels, polyurethane and epoxy resins, cement suspensions into working and deformation seams and cracks in structures made of concrete, brick and natural stone. For waterproofing, reinforced concrete and other concrete are used. constructions use injection packers made of steel or aluminum. Depending on the injection materials used and the goals of the work, packers can be of different lengths, diameters and types of connecting fittings. The difference between a collet and a flat fitting is in the method of attaching the coupling. To prevent leakage of the injection composition, the packer is equipped with a return valve.
when carrying out repair work related to the waterproofing of concrete and brick structures and constructed, for example, when repairing cracks, sealing deformation joints, stopping leaks and filling voids(//tractor-service.com)
Injection of structures is carried out through installed injection packers. The device of the mechanical packer securely fastens the ego in the surface during twisting. And the presence of a non-return valve prevents the injection material from flowing back.
Steel packers are used for injection of polymeric materials during the repair of waterproofing.
