25 x 12 meter swimming pool

Postby Bjornqa » Fri Nov 18, 2016 7:53 pm

A friend of mine are starting on a big "public pool" next week. 25 X 12 meters.
We having a discussion on how thick the floor need to be, and how thick reinforced steel etc... anyone whit experience or an edjucated answer ????

Allmost all picture and information i can find uses 12mm steel - two layers - 20x20 spacing and 20cm thick floor. But shorty its not enough for this pool ?????

It vill be a 1,2 to 1,6 deep. Overflow. Saltwater.

This is not really the place for advice like this. In view of the THB 6mio+ budget involved, the services of a professional pool consultant should be engaged , substrate tests made, and proper blueprints need to be prepared. The steel and concrete proposed above is inadequate.

The water pressure on bottom of 1.2 - 1.6 m water depth at pool 25x12m is the same as at any other size (e.g. 4x3m).
Only difference (against the narrow width) could be where the ground water level is rising up to the terrain surface level, and the pool would not be full of water.

Yes the water pressure is the same, but not the weight of the water.

You need use both to decide your structure, together with the structure of the ground it will be sitting in. So you need a professional to get it right.

What about the foundations: Footings/piles, ground beams, etc.? Walls?
