Info about Volclay granular sodium bentonite???

Yes it can...is the leak large or just a seep? If its a seep you maya
be better off with a powder form if the water is not too deep......If
you know where the leak is at, or at least a half a$$ed idea granular
or pelleted form would work better in deeper water.......

Once you appy it, it may take a couple or three days until it stops it
up. Sometimes having a decent flow is better than a seep when usiing
bentonite, as it pulls it into place better, than a seep does. I just
fixed a seep on my spillway and also hade my entire pond relined with
sodium bentonite......

Do you have a source for it? You can get granular or Pellet form from
CETCO.......its product number Volclay CG-50 This is perhaps the best
stuff to use overall.....about $10.00 per 50# bag

Depending on your soil type the application rate will vary.
Normally sandy soils you would apply it at 8 to 10 pounds sq ft/
Silty soils 4 to 8 lbs per sq ft and clay is 2 to 4 pounds per sq ft.

The CG-50 is granular in composition. There is a CP-200 which is
powdered and CC-8 which is a crumble form.
Powderd type is harder to work with as it floats and blows n the
slightest breeze, but if you make a barrier to contain it when you
want it to sink it works fine.......

CETCO phone number is 1-847-818-7965
Ask for Joe Marzullo and have him send you an info pack and he can
also provide a source in your area for any of these products.......

A pond is much easier to seal if it is drained and allowed to dry,
apply the bentonite and work it according to specifications of the
type you use, and then it needs to be compacted and kept damp and then
filled imediately so it does not dry and crack. Repairing a pond which
can not be drained is much harder to do, especially if you do not have
a clue where the leak is at, but it is still doable.been there done
that already on my pond as well as others.

Another method to use is the powder form, make a slurry in a drum, and
use a bucket to pour it into place. That way it will not float and
you do not need a floating barrier to retain it over the leaking area.
It will sink right to the bottom and start working to plug up the
leak..

They also have large blocks of dye in solid form, that can be
suspended from a float and you can watch the current flow to help pin
point the leak as well......CETCO has a source for these dye blocks as
well. About 4 or 5 bucks each

Lots of luck
