How big is the pond? This would help to determine the best way to puddle
the clay. Puddled clay is quite durable as long as you don't let it dry
out, which in turn would cause the clay to crack. There are various
factors that need to be taken into account with this type of pond ie the
water feed to the pond. Is this going to be a natural source or another
type of source? Let me know and I will try to help you further.

Thanks Nick
Im anticipating maybe 15 feet by 10 feet ish. It will be artificially fed
(ie hose pipe), maybe some kind of auto top up, if I can figure it out.

It was the only option before concrete and liners, and since then
isn't much used.

It /can/ work well, apparently, but only if the ground is naturally
wet all the time anyway - ie, a low lying boggy area with a stream.
And if the water level drops then the clay dries out where it's
exposed and cracks.

Lot of work too, which is why most are done with liners these days.

One way round might be to line the pond edges with sacking so that it acts
as a wick and keeps the exposed area damp. Presumably it would need more
frequent topping up with such a system. However, deep rooted water plants
will eventually break through the puddled clay anyway and cause leaks. We
have a smallish pond in our boggy bit and are happy enough for it to be
periodically dry (we have other lined ponds) and eventually fill up with
irises.

The cracking problem is really only a problem when clay is imported to form
a liner over permeable soils. I suspect that on solid clay the drying out
and leaking problem would be less significant.

Have a look in the books by Anthony archer wills, THE name in large scale
water features.

Auto top up can be achieved as with capillary beds with the use of a
ball cock, in this case within a small tank sunk into the ground.

Not true. Canals are usually built higher than the surrounding land to
prevent flooding.

And if the water level drops then the clay dries out where it's
exposed and cracks.

If it is thick enough then it takes a good while to dry out. Canals have
breeches, but as long as they are fixed within a few days the puddle is
not damaged.

Lot of work too, which is why most are done with liners these days.

You do it in your bare feet, and get all the local kids involved. Don't
put the red carpet out though!

An artificially fed, puddled clay pond of this size could prove to be
quite a headache in the summer when the water level drops due to
evaporation. The parts of the bank left exposed will have a tendency to
dry out and become cracked, which in turn will ruin the hard work that you
put in to puddle the clay in the first place. With a pond of this size it
may be better to use some form of liner. Also, with a pond of this size,
using puddled clay, if either fish or water fowl come into the equation
then you will nearly always have cloudy water to contend with. I know that
this can still be a problem with a liner, but it is alot worse using
puddled clay.
With regards to how you go about getting the clay puddled in the first
place, the way that I usually use is to hire a minidigger for a day (the
type with caterpillar tracks) and spend a day driving the thing over the
wet clay. It works a treat but this has always been on much larger ponds
where you have the room to manouvre the thing, and get the thing out
easily at the end of the day. I have this vision of a 10x15 feet pond with
a minidigger as a permanent central feature :-) It's different I suppose,
and looking at the recent entries at Chelsea may even make gold! ;-)
I would seriously consider using some form of liner. It will be easier to
maintain in the long run, and will allow you to enjoy your pond to the
full. At the end of the day that is what horticulture is all about. FUN!
I hope this is of some help.

According to some (not all) of the books I've read about ponding,
using normal liners in saturated ground is a bad idea, and say the
liner will rise to the surface.

Personally I've got my doubts about that, given the weight of water
above it, and that the water is the same density above or below the
liner.

You're probably right, but even natural clay what has lived there for
millenia does dry out quite easily if allowed to. My old garden was
built on one of the largest ball-clay sites in Devon (Liverton
Coldeast estate for the locals) and with the obligatory new estate's
1" of grubby topsoil we had slimy soil in the winter and dust in the
summer. Just being clay doesn't automatically mean permanent wetness.

And now I've got a garden built over an old lead mine.

P Have a look in the books by Anthony archer wills, THE name
P in large scale water features.

Thanks, will keep an eye open.

Doing quite nicely with mine now, top pond (4' square, block) now
faced with granite, slate waterfall and 2nd small pond below all done.
To do: Line and fill big pond (5M x 15M), fit bubble fountain at top
point (12' lift), a 1/4 scale granite leat into top pond. Then a
series of ponds or slow stream from there to the big pond again.

The liner was supposed to be delivered today, but no way a lorry's
going to get up our road - needed my snowchains on to get the car up
just now.

A friend has a very, very large pond in her garden, ( about 80' x 60')
built in the wettest part with trees all round so shaded, they hired a
digger and flattened the surface with the bucket part thumped up and
down, all over before allowing it to fill naturally. Seems to have
worked for the last eight years

JR Not true. Canals are usually built higher than the

But supplied with flowing water, and a certain amount of leakage is a
given and factored into the design when built, and the scale of
building is somewhat more than a garden pond. There's also a
considerable amount of effort gone into keeping the level exactly so.

But not many canals being built these days, so difficult to say
whether a modern material would be used in preference.

JOOI, do you know if anyone's done any costings on whether imported
clay works out cheaper than, for example, butyl (4ukp per square
metre)?

Lot of work too, which is why most are done with liners

Liners will rise in a pond due to the decomposition of organic matter
below the liner. As long as any organic matter (ie dead leaves etc) are
removed prior to the laying down of the liner, then it shouldn't fill with
gas and rise.
