A water swellable flooding material is disposed between the first and second metallic shield tapes. A second braided metallic shield surrounds the second metallic shield tape, and a jacket surrounds the second braided metallic shield. In one preferred form of the invention, the water swellable flooding material includes at least one water swellable strand disposed between the first and second metallic shield tapes. More particularly, the water swellable strand may include a yarn having a coating of a water swellable hydrophilic material.
