Cetco Voltex Sodium Bentonite Granules – 20kg

Granular sodium bentonite. 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 permeability ‘paste’ material that combines with the sodium bentonite in the waterproofing products to form a seamless waterproofing membrane. 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. 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. 

Limitations: 

WATERSTOPPAGE should not be applied in standing water or during precipitation. WATERSTOPPAGE is intended for below ground waterproofing applications. Product requires proper confinement. Confining soils should be compacted to a minimum 85% Modified Proctor density. 

Packaging: 

WATERSTOPPAGE is packaged in 25 kg bags; 40 bags per pallet. Yield per 25 bag is approximately 26 litres.
