    Synthetic swell strip

    SPETEC® SST500 hydrophilic swelling tapes or waterstops are easily fastened to the concrete surface of an existing joint or where the joint will occur.

    Fixation can be done using SPETEC® WT400 glue or by nailing.

    In contact with water in a confined space, SPETEC® SST500 will swell and stop infiltration. The swelling capacity of the tire is more than 500%.

    SST500 performs consistently throughout its life cycle and its flexibility allows it to fill voids and cracks in the immediate area.
