There is a tiny stream running through my lawn and the previous owner of
my house decided to turn it into a succession of six waterfalls and six
ponds. When I moved in water was gurgling over each fall, from pool to
pool, down the slope of the lawn. Two years later, however, only ONE
waterfall is working. All of the other five walls (mini-dams) which he
built out of small rocks and cement have developed leaks. Only one of
the ponds is currently full - and that's the one that is sending excess
water over the lip to fall into the next pond. But the rest of the
ponds are only almost full - their water is moving from pond to pond
through small holes in the walls. Each wall only has one or two
To dry up the stream in preparation for concreting repairs, by emptying
all the ponds, would be a back-breaking task, and anyway, diverting new
incoming water would be difficult.
So, is there some thick substance which I can ram into each hole and
which will then set solid, despite the pool of water on one side of
hole and the wet conditions on the other?
I have concrete, of course. And I believe one can get hold of
"plasticiser" to mix with it. But I am not sure if that's the solution
and if it is I'm not sure what proportions to mix it in.
Any ideas most gratefully received!
rubber roofing is about 1/8 in thick and cut to the size of the pool
bottom will water proof the bottom and allow the water to run over the
dam. rocks can then be put on this surface to hold it down and make
Buy a wax toilet ring. Cut it into small chunks and press the chunks
into the holes. The stuff is like VERY sticky putty, and will seal the
leaks. I keep a couple on board my boat in case I ever put a hole in
the bottom and need an instant patch. They are very inexpensive.
I don't know how big the holes are that are leaking but bentonite is
used in porus areas to help contain water. When it gets wet it swells,
closing off some of the portals. You might try that. No
When I had a similiar problem in a pond, I just dumped crusher run into
it to stop the leak. If a big hole, a couple of rocks first. Has
worked well for me. I have no confidence in concrete, water undermines
it too fast. If you have crayfish causing the problem, mix a bit of
rock salt into the crusher run, salt kills crayfish.

get some cheap, brown garbage bags, the real thin kind, and put them near
the holes. They should suck in with the water, and after a few you can plug
the holes with clay. It's temporary, but will last at least a few years.
If the bags come right out the other side, you need a better repair. I
fixed a leaky dam on a one acre pond this way, and it was good for several
years. Now it's too far gone and the dam needs replacement.

If you need the more permanent repair, it's easy enough to divert the stream
using a pump.
