Aqua Seal Hydrophilic Swellable Waterstop | Swellable Water Bar
Aqua Seal is made of high performance modified rubber strips. Interaction between water and hydrophilic groups which are part of the Aqua Seal molecular structure results in swelling of rubber strips. When in contact with water, Aqua Seal reacts and can swell upto 300% of its original dimension to form a compression seal.
