KingSwell 2010 is made of bentonite free high performance polymer modified chloroprene rubber strips. The swelling action is the result between water (fresh or saline) and hydrophilic groups which are part of the KingSwell 2010 molecular structure.
Advantages
Active protection- KingSwell 2010 hydrophilic waterstop swells in contact with both fresh water and saline (sea) water to form an affective compression joint
Slow expansion rate to prevent damage to freshly placed concrete during curing
Retains original shape after repeated and contraction
