Bentonite - Digitalfire

Notes. Bentonites are classified according to several types (e.g. calcium, sodium, potassium) but in the ceramic industry sodium bentonite is the material of commerce (this is the same material used by the drilling industry). Sodium bentonites have incredibly small particle sizes (and thus surface areas). Combine this with the active particle surface chemistry (which makes them hold onto water ...

Water Well Diagram and Proper Well Construction

It is a good idea to add a layer of clay cuttings and bentonite (that have been removed during the drilling process) directly on top of the gravel pack. This will help seal the gravel pack and prevent the bentonite/cement slurry from penetrating downward into the gravel pack. The slurry is poured into the 50mm (2 inch) space around the well casing.

If you want to try another method, there is the option of using sodium bentonite clay. Sodium bentonite clay can be used to make a natural water sealant that will retain water in your pond. The appropriate amount is about two pounds of sodium bentonite per square foot of bare soil, or in other words use a 50 lb bag per 25 square feet.
