How It Works
The FLEXVERSE® swellable bar is made of an engineered TPE hydrophilic compound added to a polymer or bentonite base. On contact with water, it expands uniformly at a controlled rate, sealing the construction joint against water ingress and creates a watertight system that remains potent even in the smallest penetrations.
Why It Lasts
When no longer in contact with water, the compound shrinks back, regaining 80–90% of its original size. Unlike single-use clay or rubber alternatives, the FLEXVERSE® TPE compound withstands repeated wet-dry cycles over the long term without losing its performance or integrity.

How Hydrophilic Swellable Water Bars Protect Construction Joints
Installed at concrete construction joints, hydrophilic swellable water bars expand on contact with water to help seal gaps and reduce water ingress in critical waterproofing zones.
