Kryton Crack Inducing Waterstop

Product Code: K-341

DescriptionKryton Crack Inducing Waterstop

Kryton Crack Inducing Waterstop is specially engineered to produce a waterproof crack control joint.

Used as part of the Krystol Waterstop System and in conjunction with Krystol Waterstop Grout, Kryton Crack Inducing Waterstop is resistant to waterborne chemicals and is perfect for blindside applications where access is limited. It is placed in a predetermined location to isolate cracking to a controlled area in order to eliminate water entry through uncontrolled shrinkage cracking.

Kryton Crack Inducing Waterstop is fastened to the concrete form or shoring wall. A keyway is measured and formed directly opposite the waterstop. After the concrete is placed, a controlled crack develops from the Crack Inducing Waterstop through to the keyway. Krystol Waterstop Grout is then tightly packed in the keyway for added protection.
