KEMASWELL is black flexible hydrophilic strip made of natural sodium bentonite clay and synthetic rubber. Permanently active system, which swells up to approximately 400 % of its original dry volume. The expansive clay mass will thus seal hair line cracks and voids in the joint. Highly elastic and plastic properties will easily counterbalance the initial concrete shrinkage of the structure.
|Field of use||
For preparation of mortars, cement injection suspensions or concretes, where shrinking
has to be compensated. At the same time it reduces the amount of water, thus considerably
improving plasticity or pourability of mortars and concretes.
Increase of plasticity and flow ability of mortars
Contains no chlorides and hazardous admixtures
