Abstract (en)

[origin: DE19625209A1] The invention concerns an injection hose intended for sealing expansion joints in concrete structures. The hose is in the form a continuous hollow extrusion (12), made of elastic, flexible material, with a continuous longitudinal bore (10) and at least one longitudinal groove (16). The groove (16) is connected to the bore (10) by means of apertures (22) in the wall of the extrusion and is fitted with a sealing strip (24), made of compressible, elastic material, which extends over the apertures (22). Production of the hose is made particularly simple and inexpensive by virtue of the fact that the width of the groove openings (26) is less than the diameter of the sealing strip (24) and that the means for holding the sealing strip (24) in place are formed by making undercuts in the sides (30) of the groove (16).
