Bentonite waterstops are invaluable to the concrete and construction industries, providing an efficient means for sealing construction joints. Bentobar+ has been sold worldwide for over 25 years and is well known for its stability and durability. Even after repeated wet-dry cycles, Bentobar+ maintains a perfect seal thanks to its high rubber content. Bentobar+ is also far less susceptible to washing out than traditional bentonite seals. In addition to the standard version, variants also exist for use in seawater (saline concentrations up to 3%) and contaminated water.
