Rubber Sealing StripUpon contact with water, it expands and deforms 2-3 times, filling all irregular surfaces, cavities, and gaps in the seams.

Generate tremendous contact pressure to prevent leakage. When joints or construction joints shift, causing gaps to exceed the material's elastic range.

At that time, the ordinary rubber waterstop material loses its water-blocking function. However, this material can also be used to stop water by absorbing and expanding when it encounters water.

Expanding rubber as a leak-proof sealing and water-stopping material not only saves on quantity but also can prevent excessive compression from causing deformation in general elastic materials.

The characteristics of the sexual fatigue enhance the reliability of the waterproof effect.
