Crack Inducer profiles

WPM® Crack Inducer – Patented part of the White Tank Solution for underground construction.

The patented WPM® Crack Inducing Waterstop profile is designed to control concrete shrinkage cracks and ensure watertightness in reinforced concrete structures. Used with WPM® metal sheet waterstops and crystalline admixtures, it forms a complete white tank waterproofing system.

The profile creates a controlled, keyway-shaped crack with a perforated, polymer-coated steel sheet that seals the crack and maintains structural strength—ideal for load-bearing elements.
