Bentonite as a Clay Liner Seal
Bentonite as a Clay Liner Seal
(OP)
Hello,
We are working on a project which involves installing piles inside a tank compound. The compound has a clay liner as a floor and it has a berm all the way around. Since we'll install piles we'll break the liner and so I would like to seal the area around the piles. On a previous project an engineer specified sodium bentonite. However, the sodium bentonite ended up being very slippery and a trip hazard. Can anyone please give me some help as to what kind of bentonite we should use? Is sodium bentonite too vague of a term?
Thank y ou

The key to successful, non-messy use of either the mats or the soil/bentonite mix is to contain the product between two layers of properly compacted soil. Mats or mix are placed on compacted soil. Then compacted soil, with a total thickness of at least 12", is placed on top. Without this containment, bentonite swells uncontrolled, losing the low permeability that is essential for it to be an effective liner. A side benefit... there is no slime or mess to deal with.

You get the stuff at a large plumbing supply house, but using the term bentonite may confuse the clerk. A more common term is "driller's mud",vol clay, or some fancy trade name. Ypu do not want granulated type, sine it won't mix well. If considering adding a cover of "soil", why not just do the whole zone with the mix? Bentonite is cheap.

Bentomat was the product I was thinking about... I've used it on numerous pond liners... thanks, Dik
