I am pouring a concrete slab 4" thick, how long should I wait before putting a hot tub on it?

Question

We will not be putting water in the hot tub for several weeks, the tub weighs appox. 800 pounds.

Answer 1

concrete can be walked on a couple of hours after its poured. You can place your hot tub on it a couple of days after its set up

Answer 2

Pour the slab, seal it, then wait a few days....by then the concrete will have cured enough for the tub and the water. Concrete takes 28 days to cure fully, but after about a week, it will test at 3/4 of the final strength.

Answer 3

If the concrete is on soil, with no damp barrier (landscaping fabric), and no steel in it, i doubt it will last past winter, your hot tub weighs 800 pounds, water weighs 2 pounds per pint and bodies weigh differently, potentially, you could easily have 1,500 - 2000 pounds in weight, when full of water and bodies.

Answer 4

the longer you let it dry the stronger it will become
although you can walk on it within a few hours if you wish to have it stand the test of time
concrete takes 30 days to completely cure
if you arent going to add water for a few weeks hold off putting the hottub on the slab and keep it damp for those weeks it will give you a much harder slab. covering it with palstic will allow it to cure slowly and wetting it down once a day will let it cure slowly

Answer 5

i would seal the concrete in a few days after pouring and set the hot tub in about a week. i hope with that weight you used rebar under and throughout the concrete :)

Answer 6

You should cure (keep covered and damp) a concrete slab for a minimum of seventy two hours and not subject it to heavy loads until six days after that.

Answer 7
