Product Data Sheet


Description

Detailing accessory product for CETCO Waterproofing Systems used at the footing/wall junction to provide additional waterproofing protection. They consist of a thin, watersoluble 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 measures 2” (50 mm) in diameter by 2’ (0.61 m), assuring a consistent application of sodium bentonite at the critical footing/wall junction. Mineralogical composition of the sodium bentonite is a minimum 90% Montmorillonite with a maximum 10% native sediments and unaltered volcanic ash. Typical sieve analysis is 90% through a 20 mesh sieve and 10% through a 200 mesh sieve. Free swell rating of the bentonite is: two grams sifted into deionized water swells to occupy a minimum volume of 16 cc.

Applications

HYDROBAR TUBES are designed to work in conjunction with VOLCLAY waterproofing membranes at the footing/wall junction of foundation walls. They are a convenient method of providing additional waterproofing protection at this critical junction. They are not an expansion joint sealant.

Packaging

HYDROBAR TUBES are packaged 16 tubes per carton; 32 linear feet (9.8m) per carton. Carton weight 50 lbs. (22.6 Kg). 50 cartons per pallet.
