Abstract

A packer and a corresponding method for filling cracks in concrete structures with packing material pumped into the crack. The packer comprises a packer body (1) designed to be inserted into a hole (2) drilled in the structure to be repaired, said packer body having a part (8) with a conical outer surface and a seal (7) around the packer body; a fixing tube (13) which, when the packer is in the hole, protrudes out of the hole; and a check valve (6) in the packer body, located on the opposite side of the seal with respect to the fixing tube, which check valve opens into the hole and communicates with the outer end (4) of the fixing tube via a hole (5) going through the packer body and the fixing tube. According to the invention, the packer body and the fixing tube form a single, continuous cast integral body and the seal (7) consists of an elastic tube of constant circular cross section which can slide between and around the fixing tube and the conical part (8) of the packer body.
