Hydrophilic WterStop DC2010

 INTRODUCTION


DC Seal has been developed for waterstop function in construction and civil engineering application , which Cause inevitable leaking all the time.

DC seal will be swelling in full range upon contact with water or moisture in terms of volume which performs
perfect water stop.

Bentonite WaterStop ( 25 X 19 , 20 X 15 )

 INTRODUCTION


Bentonite waterstop is preformed waterstop consists of sodium bentonite and
butyl rubber , and it swells 1,600% when contacts in water.
It is excellent in softness and stiffness at the same time , therefore widely used in joint area
both construction as well as civil work.


 CHARACTERISTIC


1.
 Due to material of natural bentonite , it shows outstanding expansion when in contact with water
2. Self-Sealing effective
3. Permanent water-tight function
4. Easy installing method
5. Safe handling in terms of material safe and hazardous
