Stepping stones and plastic liners --query
Hi,
I'm digging my pond with a view to having stepping stones across as an entrance to my house. Can anyone advise me as to the best method to mount stepping stones given that they will of necessity be resting on a plinth which will obviously then be sitting on the plastic liner. I don't envisage a column of tanks rolling across it but clearly people will be stepping on the stones putting pressure on the liner. I had thought to place several layers of scrap liner beneath the plinth as a buffer but would really like some practical ideas. Thanks Mal |

Do not pinch the liner or folds in the liner. Do not place stones such that a sharp corner, when pressure will poke directly into liner. A small extra piece of liner cut to the same shape as the stone but slightly bigger would provide some protection and would be barely noticeable. My liner is EPDM and quite frankly I have not been kind to it during the construction phase and it is holding up very well. BV. |

I just checked my bookmarks for a pond that had stepping stones across it,
and I can't find it. However, what they did was to plan where the stepping stones would be, and poured "footers" beneath the liner, where the pillars for the stones would be. The footers were extra padded before the liner was put down, then more padding was placed under the block column(s). A cap stone was cemented to the top of the column(s). When it was all said and done, you could step right across the pond. Thinking about this description, it would seem that the columns would be unstable, subject to teetering. . . .. perhaps there was rebar placed in the footer, extending up through the column for stability? The liner could have been cut to allow the rebar to pass through, and then sealed . . . At any rate, it *can* be done . . . Lee "Kayakkhan" wrote in message . ..

Thanks Mal I am not completey sure i understand the question but here, i found this. http://waterfeatures.tripod.com/bridgesandsteps.htm Stepping-Stones Stepping-stones are a convenient way to cross a pond or stream, but are not as visually obtrusive as a bridge. They can either lead all the way across the pond, or simply a few feet out into it for observing or feeding fish. For formal ponds, you can use square or rectangular cast-concrete stepping-stones or slabs, large quarry tiles or similar geometric masonary units. Usually these are suported by piers of mortared brick or concrete blocks. For informalponds, you might use irregularly shaped flat rocks or flagstone, placed in a random pattern. If the pond is shallow enough, you might be able to use large rocks or stone slabs set directly in the pond. Otherwise, build up a layer of mortared flat rocks, or construct piers of poured concrete, brick or block to support the stones. Stepping-stones usually look best if staggered in a zig-zag or random pattern across the pond, rather than in a straight line. Place the stones close enough together so that people can walk without hopping, and make sure the stones are large enough to provide a stble footing. The surface of the stones should be high enough above the water so that they stay dry. This will help keep algae and moss from growing on the surface of the stones, which could make the stones slippery. |

I did a stepping stone in the middle of our frog pond, I first set a paving
stone as a footing for the piller in my case three foot high, I then placed pond underlay over the paving stone making sure their were no stones however small on the stone then the liner was installed on top of this a spare piece of liner was laid quite a bit larger than the piller, I then constructed the piller on the spare liner the piller started 16inch sq then reduced half way up to 8inch sq upon this i then set the stepping stone once the piller was dry I gave it two weeks I then sealed the piller with pond sealer. The piller etc has now been in place 18months and you can no longer see the piller below the stepping stone. Hope this is helpful. Jon "Kayakkhan" wrote in message . ..

Make the base of the stones as wide as possible to distribute the load.
