The seal system (1) to fill a joint between two bodies, and especially concrete blocks, has an injection body (2) fitted to an outer surface (26) of the block, with an injection channel (12) to insert the sealing material. The channel has at least one opening at the joint side, and a covering hollow profile strip (3) within a valve seat channel (13), to prevent sealing material returning into the channel. The covering strip is of an elastic rubber material, structured to reduce its cross section on an injection pressure towards the joint, and allow the sealing material to flow through around its sides. |
