Unlike conventional water stop, BentoSeal exerts perfect and permanent water stop even in the level of high ground water. The main material of BentoSeal is natural sodium bentonite swelling about 15~20 times its original volume when it absorbs water. Installation is very simple and fast.

Characteristics

1• 4S effect is displayed when it is hydrated with water in concrete but not able to swell free in confined state

2.*4S: Self-adhering to structure surface, Self-detailing corners, Self-seaming overlapped joints of bentonite sheets, and Self-sealing minor cracks of structures

3. Easy and fast to install in place

 Permanent water stop: natural inorganic mineral bentonite which is hardly degradable results in, no deterioration of its function

 Simple, fast, eco-friendly construction: installation simpler and faster than water stop based on rubber and synthetic resin

Use

• Water stop of horizontal or vertical construction joint for underground structure such as basement, cut and cover tunnel, parking lot, and water tank

• Water stop supplement at such horizontal or vertical penetrations as pipe, duct, and pile head of structure
