How to build gravel pad?

(1/2) > >>

da_guy2:
We've ordered a Nordic Warrior XL 110v which should be here in 6-8 weeks. Or dealer asked that we have either a gravel pad or a poured concrete pad. I'm opting for gravel as I'd rather not have a giant slab of concrete in our yard (nor do I think it's necessary for a smaller tub like ours). The only problem is they didn't provide and details beyond that it must be level. Does anyone have any recommendations? I.e. depth, type of stone to use, etc? I like the idea of pea gravel but I could foresee it being an issue. Also, would a reinforcing grid (i.e. something like this https://iowatgroupinc.com/handygrid#/diy-concretefree-base-for-hot-tubs) be a good idea or is it overkill for a smaller tub like ours?

@da_guy2, what did you end up with? I just purchased a Nordic Escape MS and am wondering if I can support it with gravel and a product like the one you mentioned.

Good solid compacted class 2 or better 4-6" deep will be fine. (where do you live?) But I prefer a built up design like of course a slab, but wood, decking or e-z pad or a solid base of some sort will be fine. Frost, soft ground, a lot of things need to be factored in........

Ended up digging down just shy of 8 inches. Lined the hole with a geotextile. Filed with 6" of high-performance bedding (1/4" crushed limestone with the fines cleaned off) in 1-2" layers compacting between each layer.

Topped it with ecoraster grid https://www.ecorastergrid.com/. It's a german product similar to the other one I linked before but was able to find a company selling it locally for 1/2 what the other one would have cost. I then filled the grid with a combination of the bedding mix in the middle and pea gravel around the outside.

So far so good but the big test is how it'll hold up over time.
