I'm about to install a pond and have heard that some people use a special fabric layer on the soil, before they put the liner down. Apparently it stops little stones sticking through. I just happen to have a load of oold carpet and the underlay that I have taken out of the house when a wooden flor was layed. I was wondering whether this would be ok. I could put down both the carpet and the underlay for extra cushioning. What I need to know is would the carpet begin to smell once it got damp. The last thing I want to do is have a terrinble smell coming from around the pond once it is all fitted and then the nightmare of having to get it all out.

Use your old underlay if you want it will be fine, or put a bed of sand down. You can use the carpet it will be o.k. but i think the underlay or sand is better.

There is a reason people use proper underlay or sand i shall explain.
carpet is free (otherwise you wouldn't be using it)
underlay or sand costs money
the idea is to stop stones puncturing the liner sand does this by simply covering them up, its why you uses a 2 inch layer
proper underlay does it by stopping the stones coming through
carpet or old newspapers (i have seen it done) will rot overtime this then lets the stones through because as it rots it gives less support and the weight of the water pushing down means that any stones will soon puncture the liner.
its your choice but if you want to do it right and not change or repair the liner in years to come use the right protection.
it costs more initally, but lasts a lifetime

breezer, to be fair, i would only expect any pond liner to last a maximum of 20 years. After this i would expect to replace it pretty soon.
And we lined ours with sand. on emptying it 2 years after, all the sand had collapsed, forming bulges near the bottom corners. Couldn't do anything - theres 2 courses of wall on top of the liner.

you can get liners that are g'teed for 30 years now, sorry about your sand, but carpets wont even last 2 years, and it may be the sand moved as you lifted the liner
but carpet is just asking for trouble
