FleeceproofX® 1 is used to create a waterproof seal between two concrete sections.
The internal, coated metal waterstop features a one-sided fleece coating that mechanically bonds itself to the fresh concrete during the curing process and its polymer layer swells on contact with moisture. As a result, a double action waterproofing effect takes place against pressurised water in the construction joint or in the crack-control joint.
The effect of the fresh concrete bond and the pressure resulting from swelling prevent water tracking under or around the interior metal waterstop system. Hence it is perfectly sufficient when installing the waterstop in a floor/wall construction joint to secure it to the upper part of the rebars (minimum embedment depth in first concrete section: 3 cm). A time consuming kicker is not necessary.
