Description of Water swelling strip The bentonite strip is a green flexible hydrophilic strip of approx. 25 x 20 mm, made of natural sodium bentonite clay and synthetic rubber. The bentonite strip comes in lengths of approx. 5 meters. Due to shrinkage of the drying concrete, small cracks and voids will appear in the construction and cold joints, through which water can penetrate. In contact with water the green bentonite strip will swell approximately 400 % of its original dry volume. The expansive clay mass will seal the cracks and small voids in the joint. The first expansion is delayed to prevent the strip from expanding to soon in contact with rainwater during the installation. Advantages of Water swelling strip: 1. It can resist hydrostatic pressures of up to 80 meters of water column= 8 bar 2. The durability and performance of the bentonite water-stop will exceed the design life of the structure (bentonite is a product of nature) 3. The highly elastic and plastic properties of bentonite water-stop will easily counterbalance the initial concrete shrinkage of the structure. 4. Can fill small honeycombs 5. Will not dissolve in water and is non-polluting
