Bentonite-Based, Hydrophilic, Expandable, Flexible Rubber Waterstop Strip for Watertight Construction

Idrostop B25  is a waterstop used to produce watertight construction joints in civil, industrial and hydraulic construction. Idrostop B25 is composed of a mix of natural sodium bentonite and polymers that give the product exceptional properties of compactness, flexibility and stability. The material is produced according to a formula developed in MAPEI’s own research and development laboratories. Idrostop B25’s expanding process takes place in a controlled, gradual and uniform way without the risk of altering the balance of the mix.
