WPM® Crack Inducer profiles are meant to control and waterproof underground cast-in-place concrete structures shrinkage cracks.

In an integral waterproofing system, it is crucial to control shrinkage cracks when casting slabs over 10m long. When casting a 25m long wall all at once, crystalline admixture alone is not able to self-heal those shrinkage cracks because they are usually bigger than 0.4mm.

This is where the WPM® Crack Inducer profile comes into play, by making crack inducer the weakest part of the concrete, it will gather the area's shrinkage cracks in one place and make it waterproof while maintaining the structure's strength.
