Breeze blocks????????? I have no idea what they are. Concrete blocks
(8x8x16) three high with steel rebar yes,but you should drill into the old
slab because it won't bond. Also a 6 inch cove sand around the inside
before the liner goes in would support some of the weight.
That would be my plan, Hank

Hello all,

I tried to download the latest 3000 messages to enable me to lurk a bit,
but not many turned up, so here I go:

We have an ugly area of solid concrete in our back garden which used to
be the base of dog kennels and runs. We would like to build a fish pond
on top of it.

Our idea is to use breeze blocks (18 inches x 9 inches) three high
(circa 28 inches high in total) and 14 foot x 11 foot. We then thought
of rendering then painting the outside of the breeze blocks, leave the
inside of the breeze blocks au natural and bung in a big liner.

Then I thought of the weight of all that water! Will the breeze blocks
remain standing or would the whole lot collapse once filled up with
water (or worse still, once stocked with fish)!

If anybody has any experience they could share, or head me in the
direction of a useful site on this subject, I would be most grateful.

Regards,
