TegoBloc TxSwell is a detailing accessory product for GMX’s Bentonite Waterproofing System used at the footing/wall junction to provide additional waterproofing protection. TxSwell 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 TegoBloc Swell products. Each TxSwell 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. The free swell rating of the bentonite is: two grams sifted into deionized water swells to occupy a minimum volume of 16 cc.
