Hi everyone
I've just excavated a pond (about 12 by 7 feet), and have 3/4 filled it with
water ( a mixture of 'old' water from an established pond with tap water,
about 50/50).I though this way I would be able to transfer the fish from the
old pond quickly to the new (I've also added tap water to the old pond to
restore the water level).
My problem now is laying paving slabs on the exposed liner around the edge
of the pond. I've read several books and articles about pond construction,
and they all say, "lay edging slabs or pebbles or rocks on a mortar base. Is
it really just a case of putting a bed of mortar about an inch thick
directly on the liner, and putting the slab onto the mortar?
I've no idea how much mortar to make (I estimate the pond has a
circumference of about 35 linear feet)

I've bought several bags of cement (25kg each), and have about 5 bags of
soft sand (40kg each).
The mortar would I think be made from 1 bag of cement + 3 bags of sand (plus
plasticiser), but how many slabs would this lay??

Any advice would be most welcome to a first timer!

Thanks.
