Clay pond help please
I've recently scooped out an old silted up pond in my garden which filled up
and overflowed every winter but dried out in the summer. It's a fairly large triangle of about 20 yards each side. It takes four days to fill with a hose and then two days to drain. The clay base (of unknown thickness) seems watertight, but I reckon it's leeching out where the clay meets the topsoil sides. What are my options? It's a bit big for a liner but I understand that the clay could be extended up the sides. What is the technique for doing this? How thick does the layer of clay need to be? How do I test that the clay to be used is up to the job? Many thanks in anticipation |

Many thanks in anticipation Don't go there, believe me, It will do your head in, however thick the clay, as the wind and sun evaporate the surface water, the clay will dry out, contract,and send cracks down the banking. I landed up bringing the bull dozer in, plenty of hardcore and then laced with heavy chicken wire, followed by concrete, not cheap! but I have never bothered since, It's called piece of mind. |

If the pond is completely draining there's a hole at the bottom or the water
is making it through the clay. Does the clay go up the sides or is it only on the bottom? "Nicholas Walker" wrote in message ...

Do some internet searching for something to put in the pond to slow the
leaks down. Maybe there is a clay or something that will suspend itself in the water and clog the cracks up as it runs out the hole, "Nicholas Walker" wrote in message ...

The clay that is used is called bentonite or montmorillonite. It can be
dumped into the water to make a muddy mess, and some will settle out to the bottom, but if there are any leaks, the leaking water will carry the clay to the leak and plug it. Our Botanical gardens used it on a pond that they put in and I think it took about 2 years for the water to clear, and then if you have koi, they will root around in the clay and it will never clear. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Mickey" wrote in message ...

What some people think are clay ponds, are actually gravel pits,as in most quarries. |

You should have watched Gardeners World BBC2 on Friday. they constructed
huge clay pond the salient fact being that the clay must be at least 18 inches thick and must be tamped down preferably by machine and once filled will need to be topped up two days later as the clay will absorb the water necessary to make it watertight. I am only passing on what I have heard. -- Miss Pent remove the sword before replying "Tumbleweed" wrote in message . .. | "Nicholas Walker" wrote in message | ... | I've recently scooped out an old silted up pond in my garden which filled | up | and overflowed every winter but dried out in the summer.
