Water Stops

When using a recoverable anchor with a plastic or fiber concrete sleeve, we recommend using a cast Water Stop for a water and gas tight tie point. Water Stops are certified for watertightness up to 7 bar in accordance with DIN 1048. In order to seal the tie point even more easily and more securely, we recommend using a Water Stop Type N.
It consists of a cold rolled anchor bar with a welded-on metal plate and an optional bentonite sheet that is glued on.
