news Obviously popping some polystyrene board down the side of a pool as
its
being back filled takes care of the sides, but is there any thing
strong
enough to stand the weight of a pool 7 foot deep? I.e., is there a
product that i can install in the hole that i can build the pool on?

any suggestions?

Few layers of Kingspan?


Yes around the side i suppose. Underneath i don't know if it'd handle
the
compression. Can anyone work out the compressive load of 2 meters of
water? i.e. using supabloc 7, could it cope with the weight?

6 feet of water is equivalent of 0.019 kg/mm^2, well within the limits of
Supabloc7. Expanded Polystyrene or kingspan would be more than adequate
with 100mm of reinforced concrete slab above it.

The force against the sides at the bottom would be similar.


ta for this. So King span is strong enough? cool. Yes it is an out side
pool situated in France. I will be heating it by solar panels and my aim is
to make it useable for as much of the year as possible.

Ok, so i go with king span. Do i go with their thickest sheet or does it
matter much? Obviously i need the pool to be stable over a good few years,
so no movement in the floor is essential. Should i lay them directly on the
bottom of the hole i dig, or add a concrete slab under it as well as the
pool bottom slab over it?
