This is for a Bullfrog Spa. You should always check with your local codes for the base of your Bullfrog Spa. Bullfrog spas recommend a gravel base if it is allowed in your area and it works best with the wood-free dura base and dura frame. I've added a link to the Bullfrog spas owners' manual check out page 38 [ Ссылка ] page 38
For those who don't believe that gravel cannot hold the weight or support heavy loads, please google

The ballast also holds the track in place as the trains roll over it. A variety of materials have been used as track ballast, including crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay. We are doing the same thing. Again if your area doesn't allow it, don't use it.
