Steel packer

Steel packer serve for injecting materials via drill holes into structural elements, cracks/joints (e.g. injection, injection, sealing of expansion joints) or to the rear of structural elements (e.g. injection). The steel packer is placed and clamped in the drill hole. Clamping means, with the clamping mechanism the clamping rubber is compressed lengthwise until it obturates the drill hole so tightly that the filling material can be injected safely through the steel packer even at high injection pressures.
