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 . . .

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
