I am currently building a pond (still digging). I have large boulders that
go 2 ft below water and come 4 ft out of the water. Theyre about 10 ton or
so.
I would like to have the liner below the water line and glue it or silicone
it to the large boulders making it waterproof. I really dont want to show
the liner above the water and stacking stones on the liner and boulder would
be very difficult since it's almost vertical.
Has anyone come across this dilemma?? I see many pond pictures on the
internet with similar setups but they dont tell how the liner is hidden.

IF you can get a perfect seal of the liner to the boulder then you should be
able to have the liner anywhere below the boulder that you can fit it. The
problem is getting the perfect seal.... I take it you don't have the
equipment to put the boulders in on top of the liner...... DK

Another thought.... You can make ponds by using clay as your "liner". I do
not know how large your pond is going to be (sounds large if it is going to
have the boulders of this sized not overwhelm it..) or how costly this would
be ...

Clay Ponds

If your soil particle size is small (sandy, silty soils) with a clay content
of at least 10% then soil compaction is the easiest way of sealing the
bottom of your pond. Alternatively, soils with a clay content of more than
20% can be imported for compaction. Alternatively, bentonite clay can be
purchased.

Although clay lined ponds are the most natural looking, clay is not the best
choice of impermeable barriers for backyard ponds. The clay itself is very
heavy and can leak if not installed correctly. Bentonite clay is applied at
the rate of 1 to 3 pounds per square foot, tilled in, and then rolled to
compact the particles. Use a sprinkler to wet the bentonite before
compacting. Bentonite swells when wet but if complete drying occurs
bentonite shrinks and may compromise the seal. Add water immediately,
otherwise the clay will dry out and crack. If you empty the pool it must not
be allowed to dry out. A mixture of sand and earth is placed on top to
protect the water-resistant clay liner from mechanical damage.

Geotextile clay liner is a product that sandwiches bentonite clay between
two layers of felt. The felt is sewn so that the clay cannot move and
collect anywhere along the width or length of the roll. Geotextile clay
liners are generally used for large farm ponds, and are expensive.

Consult your bentonite supplier for alternative methods of application
(including adding bags of clay directly to the pond to achieve a water
barrier as the clay particles settle out on the pond bottom).

Ick. I'm pretty sure that your bond will be very hard to do. Maybe,
just maybe, hot tar painted around the granite in a 10" or so strip
would allow you to adhere the butyl to, but any movement in the liner
(and they do move) is going to push that joint very hard.

Other such effects, I think, are done by fitting the boulder after
it's been lined, or using clay puddling which will make a fairly good
seal as it expands. Concrete is a bugger to seal to stones
effectively, though it can be done; but not well enough to trust
completely. (Use PVA in the mix, pva on the granite, two coats of pva
once concrete has set, and then brush all over with cement slurry
(also with pva). I've done this and it works, but only in small
ponds.)

This is a true story. When I was a young boy, my family was living in
Wenatchee, WA in 1950 while my step-father was working as a construction
worker enlarging and rebuilding Rocky Reach dam on the Columbia River.

One evening he came home and said the Corps of Engineers had contracted
with river tugs to pull a succession of barges loaded with horse manure
to a position upstream of the dam. The horse manure was being shoveled
into the river, to disperse in the current and lodge against the
upstream face of the dam.

This particular dam is built of concrete spanning several natural rock
outcroppings, rock "islands" in the Columbia, for which a small
neighboring town was named (Rock Island, WA). Apparently there was a
problem with leakage between the concrete portions of the dam, and the
rock formations.

According to stepdad, as it was explained to him, horse manure contains
a high percentage of undigested fiber (as any country boy who has kicked
well-aged "horse biscuits" around the meadow knows) and this coarse
fiber would flow with the water into the leaks, lodge there and swell,
creating an effective natural seal.

Not that I'm suggesting this as a method for sealing between the liner
and the boulders, but then again, if some sort of "belt" could be fitted
to hold the butyl liner tightly to the boulder, then a good sealing
material between the liner and the rock might serve a good purpose.

Pass the biscuits?
