Hydrobar Tubes are a detailing accessory product for Cetco Waterproofing Systems used at the footing/wall junction to provide additional waterproofing protection. It consists of a thin, water-soluble tubing filled with granular sodium bentonite. When wetted, the tubing dissolves, allowing the bentonite to hydrate and form into a dense, low permeable material that combines with the sodium bentonite in the Volclay System products. Each Hydrobar Tube assures a consistent application of sodium bentonite at the critical footing/wall junction.
