Cetco Waterstoppage - Granular sodium bentonite

 

DESCRIPTION

Waterstoppage is chemically treated, granular sodium bentonite used as a detailing accessory product for CETCO Waterproofing Systems. When wetted, Waterstoppage forms into a dense, low permeable material that combines with the sodium bentonite in the waterproofing products to form a seamless waterproofing membrane. Mineralogical composition of Waterstoppage 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 Waterstoppage is: two grams sifted into deionized water swells to occupy a minimum volume of 16 cc.

APPLICATIONS

Waterstoppage is used to fill cavities and voids in the substrate prior to installing the main bentonite waterproofing course. It is also used to seal around slab penetrations to form a continuous waterproofing system. A fillet of Waterstoppage can be poured at the footing/wall junction to provide additional waterproofing protection. A 1/8” (3 mm) thick layer of Waterstoppage is also applied to the top of tunnels and earth-covered roofs prior to the main waterproofing material course. Waterstoppage is not an expansion joint sealant.

PACKAGING

Waterstoppage is packaged in 50 lb. (22.6 kg) bags; 40 bags per pallet. One bag equals approximately 0.83 cubic feet.
