Grout Composition 20% and 30%
Tundra carries granular bentonite grouting composition from 20% to 30% yield.
​
Our granular bentonite grouting composition contains high-swelling sodium montmorillonite clay. It is designed for use in water wells and monitoring wells, for sealing the annular space around well casing, and for plugging drilled holes and abandoned wells. The composition contains no organic additives or polymers.
​
This one-sack formulation of bentonite grouting composition mixes with freshwater to yield a pump-able grouting slurry with an extended working time. When set up, the grout develops a satisfactory seal with adequate structural strength and low-hydraulic conductivity.
​
When properly placed the grouting composition remains flexible, rehydratable and unstratified through heating and cooling cycles.
